Got 1st place in defcon quals. It's time to accept the power of AI.
While I was grinding on shellcode minimization, my teammate's AI found better solutions. Once I accepted that and started guiding the AI, it eventually found the best score.
In optimization-heavy competitions like KOTH, which push us beyond human limits and require intuition and creativity, I used to believe that humans could still outperform AI.
I got beaten by AI.

The core utilities that run every Linux system have been rewritten in Rust. We audited them.
Before shipping uutils coreutils with Ubuntu 26.04, @Canonical commissioned Zellic for an external security audit.
Two rounds, fixes contributed directly upstream.
Full report below.

If you've ever used @LineaBuild bridge on @okx Web3, Make sure to REVOKE approvals immediately on revoke.cash. The contracts are 0xd19d4B5d358258f05D7B411E21A1460D11B0876F on Ethereum, 0x508ca82df566dcd1b0de8296e70a96332cd644ec on Linea.
When I queried approvals on-chain, there are many victims on Ethereum, but only few victims on Linea.
