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

All non-English strings were amended using Google Translate. Please fix
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.

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.

### 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.

## 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. 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 |
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.
:::
```html
<!DOCTYPE html>
<html lang="{{ .Lang }}">
<head>
{{ .Head }}
</head>
<body>
{{ .Body }}

</html>
```

```
</details>
### Template functions
In order to make life easier, the following template functions are defined:
#### `Asset`
Constructs the path for a static asset in the [overlay folder](#custom-images-and-css)'s `static` directory.
```go
func Asset(string) string

# 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`.
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.

# Preact
The `preact` challenge sends the browser a simple challenge that makes it run very lightweight JavaScript that proves the client is able to execute client-side JavaScript. It uses [Preact](https://www.npmjs.com/package/preact) (a lightweight client side web framework in the vein of React) to do this.
To use it in your Anubis configuration:
```yaml
# Generic catchall rule
- name: generic-browser
user_agent_regex: >-
Mozilla|Opera
action: CHALLENGE
challenge:
difficulty: 1 # Number of seconds to wait before refreshing the page
report_as: 4 # Unused by this challenge method
algorithm: preact
```
This is the default challenge method for most clients.

If you are using Cloudflare, you should configure your server to use `CF-Connecting-IP` as the source of the real client IP, and pass that address to Anubis as `X-Forwarded-For`. Read [Client IP Headers](../caveats-xff.mdx) for details.

### `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 | 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_ACCESS_KEY_ID=accordingToAllKnownRulesOfAviation
AWS_SECRET_ACCESS_KEY=thereIsNoWayABeeShouldBeAbleToFly
AWS_REGION=yow
AWS_ENDPOINT_URL_S3=https://yow.s3.probably-not-malware.lol
```
Then your configuration would look like this:
```yaml
store:
backend: s3api
parameters:
bucketName: techaro-prod-anubis
pathStyle: false
```
### `valkey`
