Ever wondered how some cli flag in ffuf works? I just rewrote the whole ffuf documentation, and one of the ways to browse it is through cli flag reference. Check them out: github.com/ffuf/ffuf/wi...

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. 🏆

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

Suddenly a lot of activity in the BlueSky. Sweet! Let’s give this another spin. Currently enjoying Ekoparty in Buenos Aires with @stokfredrik.bsky.social and @tomnomnom.com . Delivered a ffuf talk yesterday and now prepping for our bitflip talk tomorrow. It has, and will continue to be epic!
