Checkout the Post-Mortem of our system ARTIPHISHELL (by @degrigis and I)! We look at a few issues that kept @shellphish from a top-3 spot in @DARPA’s AIxCC: support.shellphish.net/blog/2025/08/2… Keep your eyes out for more ARTIPHISHELL content in the future!
The second post in my AIxCC series is out. This one breaks down the rules and scoring—key to understanding why teams built their systems the way they did. It also analyzes teams results and why some of them found less vulns but were scored higher! algillera.substack.com/p/aixcc-series…

Back at Defcon after years away. The highlight? DARPA’s AI Cyber Challenge (AIxCC). It blew me away—and inspired me to launch a new personal blog. I'm doing a series of posts about AIxCC. The first one is out: algillera.substack.com/aixcc-series-i…

Is there any playlist with the songs played between talks at @BlackHatEvents. They are soooo cool!
Really cool talk at Blackhat to train models on a specific task, in this case malware development bypassing AVS. Single purpose model are way better than general ones. Model was released: outflank.nl/blog/2025/08/0…

One of my all-time favorite type of videos is pre-fame bands playing their extremely famous songs to a tiny room of people, because they're not yet known. A thread of some examples: Bastille playing Pompeii in what looks like someone's living room:

Recently I was targeted by an extremely sophisticated phishing attack, and I want to highlight it here. It exploits a vulnerability in Google's infrastructure, and given their refusal to fix it, we're likely to see it a lot more. Here's the email I got:
