Some thoughts on how useful Anubis really is. Combined with comments I read elsewhere about scrapers starting to solve the challenges, I’m afraid Anubis will be outdated soon and we need something else.

Yeah, well-written stuff. I think Anubis will come and go. This beautifully demonstrates and, best of all, quantifies the
negligencenegligible cost to scrapers of Anubis.It’s very interesting to try to think of what would work, even conceptually. Some sort of purely client-side captcha type of thing perhaps. I keep thinking about it in half-assed ways for minutes at a time.
Maybe something that scrambles the characters of the site according to some random “offset” of some sort, e.g maybe randomly selecting a modulus size and an offset to cycle them, or even just a good ol’ cipher. And the “captcha” consists of a slider that adjusts the offset. You as the viewer know it’s solved when the text becomes something sensical - so there’s no need for the client code to store a readable key that could be used to auto-undo the scrambling. You could maybe even have some values of the slider randomly chosen to produce English text if the scrapers got smart enough to check for legibility (not sure how to hide which slider positions would be these red herring ones though) - which could maybe be enough to trick the scraper into picking up junk text sometimes.
@mfed1122 @tofu any client-side tech to avoid (some of the) bots is bound to, as its popularity grows, be either circumvented by the bot’s developers or the model behind the bot will have picked up enough to solve it
I don’t see how any of these are going to do better than a short term patch
That’s the great thing about Anubis: it’s not client-side. Not entirely anyways. Similar to public key encryption schemes, it exploits the computational complexity of certain functions to solve the challenge. It can’t just say “solved, let me through” because the client has to calculate a number, based on the parameters of the challenge, that fits certain mathematical criteria, and then present it to the server. That’s the “proof of work” component.
A challenge could be something like “find the two prime factors of the semiprime
1522605027922533360535618378132637429718068114961380688657908494580122963258952897654000350692006139”. This number is known as RSA-100, it was first factorized in 1991, which took several days of CPU time, but checking the result is trivial since it’s just integer multiplication. A similar semiprime of 260 decimal digits still hasn’t been factorized to this day. You can’t get around mathematics, no matter how advanced your AI model is.@rtxn I don’t understand how that isn’t client side?
Anything that is client side can be, if not spoofed, then at least delegated to a sub process, and my argument stands
Please, explain to us how you expect to spoof a math problem that you have to provide an answer to the server before proceeding.
You can math all you want on the client, but the server isn’t going to give you shit until you provide the right answer.
@Passerby6497 I really don’t understand the issue here
If there is a challenge to solve, then the server has provided that to the client
There is no way around this, is there?
You’re given the challenge to solve by the server, yes. But just because the challenge is provided to you, that doesn’t mean you can fake your way through it.
You still have to calculate the answer before you can get any farther. You can’t bullshit/spoof your way through the math problem to bypass it, because your correct answer is required to proceed.
Unless the server gives you a well-known problem you have the answer to/is easily calculated, or you find a vulnerability in something like Anubis to make it accept a wrong answer, not really. You’re stuck at the interstitial page with a math prompt until you solve it.
Unless I’m misunderstanding your position, I’m not sure what the disconnect is. The original question was about spoofing the challenge client side, but you can’t really spoof the answer to a complicated math problem unless there’s an issue with the server side validation.
@Passerby6497 my stance is that the LLM might recognize that the best way to solve the problem is to run chromium and get the answer from there, then pass it on?
Congrats on doing it the way the website owner wants! You’re now into the content, and you had to waste seconds of processing power to do so (effectively being throttled by the owner), so everyone is happy. You can’t overload the site, but you can still get there after a short wait.
I’m sure you meant to sound more analytical than anything… but this really comes off as arrogant.
You make the claim that Anubis is negligent and come and go, and then admit ton only spending minutes at a time thinking of solutions yourself, which you then just sorta spout. It’s fun to think about solutions to this problem collectively, but can you honestly believe that Anubis is negligent when it’s so clearly working and when the author has been so extremely clear about their own perception of its pitfalls and hasty development (go read their blog, it’s a fun time).
