ICYMI: 5 systems from AIxCC are now Open Source: archive.aicyberchallenge.com An unprecedented opportunity to peek into the toolkit of top security teams. Everything from prompt templates, to terraform code, to implementations of very recent research techniques, it's all there 👀
Phrack turns 40. The digital drop is live. Download it. Archive it. Pass it on. 💾 phrack.org #phrackat40 #phrack72
The #defcon hardcopy of @phrack is a thing of beauty! It embodies both technical depth & the hacker spirit (as usual). Reading @orange_8361's musings on CTF & his role as a bug archeologist was like recognizing an old friend. Thank you, Phrack staff, for making this treasure.
If you're not at #defcon right now and feeling some CTF FOMO, you can still tune in and watch the semifinal and final matches of LiveCTF at livectf.com Scroll down for a bracket with matches in your local time, and tune in!
Who's ready for hacker summer camp?! The LiveCTF team is excited to be joining @Nautilus_CTF again for DEF CON CTF finals starting tomorrow! Check out the schedule showing our streaming links and live bracket! livectf.com
If you’re headed to @defcon, don’t miss the AIxCC exhibit. Not just to see me (I’ll be there and at LiveCTF) But to hear about a competition that will become a huge dataset that will drive future research. Lots of heavy-hitter technical minds between the teams & everyone else.
Just got back from speaking at @SummerC0n, which was a ton of fun! They really have a unique vibe that's only possible from a small conference with a loyal following. Personally I appreciate the conference's sense of style and personality, and their meme game is impeccable! 😂
Verrrry interesting work... The takeaway of "need to invest in talent" rings true to me. All important cybersecurity impacts flow down from skilled people. I'd expect to see more investment in the pipeline for something that is so important to nations.

Had a great conversation on-stream with @Zardus on getting started in cybersecurity: youtube.com/watch?v=n9QWXZ… Major themes: 1. Start with what interests you and keep pursuing expertise 2. Try something different 3. Get out there and do something, you either succeed or you learn
Dear hacker Twitter: where do you buy hacker shirts?
There were some cool stuff demo'd last year (dance arcade game comes to mind), and that was just the first iteration! Can't wait to see what crazy stuff people bring this year.

Someone said to me recently "we're going to need people to babysit LLMs that do the work people used to do"... And my knee-jerk response was "I dunno, that sounds like a certain kind of hell to me." Apparently some folks are already testing the waters: github.com/dotnet/runtime…
We're thrilled to announce we're coming back for DistrictCon Year 1! 🗓️ Jan 24-25, 2026 📍Capitol Hilton
Wrapping up my series on Python #fuzzing by going through different ways to generate structured/complex inputs: seeinglogic.com/posts/structur… Looking forward to doing more fun viz work for dev/security... DM or reply if there's a topic you'd like to see come to life!
