1313a24d0b fix(locales): remove the word "hack" from the description of Anubis

the localization as appropriate.

![](./around-the-bend.webp)
As we finish up work on [all of the features in the next release of Anubis](/docs/CHANGELOG#unreleased), I took a moment to add up the financials and here's an update on the recurring revenue of the project. Once I reach the [$5000 per month](https://github.com/TecharoHQ/anubis/discussions/278) mark, I can start reducing hours at my dayjob and start to make working on Anubis my full time job.
{/* truncate */}
Note that this only counts _recurring_ revenue (subscriptions to [BotStopper](/docs/admin/botstopper) and monthly repeating donations). Every one of the one-time donations I get is a gift and I am grateful for them, but I cannot make critically important financial decisions off of sporadic one-time donations.
:::note
All currency figures in this article are USD (United States Dollars) unless denoted otherwise.
:::
Here's the funding breakdown by income stream:
```mermaid
pie title Funding update August 2025
"GitHub Sponsors" : 3500
"Patreon" : 1500
"Liberapay" : 100
"Remaining" : 4800
```
Assuming that some of my private support contracts and other sales effort go through, this will slightly change the shapes of this (a new pie chart segment will emerge for "Manual invoices"), but I am halfway there. This is a huge bar to pass and as it stands right now this is just enough income to pay for my monthly rent (not accounting for tax).
As a reminder, here's the rough plan for the phases I want to hit based on the _recurring_ donation totals:
| Monthly donations | Details |
| :-------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| $0-5,000 per month | Anubis is a nights and weekends project based on how much spare time and energy I have. |
| $5,000-10,000 per month | Anubis gets 1-2 days per week of my time put into it consistently and I go part-time at my dayjob. |
| $10,000-15,000 per month | Anubis becomes my full time job. Features that are currently exclusive to [BotStopper](/docs/admin/botstopper/) start to trickle down to the open source version of Anubis. |
| $15,000 per month and above | I start planning hiring for Techaro. |
If your organization benefits from Anubis, please consider donating to the project in order to make this sustainable. The fewer financial problems I have means the more that Anubis can become better.
## New funding platform: Liberapay
After many comments about the funding options, I have set up [Liberapay](https://liberapay.com/Xe/) as an option to receive donations. Additional funding targets will be added to Liberapay as soon as I hear back from my accountant with more information. All money received via Liberapay goes directly towards supporting the project.
## Next goals
Here's my short term goals for the immediate future:
1. Finish [Thoth](/docs/admin/thoth/) and run a backfill to mass issue API keys.
2. Document and publish the writeup for the multi-region Google Cloud spot instance setup that Thoth is built upon.
3. Release v1.22.0 of Anubis with Traefik support and other important fixes.
4. Continue growing the project into a sustainable business.
5. Work through the [blog backlog](https://github.com/TecharoHQ/anubis/issues?q=is%3Aissue%20state%3Aopen%20label%3Ablog) to document the thoughts behind Anubis and how parts of it work.
Thank you for supporting Anubis! It's only going to get better from here.

title: Sometimes CPU cores are odd
description: "TL;DR: all the assumptions you have about processor design are wrong and if you are unlucky you will never run into problems that users do through sheer chance."

import ProofOfWorkDiagram from "./ProofOfWorkDiagram";
![](./parc-dsilence.webp)
One of the biggest lessons that I've learned in my career is that all software has bugs, and the more complicated your software gets the more complicated your bugs get. A lot of the time those bugs will be fairly obvious and easy to spot, validate, and replicate. Sometimes, the process of fixing it will uncover your core assumptions about how things work in ways that will leave you feeling like you just got trolled.
Today I'm going to talk about a single line fix that prevents people on a large number of devices from having weird irreproducible issues with Anubis rejecting people when it frankly shouldn't. Stick around, it's gonna be a wild ride.
{/* truncate */}
## How this happened
Anubis is a web application firewall that tries to make sure that the client is a browser. It uses a few [challenge methods](/docs/admin/configuration/challenges/) to do this determination, but the main method is the [proof of work](/docs/admin/configuration/challenges/proof-of-work/) challenge which makes clients grind away at cryptographic checksums in order to rate limit clients from connecting too eagerly.
:::note
In retrospect implementing the proof of work challenge may have been a mistake and it's likely to be supplanted by things like [Proof of React](https://github.com/TecharoHQ/anubis/pull/1038) or other methods that have yet to be developed. Your patience and polite behaviour in the bug tracker is appreciated.
:::
In order to make sure the proof of work challenge screen _goes away as fast as possible_, the [worker code](https://github.com/TecharoHQ/anubis/tree/main/web/js/worker) is optimized within an inch of its digital life. One of the main ways that this code is optimized is with how it's run. Over the last 10-20 years, the main way that CPUs have gotten fast is via increasing multicore performance. Anubis tries to make sure that it can use as many cores as possible in order to take advantage of your device's CPU as much as it can.
This strategy sometimes has some issues though, for one Firefox seems to get _much slower_ if you have Anubis try to absolutely saturate all of the cores on the system. It also has a fairly high overhead between JavaScript JIT code and [WebCrypto](https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API). I did some testing and found out that Firefox's point of diminishing returns was about half of the CPU cores.
## Another "invalid response" bug
One of the complaints I've been getting from users and administrators using Anubis is that they've been running into issues where users get randomly rejected with an error message only saying "invalid response". This happens when the challenge validating process fails. This issue has been blocking the release of the next version of Anubis.
In order to demonstrate this better, I've made a little interactive diagram for the proof of work process:
<ProofOfWorkDiagram />
I've fixed a lot of the easy bugs in Anubis by this point. A lot of what's left is the hard bugs, but also specifically the kinds of hard bugs that involve weird hardware configurations. In order to try and catch these issues before software hits prod, I test Anubis against a bunch of hardware I have locally. Any issues I find and fix before software ships are issues that you don't hit in production.
Let's consider [the line of code](https://github.com/TecharoHQ/anubis/blob/main/web/js/algorithms/fast.mjs) that was causing this issue:
```js
threads = Math.max(navigator.hardwareConcurrency / 2, 1),
```
This is intended to make your browser spawn a proof of work worker for _half_ of your available CPU cores. If you only have one CPU core, you should only have one worker. Each thread is given this number of threads and uses that to increment the nonce so that each thread doesn't try to find a solution that another worker has already performed.
One of the subtle problems here is that all of the parts of this assume that the thread ID and nonce are integers without a decimal portion. Famously, [all JavaScript numbers are IEEE 754 floating point numbers](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number). Surely there wouldn't be a case where the thread count could be a _decimal_ number, right?
Here's all the devices I use to test Anubis _and their core counts_:
| Device Name | Core Count |
| :--------------------------- | :--------- |
| MacBook Pro M3 Max | 16 |
| MacBook Pro M4 Max | 16 |
| AMD Ryzen 9 7950x3D | 32 |
| Google Pixel 9a (GrapheneOS) | 8 |
| iPhone 15 Pro Max | 6 |
| iPad Pro (M1) | 8 |
| iPad mini | 6 |
| Steam Deck | 8 |
| Core i5 10600 (homelab) | 12 |
| ROG Ally | 16 |
Notice something? All of those devices have an _even_ number of cores. Some devices such as the [Pixel 8 Pro](https://www.gsmarena.com/google_pixel_8_pro-12545.php) have an _odd_ number of cores. So what happens with that line of code as the JavaScript engine evaluates it?
Let's replace the [`navigator.hardwareConcurrency`](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/hardwareConcurrency) with the Pixel 8 Pro's 9 cores:
```js
threads = Math.max(9 / 2, 1),
```
Then divide it by two:
```js
threads = Math.max(4.5, 1),
```
Oops, that's not ideal. However `4.5` is bigger than `1`, so [`Math.max`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/max) returns that:
```js
threads = 4.5,
```
This means that each time the proof of work equation is calculated, there is a 50% chance that a valid solution would include a nonce with a decimal portion in it. If the client finds a solution with such a nonce, then it would think the client was successful and submit the solution to the server, but the server only expects whole numbers back so it rejects that as an invalid response.
I keep telling more junior people that when you have the weirdest, most inconsistent bugs in software that it's going to boil down to the dumbest possible thing you can possibly imagine. People don't believe me, then they encounter bugs like this. Then they suddenly believe me.
Here is the fix:
```js
threads = Math.trunc(Math.max(navigator.hardwareConcurrency / 2, 1)),
```
This uses [`Math.trunc`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/trunc) to truncate away the decimal portion so that the Pixel 8 Pro has `4` workers instead of `4.5` workers.
## Today I learned this was possible
This was a total "today I learned" moment. I didn't actually think that hardware vendors shipped processors with an odd number of cores, however if you look at the core geometry of the Pixel 8 Pro, it has _three_ tiers of processor cores:
| Core type | Core model | Number |
| :----------------- | :------------------- | :----- |
| High performance | 3 Ghz Cortex X3 | 1 |
| Medium performance | 2.45 Ghz Cortex A715 | 4 |
| High efficiency | 2.15 Cortex A510 | 4 |
| Total | | 9 |
I guess every assumption that developers have about CPU design is probably wrong.
This probably isn't helped by the fact that for most of my career, the core count in phones has been largely irrelevant and most of the desktop / laptop CPUs I've had (where core count does matter) uses [simultaneous multithreading](https://en.wikipedia.org/wiki/Simultaneous_multithreading) to "multiply" the core count by two.
The client side fix is a bit of an "emergency stop" button to try and mitigate the badness as early as possible. In general I'm quite aware of the terrible UX involved with this flow failing and I'm still noodling through ways to make that UX better and easier for users / administrators to debug.
I'm looking into the following:
1. This could have been prevented on the server side by doing less strict input validation in compliance with [Postel's Law](https://en.wikipedia.org/wiki/Robustness_principle). I feel nervous about making such a security-sensitive endpoint _more liberal_ with the inputs it can accept, but it may be fine? I need to consult with a security expert.
2. Showing an encrypted error message on the "invalid response" page so that the user and administrator can work together to fix or report the issue. I remember Google doing this at least once, but I can't recall where I've seen it in the past. Either way, this is probably the most robust method even though it would require developing some additional tooling. I think it would be worth it.
I'm likely going to go with the second option. I will need to figure out a good flow for this. It's likely going to involve [age](https://github.com/FiloSottile/age). I'll say more about this when I have more to say.
In the meantime though, looks like I need to expense a used Pixel 8 Pro to add to the testing jungle for Anubis. If anyone has a deal out there, please let me know!
Thank you to the people that have been polite and helpful when trying to root cause and fix this issue.

title: Taking steps to end abusive traffic from cloud providers
description: "Learn how to effectively file abuse reports with cloud providers to stop malicious traffic at its source and protect your services from automated abuse."
authors: [xe]
tags: [abuse, cloud, security, networking]

![A peaceful goose pond](./goose-pond.webp)
As part of Anubis's ongoing development, I've been working to reduce friction for legitimate users by minimizing unnecessary challenge pages. While this improves the user experience, it can potentially expose services to increased abuse from public cloud infrastructure. To help administrators better protect their services, I want to share my strategies for filing abuse reports with IP space owners, enabling us to address malicious scraping at its source.
{/* truncate */}
In general, there are two kinds of IP addresses:
- Residential IP addresses: IP addresses that are allocated to residential customers such as home internet connections and cellular data plans. These IP addresses are increasingly shared between customers due to technologies like [CGNAT](https://en.wikipedia.org/wiki/Carrier-grade_NAT).
- Commercial IP addresses: IP addresses that are allocated to commercial customers such as cloud providers, VPS providers, root server providers, and other such business to business companies. These IP addresses are almost always statically allocated to one customer for a very long period of time (typically the lifetime of the server unless they are using things like dedicated IP addresses).
In general, filing abuse reports to residential IP addresses is a waste of time. The administrators do appreciate knowing what kinds of abusive traffic is causing grief, but many times the users of those IP addresses don't know that their computer is sending abusive traffic to your services. A lot of malware botnets that used to be used with DDOS for hire services are now being used as residential proxies. Those "free VPN apps" are almost certainly making you pay for your usage by making your computer a zombie in a botnet. At some level I really respect the hustle as they manage to sell other people's bandwidth for rates as ludicrous as $1.00 per gigabyte ingressed and egressed.
:::note
Keep in mind, I'm talking about the things you can find by searching "free VPN", not infrastructure for the public good like the Tor browser or I2P.
:::
What you should really focus on is traffic from commercial IP addresses, such as cloud providers. That's a case where the cloud customer is in direct violation of the acceptable use policy of the provider. Filing abuse reports gets the abuse team of the cloud provider to reach out to that customer and demand corrective action under threat of contractual violence.
## How to make an abuse report
In general, the best abuse reports contain the following information:
- Time of abusive requests.
- IP address, User-Agent header, or other unique identifiers that can help the abuse team educate the customer about their misbehaving infrastructure.
- Does the abusive IP address request robots.txt? If not, be sure to include that information.
- A brief description of the impact to your system such as high system load, pages not rendering, or database system crashes. This helps the provider establish the fact that their customer is causing you measurable harm.
- Context as to what your service is, what it does, and why they should care.
For example, let's say that someone was giving the Anubis docs a series of requests that caused the server to fall over and experience extended downtime. Here's what I would write to the abuse contact:
> Hello,
>
> I have received abusive traffic from one of your customers that has resulted in a denial of service to the users of the Anubis documentation website. Anubis is a web application firewall that administrators use to protect their websites against mass scraping and this documentation website helps administrators get started.
>
> On or about Thursday, October 30th at 04:00 UTC, A flurry of requests from the IP range `127.34.0.0/24` started to hit the `/admin/` routes, which caused unreasonable database load and ended up crashing PostgreSQL. This caused the documentation website to go down for three hours as it happened while the administrators were asleep. Based on logs, this caused 353 distinct users to not be able to load the documentation and the users filed bugs about it.
>
> I have attached the HTTP frontend logs for the abusive requests from your IP range. To protect our systems in the meantime while we perform additional hardening, I have blocked that IP address range in both our IP firewall and web application firewall configuration. Based on these logs, your customer seems to not have requested the standard `robots.txt` file, which includes instructions to deny access to those routes.
>
> Please let me know what other information you need on your end.
>
> Sincerely,
>
> [normal email signature]
Then in order to figure out where to send it, look the IP addresses up in the `whois` database. For example, if you want to find the abuse contact for the IP address `1.1.1.1`, use the [whois command](https://packages.debian.org/sid/whois) to find the abuse contact:
```
$ whois 1.1.1.1 | grep -i abuse
% Abuse contact for '1.1.1.0 - 1.1.1.255' is 'helpdesk@apnic.net'
abuse-c: AA1412-AP
remarks: All Cloudflare abuse reporting can be done via
remarks: resolver-abuse@cloudflare.com
abuse-mailbox: helpdesk@apnic.net
role: ABUSE APNICRANDNETAU
abuse-mailbox: helpdesk@apnic.net
mnt-by: APNIC-ABUSE
```
The abuse contact will be named either `abuse-c` or `abuse-mailbox`. For greatest effect, I suggest including all listed email addresses in your email to the abuse contact.
Once you send your email, you should expect a response within 2 business days at most. If they don't get back to you, please feel free to [contact me](https://xeiaso.net/contact/) so that the default set of Anubis rules can be edited according to patterns I'm seeing across the ecosystem.
Just remember that many cloud providers do not know how bad the scraping problem is. Filing abuse complaints makes it their problem. They don't want it to be their problem.

## v1.24.0: Y'shtola Rhul
Anubis is back and better than ever! Lots of minor fixes with some big ones interspersed.
- Fix panic when validating challenges after privacy-mode browsers strip headers and the follow-up request matches an `ALLOW` threshold.
- Expose WEIGHT rule matches as Prometheus metrics.
- Allow more OCI registry clients [based on feedback](https://github.com/TecharoHQ/anubis/pull/1253#issuecomment-3506744184).
- Expose services directory in the embedded `(data)` filesystem.
- Add Ukrainian locale ([#1044](https://github.com/TecharoHQ/anubis/pull/1044)).
- Allow Renovate as an OCI registry client.
- Properly handle 4in6 addresses so that IP matching works with those addresses.
- Add support to simple Valkey/Redis cluster mode
- Open Graph passthrough now reuses the configured target Host/SNI/TLS settings, so metadata fetches succeed when the upstream certificate differs from the public domain. ([1283](https://github.com/TecharoHQ/anubis/pull/1283))
- Stabilize the CVE-2025-24369 regression test by always submitting an invalid proof instead of relying on random POW failures.
- Refine the check that ensures the presence of the Accept header to avoid breaking docker clients.
- Removed rules intended to reward actual browsers due to abuse in the wild.
### Dataset poisoning
Anubis has the ability to engage in [dataset poisoning attacks](https://www.anthropic.com/research/small-samples-poison) using the [dataset poisoning subsystem](./admin/honeypot/overview.mdx). This allows every Anubis instance to be a honeypot to attract and flag abusive scrapers so that no administrator action is required to ban them.
There is much more information about this feature in [the dataset poisoning subsystem documentation](./admin/honeypot/overview.mdx). Administrators that are interested in learning how this feature works should consult that documentation.
### Deprecate `report_as` in challenge configuration
Previously Anubis let you lie to users about the difficulty of a challenge to interfere with operators of malicious scrapers as a psychological attack:
```yaml
bots:
# Punish any bot with "bot" in the user-agent string
# This is known to have a high false-positive rate, use at your own risk
- name: generic-bot-catchall
user_agent_regex: (?i:bot|crawler)
action: CHALLENGE
challenge:
difficulty: 16 # impossible
report_as: 4 # lie to the operator
algorithm: slow # intentionally waste CPU cycles and time
```
This has turned out to be a bad idea because it has caused massive user experience problems and has been removed. If you are using this setting, you will get a warning in your logs like this:
```json
{
"time": "2025-11-25T23:10:31.092201549-05:00",
"level": "WARN",
"source": {
"function": "github.com/TecharoHQ/anubis/lib/policy.ParseConfig",
"file": "/home/xe/code/TecharoHQ/anubis/lib/policy/policy.go",
"line": 201
},
"msg": "use of deprecated report_as setting detected, please remove this from your policy file when possible",
"at": "config-validate",
"name": "mild-suspicion"
}
```
To remove this warning, remove this setting from your policy file.
### Logging customization
Anubis now supports the ability to log to multiple backends ("sinks"). This allows you to have Anubis [log to a file](./admin/policies.mdx#file-sink) instead of just logging to standard out. You can also customize the [logging level](./admin/policies.mdx#log-levels) in the policy file:
```yaml
logging:
level: "warn" # much less verbose logging
sink: file # log to a file
parameters:
file: "./var/anubis.log"
maxBackups: 3 # keep at least 3 old copies
maxBytes: 67108864 # each file can have up to 64 Mi of logs
maxAge: 7 # rotate files out every n days
oldFileTimeFormat: 2006-01-02T15-04-05 # RFC 3339-ish
compress: true # gzip-compress old log files
useLocalTime: false # timezone for rotated files is UTC
```
Additionally, information about [how Anubis uses each logging level](./admin/policies.mdx#log-levels) has been added to the documentation.
### DNS Features
- CEL expressions for:
- FCrDNS checks
- Forward DNS queries
- Reverse DNS queries
- `arpaReverseIP` to transform IPv4/6 addresses into ARPA reverse IP notation.
- `regexSafe` to escape regex special characters (useful for including `remoteAddress` or headers in regular expressions).
- DNS cache and other optimizations to minimize unnecessary DNS queries.
The DNS cache TTL can be changed in the bots config like this:
```yaml
dns_ttl:
forward: 600
reverse: 600
```
The default value for both forward and reverse queries is 300 seconds.
The `verifyFCrDNS` CEL function has two overloads:
- `(addr)`
Simply verifies that the remote side has PTR records pointing to the target address.
- `(addr, ptrPattern)`
Verifies that the remote side refers to a specific domain and that this domain points to the target IP.
## v1.23.1: Lyse Hext - Echo 1
- Fix `SERVE_ROBOTS_TXT` setting after the double slash fix broke it.
### Potentially breaking changes
#### Remove default Tencent Cloud block rule
v1.23.0 added a default rule to block Tencent Cloud. After an email from their abuse team where they promised to take action to clean up their reputation, I have removed the default block rule. If this network causes you problems, please contact [abuse@tencent.com](mailto:abuse@tencent.com) and supply the following information:
- Time of abusive requests.
- IP address, User-Agent header, or other unique identifiers that can help the abuse team educate the customer about their misbehaving infrastructure.
- Does the abusive IP address request robots.txt? If not, be sure to include that information.
- A brief description of the impact to your system such as high system load, pages not rendering, or database system crashes. This helps the provider establish the fact that their customer is causing you measurable harm.
- Context as to what your service is, what it does, and why they should care.
Mention that you are using Anubis or BotStopper to protect your services. If they do not respond to you, please [contact me](https://xeiaso.net/contact) as soon as possible.
#### Docker / OCI registry clients
Anubis v1.23.0 accidentally blocked Docker / OCI registry clients. In order to explicitly allow them, add an import for `(data)/clients/docker-client.yaml`:
```yaml
bots:
- import: (data)/meta/default-config.yaml
- import: (data)/clients/docker-client.yaml
```
This is technically a regression as these clients used to work in Anubis v1.22.0, however it is allowable to make this opt-in as most websites do not expect to be serving Docker / OCI registry client traffic.
## v1.23.0: Lyse Hext
- Add default tencent cloud DENY rule.
- Added `(data)/meta/default-config.yaml` for importing the entire default configuration at once.

### Potentially breaking changes
#### Multiple checks at once has and-like semantics instead of or-like semantics
Anubis lets you stack multiple checks at once with blocks like this:
```yaml
name: allow-prometheus
action: ALLOW
user_agent_regex: ^prometheus-probe$
remote_addresses:
- 192.168.2.0/24
```
Previously, this only returned ALLOW if _any one_ of the conditions matched. This behaviour has changed to only return ALLOW if _all_ of the conditions match. I expect this to have some issues with user configs, however this fix is grave enough that it's worth the risk of breaking configs. If this bites you, please let me know so we can make an escape hatch.
### Better error messages
In order to make it easier for legitimate clients to debug issues with their browser configuration and Anubis, Anubis will emit internal error detail in base 64 so that administrators can chase down issues. Future versions of this may also include a variant that encrypts the error detail messages.
### Bug Fixes
Sometimes the enhanced temporal assurance in [#1038](https://github.com/TecharoHQ/anubis/pull/1038) and [#1068](https://github.com/TecharoHQ/anubis/pull/1068) could backfire because Chromium and its ilk randomize the amount of time they wait in order to avoid a timing side channel attack. This has been fixed by both increasing the amount of time a client has to wait for the metarefresh and preact challenges as well as making the server side logic more permissive.
## v1.22.0: Yda Hext
> Someone has to make an effort at reconciliation if these conflicts are ever going to end.
In this release, we finally fix the odd number of CPU cores bug, pave the way for lighter weight challenges, make Anubis more adaptable, and more.
### Big ticket items
#### Proof of React challenge
A new ["proof of React"](./admin/configuration/challenges/preact.mdx) has been added. It runs a simple app in React that has several chained hooks. It is much more lightweight than the proof of work check.
#### Smaller features
- Downstream consumers can change the default [log/slog#Logger](https://pkg.go.dev/log/slog#Logger) instance that Anubis uses by setting `opts.Logger` to your slog instance of choice ([#864](https://github.com/TecharoHQ/anubis/issues/864)).
- The [Thoth client](https://anubis.techaro.lol/docs/admin/thoth) is now public in the repo instead of being an internal package.
- [Custom-AsyncHttpClient](https://github.com/AsyncHttpClient/async-http-client)'s default User-Agent has an increased weight by default ([#852](https://github.com/TecharoHQ/anubis/issues/852)).
- The [`segments`](./admin/configuration/expressions.mdx#segments) function was added for splitting a path into its slash-separated segments.
- Added possibility to disable HTTP keep-alive to support backends not properly handling it.
- When issuing a challenge, Anubis stores information about that challenge into the store. That stored information is later used to validate challenge responses. This works around nondeterminism in bot rules. ([#917](https://github.com/TecharoHQ/anubis/issues/917))
- One of the biggest sources of lag in Firefox has been eliminated: the use of WebCrypto. Now whenever Anubis detects the client is using Firefox (or Pale Moon), it will swap over to a pure-JS implementation of SHA-256 for speed.
- When parsing [Open Graph tags](./admin/configuration/open-graph.mdx), add any URLs found in the responses to a temporary "allow cache" so that social preview images work.
- Proof of work solving has had a complete overhaul and rethink based on feedback from browser engine developers, frontend experts, and overall performance profiling.
- One of the biggest sources of lag in Firefox has been eliminated: the use of WebCrypto. Now whenever Anubis detects the client is using Firefox (or Pale Moon), it will swap over to a pure-JS implementation of SHA-256 for speed.
- Optimize the performance of the pure-JS Anubis solver.
- Web Workers are stored as dedicated JavaScript files in `static/js/workers/*.mjs`.
- Pave the way for non-SHA256 solver methods and eventually one that uses WebAssembly (or WebAssembly code compiled to JS for those that disable WebAssembly).
- Legacy JavaScript code has been eliminated.
- When parsing [Open Graph tags](./admin/configuration/open-graph.mdx), add any URLs found in the responses to a temporary "allow cache" so that social preview images work.
- The hard dependency on WebCrypto has been removed, allowing a proof of work challenge to work over plain (unencrypted) HTTP.
- The Anubis version number is put in the footer of every page.
- Add a default block rule for Huawei Cloud.
- Add a default block rule for Alibaba Cloud.
- Added support to use Traefik forwardAuth middleware.
- Add X-Request-URI support so that Subrequest Authentication has path support.
- Added glob matching for `REDIRECT_DOMAINS`. You can pass `*.bugs.techaro.lol` to allow redirecting to anything ending with `.bugs.techaro.lol`. There is a limit of 4 wildcards.
### Fixes
#### Odd numbers of CPU cores are properly supported
Some phones have an odd number of CPU cores. This caused [interesting issues](https://anubis.techaro.lol/blog/2025/cpu-core-odd). This was fixed by [using `Math.trunc` to convert the number of CPU cores back into an integer](https://github.com/TecharoHQ/anubis/issues/1043).
#### Smaller fixes
- A standard library HTTP server log message about HTTP pipelining not working has been filtered out of Anubis' logs. There is no action that can be taken about it.
- Added a missing link to the Caddy installation environment in the installation documentation.
- Downstream consumers can change the default [log/slog#Logger](https://pkg.go.dev/log/slog#Logger) instance that Anubis uses by setting `opts.Logger` to your slog instance of choice ([#864](https://github.com/TecharoHQ/anubis/issues/864)).
- The [Thoth client](https://anubis.techaro.lol/docs/admin/thoth) is now public in the repo instead of being an internal package.
- [Custom-AsyncHttpClient](https://github.com/AsyncHttpClient/async-http-client)'s default User-Agent has an increased weight by default ([#852](https://github.com/TecharoHQ/anubis/issues/852)).
- Add option for replacing the default explanation text with a custom one ([#747](https://github.com/TecharoHQ/anubis/pull/747))
- The contact email in the LibreJS header has been changed.
- The hard dependency on WebCrypto has been removed, allowing a proof of work challenge to work over plain (unencrypted) HTTP.
- Firefox for Android support has been fixed by embedding the challenge ID into the pass-challenge route. This also fixes some inconsistent issues with other mobile browsers.
- The Anubis version number is put in the footer of every page.
- The legacy JSON based policy file example has been removed and all documentation for how to write a policy file in JSON has been deleted. JSON based policy files will still work, but YAML is the superior option for Anubis configuration.
- A standard library HTTP server log message about HTTP pipelining not working has been filtered out of Anubis' logs. There is no action that can be taken about it.
- The default `favicon` pattern in `data/common/keep-internet-working.yaml` has been updated to permit requests for png/gif/jpg/svg files as well as ico.
- The `--cookie-prefix` flag has been fixed so that it is fully respected.
- The default patterns in `data/common/keep-internet-working.yaml` have been updated to appropriately escape the '.' character in the regular expression patterns.
- Add optional restrictions for JWT based on the value of a header ([#697](https://github.com/TecharoHQ/anubis/pull/697))
- The word "hack" has been removed from the translation strings for Anubis due to incidents involving people misunderstanding that word and sending particularly horrible things to the project lead over email.
- Bump AI-robots.txt to version 1.39
- Inject adversarial input to break AI coding assistants.
- Add better logging when using Subrequest Authentication.
### Security-relevant changes
- Add a server-side check for the meta-refresh challenge that makes sure clients have waited for at least 95% of the time that they should.
#### Fix potential double-spend for challenges
Anubis operates by issuing a challenge and having the client present a solution for that challenge. Challenges are identified by a unique UUID, which is stored in the database.
The problem is that a challenge could potentially be used twice by a dedicated attacker making a targeted attack against Anubis. Challenge records did not have a "spent" or "used" field. In total, a dedicated attacker could solve a challenge once and reuse that solution across multiple sessions in order to mint additional tokens.
This was fixed by adding a "spent" field to challenges in the data store. When a challenge is solved, that "spent" field gets set to `true`. If a future attempt to solve this challenge is observed, it gets rejected.
With the advent of store based challenge issuance in [#749](https://github.com/TecharoHQ/anubis/pull/749), this means that these challenge IDs are [only good for 30 minutes](https://github.com/TecharoHQ/anubis/blob/e8dfff635015d6c906dddd49cb0eaf591326092a/lib/anubis.go#L130-L135d). Websites using the most recent version of Anubis have limited exposure to this problem.
Websites using older versions of Anubis have a much more increased exposure to this problem and are encouraged to keep this software updated as often and as frequently as possible.
Thanks to [@taviso](https://github.com/taviso) for reporting this issue.
### Breaking changes
- The "slow" frontend solver has been removed in order to reduce maintenance burden. Any existing uses of it will still work, but issue a warning upon startup asking administrators to upgrade to the "fast" frontend solver.
- The legacy JSON based policy file example has been removed and all documentation for how to write a policy file in JSON has been deleted. JSON based policy files will still work, but YAML is the superior option for Anubis configuration.

### Header-based overlay dispatch
If you run BotStopper in a multi-tenant environment where each tenant needs its own branding, BotStopper supports the ability to use request header values to direct asset reads to different folders under your `OVERLAY_FOLDER`. One of the most common ways to do this is based on the HTTP Host of the request. For example, if you set `ASSET_LOOKUP_HEADER=Host` in BotStopper's environment:
```text
$OVERLAY_FOLDER
├── static
│ ├── css
│ │ ├── custom.css
│ │ └── eyesore.css
│ └── img

└── reject.webp
```
Requests to `test.anubis.techaro.lol` will load assets in `$OVERLAY_FOLDER/test.anubis.techaro.lol/static` and all other requests will load them from `$OVERLAY_FOLDER/static`.

## Custom HTML templates
If you need to completely control the HTML layout of all Anubis pages, you can customize the entire page with `USE_TEMPLATES=true`. This uses Go's standard library [html/template](https://pkg.go.dev/html/template) package to template HTML responses. Your templates can contain whatever HTML you want. The only catch is that you MUST include `{{ .Head }}` in the `<head>` element for challenge pages, and you MUST include `{{ .Body }}` in the `<body>` element for all pages.
In order to use this, you must define the following templates:
| Template path | Usage |
| :----------------------------------------- | :---------------------------------------------- |
| `$OVERLAY_FOLDER/templates/challenge.tmpl` | Challenge pages |
| `$OVERLAY_FOLDER/templates/error.tmpl` | Error pages |
| `$OVERLAY_FOLDER/templates/impressum.tmpl` | [Impressum](./configuration/impressum.mdx) page |
:::note
Currently HTML templates don't work together with [Header-based overlay dispatch](#header-based-overlay-dispatch). This is a known issue that will be fixed soon. If you enable header-based overlay dispatch, BotStopper will use the global `templates` folder instead of using the templates present in the overlay.
:::
Here are minimal (but working) examples for each template:
<details>
<summary>`challenge.tmpl`</summary>
:::note
You **MUST** include the `{{.Head}}` segment in a `<head>` tag. It contains important information for challenges to execute. If you don't include this, no clients will be able to pass challenges.

# Client IP Headers
Currently Anubis will always flatten the `X-Forwarded-For` when it contains multiple IP addresses. From right to left, the first IP address that is not in one of the following categories will be set as `X-Forwarded-For` in the request passed to the upstream.
- Private (`XFF_STRIP_PRIVATE`, enabled by default)
- CGNAT (always stripped)
- Link-local Unicast (always stripped)
```
Incoming: X-Forwarded-For: 1.2.3.4, 5.6.7.8, 10.0.0.1
Upstream: X-Forwarded-For: 5.6.7.8
```
This behavior will cause problems if the proxy in front of Anubis is from a public IP, such as Cloudflare, because Anubis will use the Cloudflare IP instead of your client's real IP. You will likely see all requests from your browser being blocked and/or an infinite challenge loop.
```
Incoming: X-Forwarded-For: REAL_CLIENT_IP, CF_IP
Upstream: X-Forwarded-For: CF_IP
```
As a workaround, you should configure your web server to parse an alternative source (such as `CF-Connecting-IP`), or pre-process the incoming `X-Forwarded-For` with your web server to ensure it only contains the real client IP address, then pass it to Anubis as `X-Forwarded-For`.
If you do not control the web server upstream of Anubis, the `custom-real-ip-header` command line flag accepts a header value that Anubis will read the real client IP address from. Anubis will set the `X-Real-IP` header to the IP address found in the custom header.
The `X-Real-IP` header will be automatically inferred from `X-Forwarded-For` if not set, setting it explicitly is not necessary as long as `X-Forwarded-For` contains only the real client IP. However setting it explicitly can eliminate spoofed values if your web server doesn't set this.
See [Cloudflare](environments/cloudflare.mdx) for an example configuration.

Anubis can also perform DNS lookups as a part of its expression evaluation. This can be useful for doing things like checking for a valid [Forward-confirmed reverse DNS (FCrDNS)](https://en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS) record.
#### `arpaReverseIP`

#### `lookupHost`

```ts
function lookupHost(host: string): string[];
```
`lookupHost` performs a DNS lookup for the given hostname and returns a list of IP addresses.
```yaml

```
#### `reverseDNS`

```
`reverseDNS` takes an IP address and returns the DNS names associated with it. This is useful when you want to check PTR records of an IP address.
```yaml
- name: allow-googlebot
action: ALLOW
expression: 'reverseDNS(remoteAddress).endsWith(".googlebot.com")'
```
::: warning
Do not use this for validating the legitimacy of an IP address. It is possible for DNS records to be out of date or otherwise manipulated. Use [`verifyFCrDNS`](#verifyfcrdns) instead for a more reliable result.
:::
#### `verifyFCrDNS`
Available in `bot` expressions.
```ts
function verifyFCrDNS(ip: string): bool;
function verifyFCrDNS(ip: string, pattern: string): bool;
```
`verifyFCrDNS` checks if the reverse DNS of an IP address matches its forward DNS. This is a common technique to filter out spam and bot traffic. `verifyFCrDNS` comes in two forms:
- `verifyFCrDNS(remoteAddress)` will check that the reverse DNS of the remote address resolves back to the remote address. If no PTR records, returns true.
- `verifyFCrDNS(remoteAddress, pattern)` will check that the reverse DNS of the remote address is matching with pattern and that name resolves back to the remote address.
This is best used in rules like this:
```yaml
- name: require-fcrdns-for-post
action: DENY
expression:
all:
- method == "POST"
- "!verifyFCrDNS(remoteAddress)"
```
Here is an another example that allows requests from telegram:
```yaml
- name: telegrambot
action: ALLOW
expression:
all:
- userAgent.matches("TelegramBot")
- verifyFCrDNS(remoteAddress, "ptr\\.telegram\\.org$")
```
## Life advice
Expressions are very powerful. This is a benefit and a burden. If you are not careful with your expression targeting, you will be liable to get yourself into trouble. If you are at all in doubt, throw a `CHALLENGE` over a `DENY`. Legitimate users can easily work around a `CHALLENGE` result with a [proof of work challenge](../../design/why-proof-of-work.mdx). Bots are less likely to be able to do this.

## Configuring allowed redirect domains
By default, Anubis may redirect to any domain which could cause security issues in the unlikely case that an attacker passes a challenge for your browser and then tricks you into clicking a link to your domain.
One can restrict the domains that Anubis can redirect to when passing a challenge by setting up `REDIRECT_DOMAINS` environment variable.
If you need to set more than one domain, fill the environment variable with a comma-separated list of domain names.
There is also glob matching support. You can pass `*.bugs.techaro.lol` to allow redirecting to anything ending with `.bugs.techaro.lol`. There is a limit of 4 wildcards.
By default, Anubis will limit redirects to be on the same HTTP Host that Anubis is running on (EG: requests to yoursite.com cannot redirect outside of yoursite.com). If you need to set more than one domain, fill the `REDIRECT_DOMAINS` environment variable with a comma-separated list of domain names that Anubis should allow redirects to.
:::note
If you are hosting Anubis on a non-standard port (`https://example:com:8443`, `http://www.example.net:8080`, etc.), you must also include the port number here.
These domains are _an exact string match_, they do not support wildcard matches.

Anubis can be used with the [`forward_auth`](https://caddyserver.com/docs/caddyfile/directives/forward_auth) directive in Caddy.
First, the `TARGET` environment variable in Anubis must be set to a space, eg:
<Tabs>
<TabItem value="env-file" label="Environment file" default>
```shell
# anubis.env
TARGET=" "
# ...

</TabItem>
</Tabs>
Then configure the necessary directives in your site block:
```caddy

title: Dataset poisoning
---
Anubis offers the ability to participate in [dataset poisoning](https://www.anthropic.com/research/small-samples-poison) attacks similar to what [iocaine](https://iocaine.madhouse-project.org/) and other similar tools offer. Currently this is in a preview state where a lot of details are hard-coded in order to test the viability of this approach.
In essence, when Anubis challenge and error pages are rendered they include a small bit of HTML code that browsers will ignore but scrapers will interpret as a link to ingest. This will then create a small forest of recursive nothing pages that are designed according to the following principles:
- These pages are _cheap_ to render, rendering in at most ten milliseconds on decently specced hardware.
- These pages are _vacuous_, meaning that they essentially are devoid of content such that a human would find it odd and click away, but a scraper would not be able to know that and would continue through the forest.
- These pages are _fairly large_ so that scrapers don't think that the pages are error pages or are otherwise devoid of content.
- These pages are _fully self-contained_ so that they load fast without incurring additional load from resource fetches.
In this limited preview state, Anubis generates pages using [spintax](https://outboundly.ai/blogs/what-is-spintax-and-how-to-use-it/). Spintax is a syntax that is used to create different variants of utterances for use in marketing messages and email spam that evades word filtering. In its current form, Anubis' dataset poisoning has AI generated spintax that generates vapid LinkedIn posts with some western occultism thrown in for good measure. This results in utterances like the following:
> There's a moment when visionaries are being called to realize that the work can't be reduced to optimization, but about resonance. We don't transform products by grinding endlessly, we do it by holding the vision. Because meaning can't be forced, it unfolds over time when culture are in integrity. This moment represents a fundamental reimagining in how we think about work. This isn't a framework, it's a lived truth that requires courage. When we get honest, we activate nonlinear growth that don't show up in dashboards, but redefine success anyway.
This should be fairly transparent to humans that this is pseudoprofound anti-content and is a signal to click away.
## Plans
Future versions of this feature will allow for more customization. In the near future this will be configurable via the following mechanisms:
- WebAssembly logic for customizing how the poisoning data is generated (with examples including the existing spintax method).
- Weight thresholds and logic for how they are interpreted by Anubis.
- Other configuration settings as facts and circumstances dictate.
## Implementation notes
In its current implementation, the Anubis dataset poisoning feature has the following flaws that may hinder production deployments:
- All Anubis instances use the same method for generating dataset poisoning information. This may be easy for malicious actors to detect and ignore.
- Anubis dataset poisoning routes are under the `/.within.website/x/cmd/anubis` URL hierarchy. This may be easy for malicious actors to detect and ignore.
Right now Anubis assigns 30 weight points if the following criteria are met:
- A client's User-Agent has been observed in the dataset poisoning maze at least 25 times.
- The network-clamped IP address (/24 for IPv4 and /48 for IPv6) has been observed in the dataset poisoning maze at least 25 times.
Additionally, when any given client by both User-Agent and network-clamped IP address has been observed, Anubis will emit log lines warning about it so that administrative action can be taken up to and including [filing abuse reports with the network owner](/blog/2025/file-abuse-reports).

Anubis uses these environment variables for configuration:
| Environment Variable | Default value | Explanation |
|:-------------------------------|:------------------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `ASSET_LOOKUP_HEADER` | unset | <EO /> If set, use the contents of this header in requests when looking up custom assets in `OVERLAY_FOLDER`. See [Header-based overlay dispatch](./botstopper.mdx#header-based-overlay-dispatch) for more details. |
| `BASE_PREFIX` | unset | If set, adds a global prefix to all Anubis endpoints (everything starting with `/.within.website/x/anubis/`). For example, setting this to `/myapp` would make Anubis accessible at `/myapp/` instead of `/`. This is useful when running Anubis behind a reverse proxy that routes based on path prefixes. |
| `BIND` | `:8923` | The network address that Anubis listens on. For `unix`, set this to a path: `/run/anubis/instance.sock` |
| `BIND_NETWORK` | `tcp` | The address family that Anubis listens on. Accepts `tcp`, `unix` and anything Go's [`net.Listen`](https://pkg.go.dev/net#Listen) supports. |
| `CHALLENGE_TITLE` | unset | <EO /> If set, override the translation stack to show a custom title for challenge pages such as "Making sure your connection is secure!". See [Customizing messages](./botstopper.mdx#customizing-messages) for more details. |
| `COOKIE_DOMAIN` | unset | The domain the Anubis challenge pass cookie should be set to. This should be set to the domain you bought from your registrar (EG: `techaro.lol` if your webapp is running on `anubis.techaro.lol`). See this [stackoverflow explanation of cookies](https://stackoverflow.com/a/1063760) for more information.<br/><br/>Note that unlike `REDIRECT_DOMAINS`, you should never include a port number in this variable. |
| `COOKIE_DYNAMIC_DOMAIN` | false | If set to true, automatically set cookie domain fields based on the hostname of the request. EG: if you are making a request to `anubis.techaro.lol`, the Anubis cookie will be valid for any subdomain of `techaro.lol`. |
| `COOKIE_EXPIRATION_TIME` | `168h` | The amount of time the authorization cookie is valid for. |
| `CUSTOM_REAL_IP_HEADER` | unset | If set, Anubis will read the client's real IP address from this header, and set it in `X-Real-IP` header. |
| `COOKIE_PARTITIONED` | `false` | If set to `true`, enables the [partitioned (CHIPS) flag](https://developers.google.com/privacy-sandbox/cookies/chips), meaning that Anubis inside an iframe has a different set of cookies than the domain hosting the iframe. |
| `COOKIE_PREFIX` | `anubis-cookie` | The prefix used for browser cookies created by Anubis. Useful for customization or avoiding conflicts with other applications. |
| `COOKIE_SECURE` | `true` | If set to `true`, enables the [Secure flag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/Cookies#block_access_to_your_cookies), meaning that the cookies will only be transmitted over HTTPS. If Anubis is used in an unsecure context (plain HTTP), this will be need to be set to false |
| `COOKIE_SAME_SITE` | `None` | Controls the cookies [`SameSite` attribute](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie#samesitesamesite-value). Allowed: `None`, `Lax`, `Strict`, `Default`. `None` permits cross-site use but modern browsers require it to be **Secure**—so if `COOKIE_SECURE=false` or you serve over plain HTTP, use `Lax` (recommended) or `Strict` or the cookie will be rejected. `Default` uses the Go runtimes `SameSiteDefaultMode`. `None` will be downgraded to `Lax` automatically if cookie is set NOT to be secure. |
| `DIFFICULTY` | `4` | The difficulty of the challenge, or the number of leading zeroes that must be in successful responses. |
| `DIFFICULTY_IN_JWT` | `false` | If set to `true`, adds the `difficulty` field into JWT claims, which indicates the difficulty the token has been generated. This may be useful for statistics and debugging. |
| `ED25519_PRIVATE_KEY_HEX` | unset | The hex-encoded ed25519 private key used to sign Anubis responses. If this is not set, Anubis will generate one for you. This should be exactly 64 characters long. **Required when using persistent storage backends** (like bbolt) to ensure challenges survive service restarts. When running multiple instances on the same base domain, the key must be the same across all instances. See below for details. |
| `ED25519_PRIVATE_KEY_HEX_FILE` | unset | Path to a file containing the hex-encoded ed25519 private key. Only one of this or its sister option may be set. **Required when using persistent storage backends** (like bbolt) to ensure challenges survive service restarts. When running multiple instances on the same base domain, the key must be the same across all instances. |
| `ERROR_TITLE` | unset | <EO /> If set, override the translation stack to show a custom title for error pages such as "Something went wrong!". See [Customizing messages](./botstopper.mdx#customizing-messages) for more details. |
| `JWT_RESTRICTION_HEADER` | `X-Real-IP` | If set, the JWT is only valid if the current value of this header matches the value when the JWT was created. You can use it e.g. to restrict a JWT to the source IP of the user using `X-Real-IP`. |
| `METRICS_BIND` | `:9090` | The network address that Anubis serves Prometheus metrics on. See `BIND` for more information. |
| `METRICS_BIND_NETWORK` | `tcp` | The address family that the Anubis metrics server listens on. See `BIND_NETWORK` for more information. |
| `OG_EXPIRY_TIME` | `24h` | The expiration time for the Open Graph tag cache. Prefer using [the policy file](./configuration/open-graph.mdx) to configure the Open Graph subsystem. |
| `OG_PASSTHROUGH` | `false` | If set to `true`, Anubis will enable Open Graph tag passthrough. Prefer using [the policy file](./configuration/open-graph.mdx) to configure the Open Graph subsystem. |
| `OG_CACHE_CONSIDER_HOST` | `false` | If set to `true`, Anubis will consider the host in the Open Graph tag cache key. Prefer using [the policy file](./configuration/open-graph.mdx) to configure the Open Graph subsystem. |
| `OVERLAY_FOLDER` | unset | <EO /> If set, treat the given path as an [overlay folder](./botstopper.mdx#custom-images-and-css), allowing you to customize CSS, fonts, images, and add other assets to BotStopper deployments. |
| `POLICY_FNAME` | unset | The file containing [bot policy configuration](./policies.mdx). See the bot policy documentation for more details. If unset, the default bot policy configuration is used. |
| `PUBLIC_URL` | unset | The externally accessible URL for this Anubis instance, used for constructing redirect URLs (e.g., for Traefik forwardAuth). Leave it unset when Anubis terminates traffic directly (sidecar/standalone deployments) or redirect building will fail with `redir=null`. |
| `REDIRECT_DOMAINS` | unset | Comma-separated list of domain names that Anubis should allow redirects to when passing a challenge. See [Redirect Domain Configuration](./configuration/redirect-domains) for more details. |
| `SERVE_ROBOTS_TXT` | `false` | If set `true`, Anubis will serve a default `robots.txt` file that disallows all known AI scrapers by name and then additionally disallows every scraper. This is useful if facts and circumstances make it difficult to change the underlying service to serve such a `robots.txt` file. |
| `SLOG_LEVEL` | `INFO` | The log level for structured logging. Valid values are `DEBUG`, `INFO`, `WARN`, and `ERROR`. Set to `DEBUG` to see all requests, evaluations, and detailed diagnostic information. |

| `STRIP_BASE_PREFIX` | `false` | If set to `true`, strips the base prefix from request paths when forwarding to the target server. This is useful when your target service expects to receive requests without the base prefix. For example, with `BASE_PREFIX=/foo` and `STRIP_BASE_PREFIX=true`, a request to `/foo/bar` would be forwarded to the target as `/bar`. |
| `TARGET` | `http://localhost:3923` | The URL of the service that Anubis should forward valid requests to. Supports Unix domain sockets, set this to a URI like so: `unix:///path/to/socket.sock`. |
| `USE_REMOTE_ADDRESS` | unset | If set to `true`, Anubis will take the client's IP from the network socket. For production deployments, it is expected that a reverse proxy is used in front of Anubis, which pass the IP using headers, instead. |

| :----------------------------- | :---------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `BASE_PREFIX` | unset | If set, adds a global prefix to all Anubis endpoints (everything starting with `/.within.website/x/anubis/`). For example, setting this to `/myapp` would make Anubis accessible at `/myapp/` instead of `/`. This is useful when running Anubis behind a reverse proxy that routes based on path prefixes. |
| `BIND` | `:8923` | The network address that Anubis listens on. For `unix`, set this to a path: `/run/anubis/instance.sock` |
| `BIND_NETWORK` | `tcp` | The address family that Anubis listens on. Accepts `tcp`, `unix` and anything Go's [`net.Listen`](https://pkg.go.dev/net#Listen) supports. |
| `COOKIE_DOMAIN` | unset | The domain the Anubis challenge pass cookie should be set to. This should be set to the domain you bought from your registrar (EG: `techaro.lol` if your webapp is running on `anubis.techaro.lol`). See this [stackoverflow explanation of cookies](https://stackoverflow.com/a/1063760) for more information.<br/><br/>Note that unlike `REDIRECT_DOMAINS`, you should never include a port number in this variable. |
| `COOKIE_DYNAMIC_DOMAIN` | false | If set to true, automatically set cookie domain fields based on the hostname of the request. EG: if you are making a request to `anubis.techaro.lol`, the Anubis cookie will be valid for any subdomain of `techaro.lol`. |
| `COOKIE_EXPIRATION_TIME` | `168h` | The amount of time the authorization cookie is valid for. |
| `COOKIE_PARTITIONED` | `false` | If set to `true`, enables the [partitioned (CHIPS) flag](https://developers.google.com/privacy-sandbox/cookies/chips), meaning that Anubis inside an iframe has a different set of cookies than the domain hosting the iframe. |
| `COOKIE_SECURE` | `true` | If set to `true`, enables the [Secure flag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/Cookies#block_access_to_your_cookies), meaning that the cookies will only be transmitted over HTTPS. If Anubis is used in an unsecure context (plain HTTP), this will be need to be set to false |
| `DIFFICULTY` | `4` | The difficulty of the challenge, or the number of leading zeroes that must be in successful responses. |
| `ED25519_PRIVATE_KEY_HEX` | unset | The hex-encoded ed25519 private key used to sign Anubis responses. If this is not set, Anubis will generate one for you. This should be exactly 64 characters long. When running multiple instances on the same base domain, the key must be the same across all instances. See below for details. |
| `ED25519_PRIVATE_KEY_HEX_FILE` | unset | Path to a file containing the hex-encoded ed25519 private key. Only one of this or its sister option may be set. |
| `JWT_RESTRICTION_HEADER` | `X-Real-IP` | If set, the JWT is only valid if the current value of this header matches the value when the JWT was created. You can use it e.g. to restrict a JWT to the source IP of the user using `X-Real-IP`. |
| `METRICS_BIND` | `:9090` | The network address that Anubis serves Prometheus metrics on. See `BIND` for more information. |
| `METRICS_BIND_NETWORK` | `tcp` | The address family that the Anubis metrics server listens on. See `BIND_NETWORK` for more information. |
| `OG_EXPIRY_TIME` | `24h` | The expiration time for the Open Graph tag cache. Prefer using [the policy file](./configuration/open-graph.mdx) to configure the Open Graph subsystem. |
| `OG_PASSTHROUGH` | `false` | If set to `true`, Anubis will enable Open Graph tag passthrough. Prefer using [the policy file](./configuration/open-graph.mdx) to configure the Open Graph subsystem. |
| `OG_CACHE_CONSIDER_HOST` | `false` | If set to `true`, Anubis will consider the host in the Open Graph tag cache key. Prefer using [the policy file](./configuration/open-graph.mdx) to configure the Open Graph subsystem. |
| `POLICY_FNAME` | unset | The file containing [bot policy configuration](./policies.mdx). See the bot policy documentation for more details. If unset, the default bot policy configuration is used. |
| `PUBLIC_URL` | unset | The externally accessible URL for this Anubis instance, used for constructing redirect URLs (e.g., for Traefik forwardAuth). |
| `REDIRECT_DOMAINS` | unset | If set, restrict the domains that Anubis can redirect to when passing a challenge.<br/><br/>If this is unset, Anubis may redirect to any domain which could cause security issues in the unlikely case that an attacker passes a challenge for your browser and then tricks you into clicking a link to your domain.<br/><br/>Note that if you are hosting Anubis on a non-standard port (`https://example:com:8443`, `http://www.example.net:8080`, etc.), you must also include the port number here. |
| `SERVE_ROBOTS_TXT` | `false` | If set `true`, Anubis will serve a default `robots.txt` file that disallows all known AI scrapers by name and then additionally disallows every scraper. This is useful if facts and circumstances make it difficult to change the underlying service to serve such a `robots.txt` file. |
| `SOCKET_MODE` | `0770` | _Only used when at least one of the `*_BIND_NETWORK` variables are set to `unix`._ The socket mode (permissions) for Unix domain sockets. |
| `STRIP_BASE_PREFIX` | `false` | If set to `true`, strips the base prefix from request paths when forwarding to the target server. This is useful when your target service expects to receive requests without the base prefix. For example, with `BASE_PREFIX=/foo` and `STRIP_BASE_PREFIX=true`, a request to `/foo/bar` would be forwarded to the target as `/bar`. |

title: iplist2rule CLI tool
---
The `iplist2rule` tool converts IP blocklists into Anubis challenge policies. It reads common IP block list formats and generates the appropriate Anubis policy file for IP address filtering.
## Installation
Install directly with Go
```bash
go install github.com/TecharoHQ/anubis/utils/cmd/iplist2rule@latest
```
## Usage
Basic conversion from URL:
```bash
iplist2rule https://raw.githubusercontent.com/7c/torfilter/refs/heads/main/lists/txt/torfilter-1m-flat.txt filter-tor.yaml
```
Explicitly allow every IP address on a list:
```bash
iplist2rule --action ALLOW https://raw.githubusercontent.com/7c/torfilter/refs/heads/main/lists/txt/torfilter-1m-flat.txt filter-tor.yaml
```
Add weight to requests matching IP addresses on a list:
```bash
iplist2rule --action WEIGH --weight 20 https://raw.githubusercontent.com/7c/torfilter/refs/heads/main/lists/txt/torfilter-1m-flat.txt filter-tor.yaml
```
## Options
| Flag | Description | Default |
| :------------ | :----------------------------------------------------------------------------------------------- | :-------------------------------- |
| `--action` | The Anubis action to take for the IP address in question, must be in ALL CAPS. | `DENY` (forbids traffic) |
| `--rule-name` | The name for the generated Anubis rule, should be in kebab-case. | (not set, inferred from filename) |
| `--weight` | When `--action=WEIGH`, how many weight points should be added or removed from matching requests? | 0 (not set) |
## Using the Generated Policy

### `s3api`
A network-backed storage layer backed by [object storage](https://en.wikipedia.org/wiki/Object_storage), specifically using the [S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Type_API_Reference.html). This can be backed by any S3-compatible object storage service such as:
- [AWS S3](https://aws.amazon.com/s3/)
- [Cloudflare R2](https://www.cloudflare.com/developer-platform/products/r2/)
- [Hetzner Object Storage](https://www.hetzner.com/storage/object-storage/)
- [Minio](https://www.min.io/)
- [Tigris](https://www.tigrisdata.com/)
If you are using a cloud platform, they likely provide an S3 compatible object storage service. If not, you may want to choose [one of the fastest options](https://www.tigrisdata.com/blog/benchmark-small-objects/).
| Should I use this backend? | Yes/no |

| Are you running only one instance of Anubis for this service? | 🚫 No |
| Does your service get a lot of traffic? | ✅ Yes |
| Do you want to store data persistently when Anubis restarts? | ✅ Yes |
| Do you run Anubis without mutable filesystem storage? | ✅ Yes |
:::note
Using this backend will cause a lot of S3 operations, at least one for creating challenges, one for invalidating challenges, one for updating challenges to prevent double-spends, and one for removing challenges.
:::
#### Configuration
The `s3api` backend takes the following configuration options:
| Name | Type | Example | Description |
| :----------- | :------ | :------------ | :------------------------------------------------------------------------------------------------------------------------------------------ |
| `bucketName` | string | `anubis-data` | (Required) The name of the dedicated bucket for Anubis to store information in. |
| `pathStyle` | boolean | `false` | If true, use path-style S3 API operations. Please consult your storage provider's documentation if you don't know what you should put here. |
:::note
You should probably enable a lifecycle expiration rule for buckets containing Anubis data. Here is an example policy:
```json
{
"Rules": [
{
"Status": "Enabled",
"Expiration": {
"Days": 7
}
}
]
}
```
Adjust this as facts and circumstances demand, but 7 days should be enough for anyone.

Example:
Assuming your environment looks like this:
```sh
# All of the following are fake credentials that look like real ones.

AWS_SECRET_ACCESS_KEY=thereIsNoWayABeeShouldBeAbleToFly
AWS_REGION=yow
AWS_ENDPOINT_URL_S3=https://yow.s3.probably-not-malware.lol

## Logging management
Anubis has very verbose logging out of the box. This is intentional and allows administrators to be sure that it is working merely by watching it work in real time. Some administrators may not appreciate this level of logging out of the box. As such, Anubis lets you customize details about how it logs data.
Anubis uses a practice called [structured logging](https://stackify.com/what-is-structured-logging-and-why-developers-need-it/) to emit log messages with key-value pair context. In order to make analyzing large amounts of log messages easier, Anubis encodes all logs in JSON. This allows you to use any tool that can parse JSON to perform analytics or monitor for issues.
Anubis exposes the following logging settings in the policy file:
| Name | Type | Example | Description |
| :----------- | :----------------------- | :-------------- | :--------------------------------------------------------------------------------------------------------------------------------------- |
| `level` | [log level](#log-levels) | `info` | The logging level threshold. Any logs that are at or above this threshold will be drained to the sink. Any other logs will be discarded. |
| `sink` | string | `stdio`, `file` | The sink where the logs drain to as they are being recorded in Anubis. |
| `parameters` | object | | Parameters for the given logging sink. This will vary based on the logging sink of choice. See below for more information. |
Anubis supports the following logging sinks:
1. `file`: logs are emitted to a file that is rotated based on size and age. Old log files are compressed with gzip to save space. This allows for better integration with users that decide to use legacy service managers (OpenRC, FreeBSD's init, etc).
2. `stdio`: logs are emitted to the standard error stream of the Anubis process. This allows runtimes such as Docker, Podman, Systemd, and Kubernetes to capture logs with their native logging subsystems without any additional configuration.
### Log levels
Anubis uses Go's [standard library `log/slog` package](https://pkg.go.dev/log/slog) to emit structured logs. By default, Anubis logs at the [Info level](https://pkg.go.dev/log/slog#Level), which is fairly verbose out of the box. Here are the possible logging levels in Anubis:
| Log level | Use in Anubis |
| :-------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `DEBUG` | The raw unfiltered torrent of doom. Only use this if you are actively working on Anubis or have very good reasons to use it. |
| `INFO` | The default logging level, fairly verbose in order to make it easier for automation to parse. |
| `WARN` | A "more silent" logging level. Much less verbose. Some things that are now at the `info` level need to be moved up to the `warn` level in future patches. |
| `ERROR` | Only log error messages. |
Additionally, you can set a "slightly higher" log level if you need to, such as:
```yaml
logging:
sink: stdio
level: "INFO+1"
```
This isn't currently used by Anubis, but will be in the future for "slightly important" information.
### `file` sink
The `file` sink makes Anubis write its logs to the filesystem and rotate them out when the log file meets certain thresholds. This logging sink takes the following parameters:
| Name | Type | Example | Description |
| :------------- | :-------------- | :-------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `file` | string | `/var/log/anubis.log` | The file where Anubis logs should be written to. Make sure the user Anubis is running as has write and file creation permissions to this directory. |
| `maxBackups` | number | `3` | The number of old log files that should be maintained when log files are rotated out. |
| `maxBytes` | number of bytes | `67108864` (64Mi) | The maximum size of each log file before it is rotated out. |
| `maxAge` | number of days | `7` | If a log file is more than this many days old, rotate it out. |
| `compress` | boolean | `true` | If true, compress old log files with gzip. This should be set to `true` and is only exposed as an option for dealing with legacy workflows where there is magical thinking about log files at play. |
| `useLocalTime` | boolean | `false` | If true, use the system local time zone to create log filenames instead of UTC. This should almost always be set to `false` and is only exposed for legacy workflows where there is magical thinking about time zones at play. |
```yaml
logging:
sink: file
parameters:
file: "./var/anubis.log"
maxBackups: 3 # keep at least 3 old copies
maxBytes: 67108864 # each file can have up to 64 Mi of logs
maxAge: 7 # rotate files out every n days
compress: true # gzip-compress old log files
useLocalTime: false # timezone for rotated files is UTC
```
When files are rotated out, the old files will be named after the rotation timestamp in [RFC 3339 format](https://www.rfc-editor.org/rfc/rfc3339).
### `stdio` sink
By default, Anubis logs everything to the standard error stream of its process. This requires no configuration:
```yaml
logging:
sink: stdio
```
If you use a service orchestration platform that does not capture the standard error stream of processes, you need to use a different logging sink.
## Risk calculation for downstream services
