    If you're getting into a career as an analyst/engineer at an infosec vendor, I recommend exploring/practicing with the following detection tech: Yara Snort/Sur Bro/Zeek Cuckoo ClamAV Though there are others, these are most prevalent and secretly power lots of detection techs.

    Any ideas for Masters/Bachelors thesis topics around malware analysis, reverse engineering, low-level security or other infosec topics? Please RT too - I get this question a lot and I always struggle to answer. So I hope to use our community's wisdom and send folks here :)

    I'm gonna start tweeting a bit about my experiences with starting treatment for ADHD. A lot of the reason for this is to make it easier for me to track my progress. I could do that privately, but then I'd miss out on others sharing their experiences. Not interested? Mute

    Just pushed a SEH module to ByePg, letting you use SEH in manual mapped drivers effectively bypassing another PatchGuard protected mechanism as it protects PsInvertedFunctionTable. System-call hooks coming Soon™.

    Someone asked me recently what's a boring topic that I'm excited/fascinated by. That's easy: cement. If it's wasn't thousands of years old, cement would seem futuristic. Think about it: it's *liquid rock*! Here's how it works:

    «Habla en Catalán y luego te dejamos pasar. Si no hablas catalán no pasas“ Esto no es democrático. Esto no es una protesta. Esto es puro autoritarismo de los años más oscuros de Europa.

    My note about Google Chrome and why I have decided not to throw its use - "Why Google Chrome runs so much processes". TL;DR It's about usability and security.
