5 stages of hacking: - This is impossible. - Why am I even doing this? - Wait... what if I try this? - holy sh*t it worked - I am a genius.
@theori_io's AIxCC CRS has already found dozens of 0day vulnerabilities, and we've barely scratched the surface! The best part: it's open source, so there's no secrets to hide (at least in the AIxCC version 😉)! So, how does our CRS actually find these 0days? 🧵
The @AptosLabs and @osec_io team teamed up to create a set of Move challenges for @AppSec_Village, and one of them even won the Best Challenge Award! If you attempted or solved any of our challenges and have questions, feel free to DM me. Happy to chat! /cc @zi0Black @FetchDEX
