there's so much untapped potential for ai agents on CTF challenges, especially in web and cryptography. imagine a system that finds relevant writeups, searches through papers, automatically debugs failed exploits - it would instantly solve all easy-medium challenges

introducing (Ch)eetCode – the easiest way to get past those pesky technical interviews! open leetcode, toggle the extension, and watch the LLM breeze through the problem as you pretend to type your solution. disclaimer: please do not use this in real life 🙃

Bumblebee: a tiny vision transformer for image classification that runs locally in the browser with WASM! Built this over the past few nights: huge shout out to @karparthy 's tutorials, the Rust book, and @huggingface 's Candle framework. Try it out:

@immad - cheap (< $100) and efficient automated penetration testing. Typical security firm tests take weeks and cost more than $10k -- we're building semantic agents/algorithms that replace manual analysis effort with more robust and efficient detection.

some thoughts: - "... by Wong Kar-Wai" emulates the neon + hazy nighttime style quite well - v6 generates very photorealistic images! had to intentionally specify blurring and haziness - does a good job at generating psuedo-chinese characters

@moyix Yes! RsaCtfTool is a great tool, but often the challenge is slightly modified so the exact attack doesn’t work. I’m planning to use the underlying source code as an exploit library - letting the LLM decide which attack code to use and adapt the script correspondingly

also played with image/text to video: - runway does well for backgrounds with minimal movement (see below). for more complex scenes, there's weird morphing and distortion of objects - pika has the same issues as runway but is less obvious very excited to try out lumiere! 2024…

@matthew_j_l just started reading it a few days ago! I really like the idea of examining a system's high-level structure and inferring behaviour based solely on the patterns that those loops and arrows form -- reminds me a lot of graph theory & isomorphisms

I'm experimenting with this for cryptography; the goal is to reach 100% solve rate on CryptoHack. Starting with the RSA category: a few challenges need particular insights to exploit, but I'm quite confident in GPT-4's reasoning abilities here. cc @moyix

@lnofx similar to double vigenere cipher! you have two keys (melodies) of different fixed lengths that repeat in cycles to produce randomness. works best when lengths are relatively prime!

@moyix I’ve noticed GPT-4 is quite poor at general mathematical reasoning and gets caught up in irrelevant challenge details. That said, I think with the right system and agent behaviour we can solve most of these easier challenges
