I'm optimistic we can create _some_ type of knowledge-based security-related community activity but traditional online jeopardy-style CTF as a competitive format is on its deathbed and this video hurts. Big love to the community that has meant the world to me the past 11 years!

Junkyard was an absolute pleasure to host again, it was awesome to see it take off... we even had a Roller Coaster Tycoon exploit this year!
In case you missed the show, @caseyjohnellis gave a great writeup of the EOL targets and exploits shared: cje.io/2026/02/07/for-the-lo…

VSCode has leaned forward on a lot of fantastic usability enhancements...
But their recent "terminal autocomplete suggestion" setting has definitely been a mixed bag for me (distracting and suggests bad completions).
To disable: settings > "terminal suggest" and uncheck

Finally ran my own experiment with AI on LiveCTF challenges after seeing a bot beat top players.
…and I was surprised by the success of current models with a single prompt.
Sharing what I did so you can try it yourself: seeinglogic.com/posts/livect…

A friend told me I buried the lead, and that they felt this chart tells the tale.
While the sample size is very small, the data does not favor humans given the specific parameters of LiveCTF (average human solve 22.8 min).

Team Atlanta's report explains how their 1st place CRS found & patched bugs... and you can just read the code! github.com/Team-Atlanta/aixc…
The report covers a ton: orchestration, LLM strategies, patch generation... but really shines in its coverage of practical fuzzing issues.

Awesome linear probe based hallucination detection. Code and paper in thread.

Imagine if ChatGPT highlighted every word it wasn't sure about.
We built a streaming hallucination detector that flags hallucinations in real-time.

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 👀

My biggest surprise at #defcon33 : in a head-to-head LiveCTF match, one player’s AI bot beat _both_ humans to the punch.
I was commentating the match & was super confused because I could see the player had only just begun their solve script: youtube.com/live/TYn38VfmDRU…

But:
- These were non-trivial challenges that required synthesis of multiple concepts (PNG format, internal structure offsets, shellcode)
- The player provided almost no input at all, other than the challenge binary and presumably info on the LiveCTF format & challenge category

As the organizers of LiveCTF, we allowed for this possibility as an open challenge, but we were all surprised by this.
Perhaps a small turning point, but it marks a change in #CTF. Whether by policy or technical solutions, organizers will need to handle AI solvers.
