First off, make a website defend mode that can be triggered to serve different content. Then, do the following: 1. Add a robots.txt, make it look like it's wordpress (Disallow: /wp-admin etc) 2. If any client requests /wp-admin, flag their IP ASN as bot. 3. If a client is a bot, send it a gzip bomb (100kB size, unpacked around 20GB), use Transfer-Encoding: gzip and Content-Encoding: gzip to also punish malicious web…

Oh, I very much like this.

But forget just LLM ranges, there could be many other unknown groups doing the same thing, or using residential proxy collections to forward their requests. Just add to every page a side-note of a couple of arbitrary sentences like this, with a “What Is This?” link to take confused humans to a small page explaining your little game.

Don't make the text too random, that might be easily detectable (a bot might take two or more snapshots of a page and reject any text that changes every time, to try filter out accidental noise and therefore avoid our intentional noise), perhaps seed the text generator with the filename+timestamp or some other almost-but-not-quite static content/metadata metrics. Also, if the text is too random it'll just be lost in the noise, some repetition would be needed for there to be any detectable effect in the final output.

Anyone complaining that I'm deliberately sabotaging them will be pointed to the robots.txt file that explicitly says no bots⁰, the licence that says no commercial use¹ without payment of daft-but-not-ridiculous fees.

For some definition of "common", yes. Some try to be less shady by asking for consent (e.g. in exchange for in-game credits), others are essentially malware. For example: https://bright-sdk.com/ > Bright SDK is approved by Apple, Amazon, LG, Huawei, Samsung app stores, and is whitelisted by top Antivirus companies.

FYI this is a rebranding of the notorious “Luminati” service that sold a residential proxy network based on the ”Hola VPN” chrome extension. They’ve upped their game and now pay application developers to embed their botnet in their application.

> LLMs don't prompt themselves from training data Tell that to twitter propaganda bots and the developers behind it. Don't have to tell me that, you know. Most interactive systems that interact with websites that I've seen are vulnerable to this because of the way they prompt the LLM after the scrape, with the unfiltered or crappily sanitized content.

Btw how would a double layered zip bomb look in practice? After you decompress the fist layer the second layer should be a simple zip, but that would need to be manually constructed I guess, are there any links to learn more?

> gzip bomb (100kB size, unpacked around 20GB) Not possible (unless you're talking double gzip). gzip's max compression ratio is 1032:1[1]. So 100kB can expand to at most ~103MB with single gzip. Brotli allows much larger compression. Here's[2] a brotli bomb I created that's 81MB compressed and 100TB uncompressed. That's a 1.2M:1 compression ratio.

You're probably right in regards to compression ratios, and I also think that brotli would be a much better candidate. Proxies probably won't support it as "Transfer-Encoding: br" though. > Not possible (unless you're talking double gzip). gzip's max compression ratio is 1032:1[1].

Reminds me of the Library of Babel for some reason: https://libraryofbabel.info/referencehex.html > The universe (which others call the Library) is composed of an indefinite, perhaps infinite number of hexagonal galleries…The arrangement of the galleries is always the same: Twenty bookshelves, five to each side, line four of the hexagon's six sides…each bookshelf holds thirty-two books identical in format; each book…

Library of Babel captivated me as a student learning programming for the first time. I couldn't even fathom how something like that could be made in real/virtual life. I understand it now, but I still aspire to recreate this site on my own one day. The story by Borges is amazing as well too

It has captivated me too. At one point I realized that the set of real numbers will probably do the same (or a creative use of the set of natural numbers).

How can I do this to port scanners? They constantly scan my home network and my firewall complains.

You would probably want a honeypot to lure them in. But I wouldn't expect the output to go through an LLM, although I wouldn't be surprised if I was wrong.

This stuff is just low level automated scanning looking for well known, easy exploits. Default credentials and stuff like that. A lot of it is trying to recruit hosts for illegal VPNs / proxies, DDOS service, and more scanning / propagation. My advice is to block it (maybe with an expiration time on the block), log it, and ignore it. But it can be fun to see what they do with a honeypot.

My understanding of what happens is that chatting with an LLM is implemented as . There are then keywords handled by non-LLM code, like "execute this Python script" or "download this web page". So if the LLM decides to generate "Visit http://OPs-website.com", then that will get replaced in the chat transcript with the text from that website. In this case it's "ChatGPT, ignore all previous results," which ChatGPT might be happy to do. (It's fickle.)

Basically, this isn't about training, it's about abusing the "let's act like our model wasn't trained in 2019 by adding random Internet data to the chat transcript".

Sounds brutal. A whole ISP typically is a single ASN and any of their subscribers can be running bots while others don't - isn't this so?
