Our talk with @stokfredrik.bsky.social about bitflips in the modern day and crazy results of our research was accepted to #why2025 !

It’s called ”Flipping Bits: Your credentials are certainly mine”. Come and see your favorite black metal band on the stage there ;)

Three Trail of Bits engineers audited core Go cryptography for a month and found only one low-sev security issue... in unsupported Go+BoringCrypto! 🍾

Years of efforts on testing, limiting complexity, safe APIs, and readability have paid off! ✨

Yes I am taking a victory lap. No I am not sorry. 🏆
Go Cryptography Security Audit
Go's cryptography libraries underwent an audit by Trail of Bits. Read more about the scope and results.

Exhausted? Maybe even some signs of hangover? Event post-blues after saying goodbye to all the wonderful people? Believe us, we are going through those too. Thank you all again and see you next year! ❤️

I've released 'brainstorm': an alternative way to do web fuzzing combining my fav fuzzing tool 'ffuf' (from @joohoi.bsky.social )with local LLMs (via Ollama API) to generate smarter filename tests. It usually finds more endpoints with fewer requests. Added a IIS shortname support @irsdl.bsky.social
