Our team found a Poseidon hash collision in Solana's Agave VM crypto syscall.
Two distinct byte inputs → same field element → same Poseidon output. Affects both Agave and Firedancer via implicit padding paths.

🔥Introducing Arion🔥
A high-performance C++ framework for emulating executable binaries.
Based on Unicorn and inspired by Qiling, Arion offers an easy-to-use interface and super low execution times making it a great ally for fuzzing or other applications.

Just wrote a new blog post about rust symbol recovery, this time targeting cross-compiled targets !
Here is the blog post: nofix.re/posts/2024-23-05-ru…
I also updated rustbinsign/rustbininfo to identify and handle MinGW targets accordingly.

I just wrote a blog post and made a tool about my journey into recovering symbols from KrustyLoader, a malware written in rust @ektoplasma_ from @Synacktiv analyzed not long ago. Check it out if you are into rust reverse engineering ! 😁

Cerberus v1.2 is out ! The tool can now recover symbols of stripped Go binaries in addition to Rust. The rate is still of ~90%. 🔥I am open to any feedback🔥
