@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? 🧵

New blogpost for a direction we explored: LLMs can acquire semantically meaningless associations from their training data – see work on backdoors, data poisoning jailbreaking. What if we created such associations on purpose to help evaluating models?

Zelensky is a wartime leader watching his people suffer and die under Russian attacks every day. To be lectured and lied to by Trump and Vance, as they defend the war criminal dictator committing these atrocities, is unimaginable agony. An everlasting shame for America.

There has never been anything like this. Trump and Vance look like children talking about accommodating Putin. Zelensky holds his ground and defends his nation… and the free world.

New writeup from @_specters_ and I: we're finally allowed to disclose a vulnerability reported to Kia which would've allowed an attacker to remotely control almost all vehicles made after 2013 using only the license plate. Full disclosure: samcurry.net/hacking-kia

I'm excited to announce a new decompilation control flow structuring algorithm, SAILR, which is the first to precisely revert compiler optimizations in decompilation. Find out how in our USENIX 2024 paper: zionbasque.com/files/publicat…. Code, info, and links in the 🧵

These posts on using clever tricks to automatically generate really fast interpreters and baseline JITs from simple C++ functions is really neat. It's like Truffle/Graal but way simpler: sillycross.github.io/2022/11/22/202…

A new day, a new blog post about breaking #dotnet decompilers with #cil. This time, we push the CALLVIRT instruction to the limits, and use it to invoke methods we should not be able to invoke in the first place :). washi.dev/blog/posts/con…
