For the Love of the Game: DistrictCon's Year 1 Junkyard Notes from judging DistrictCon's Junkyard Year 1 — a Pwn2Own-style exploit contest targeting end-of-life devices. Disco balls, DNA sequencers, gym treadmills, and self-propagating game worms. Includes...

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/f...

screenshot of VSCode's integrated terminal auto-suggest

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

The Beast Opens its Eye: AI at LiveCTF 2025 In the most recent LiveCTF event, we witnessed a turning point: a player brought a custom AI bot that beat both human competitors to the punch… and in the two matches that the bot won, it wasn’t even ...

Finally ran my own experiment on 2 LiveCTF challenges after seeing an AI bot beat top players on them.

Granted, these are the 2 we saw AI solve, but I was still surprised by the success of current models with a single prompt.

Sharing so others can try it themselves: seeinglogic.com/posts/livect...

Team Atlanta's report explains how their CRS took first in AIxCC: team-atlanta.github.io/papers/TR-Te...

And you can just read the code! github.com/Team-Atlanta...

The report covers a ton: LLM usage, orchestration, and patching... but really shines in its coverage of practical fuzzing issues.

The #defcon hardcopy of @phrack.org is a thing of beauty!

As usual, the content has excellent technical depth & spirit... I really felt a connection reading Orange Tsai's musings on CTF and his role as a "bug archeologist."

Hats off to everyone involved; it will always have a spot on my bookshelf.

If you’re headed to DEF CON, don’t miss the AIxCC exhibit.

Not just to see me; though I’ll be there and at LiveCTF...

But to meet with some great minds in AI/cybersecurity space, and hear how the data from the competition will might drive a lot of future research.

But yes, also come by to see me!

Just got back from speaking at @summerc0n.bsky.social which was great 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! 😂

Extremely interesting comparisons in cybersecurity...

The 1️⃣ thing to focus on? Talent.

Talented people have outsize impacts in software and cybersecurity. And expertise drives better policy (eventually)!

Pipelines to build more experts pay compounding returns.

seeinglogic and zardus talk about getting into the cybersecurity industry YouTube video by pwn.college

Had a great time talking with @zardus.bsky.social about getting started in cybersecurity: www.youtube.com/watch?v=n9QW...

Primary thrust: Try something that interests you, then keep trying things.

Every time, you'll either succeed, learn something, or meet new people, and this builds over time.

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/runti...

Pattern in the Noise: Structured Fuzzing with Python “What happens if I need to fuzz something that doesn’t take strings or buffers as inputs” is the question I’ve come to dislike most when talking to people about fuzzing.

Wrapping up my posts on Python #fuzzing by going through different ways to generate structured/complex inputs: seeinglogic.com/posts/struct...

I focused on Python because there isn't as much written on it, but the concepts apply to any language and across tools!

Skip the hype, watch top CTF players for whether LLMs are changing the game (or not).

Exploitation of AIxCC Nginx bugs: Part I This blog post will analyse the exploitability of the temporal safety vulnerabilities in Nginx AIxCC. AIxCC is a DARPA competition to find vulnerabilities in codebases using AI. The competitors are no...

Enjoyed this deep-dive on attempting to exploit AIxCC's NGINX heap bugs: roundofthree.github.io/posts/nginx-...

Dense material, but enjoyed that they:
- Gave detailed allocator comparison
- Tried application-specific approaches
- Combined bug primitives
- Used a now-public vulnerability dataset!

Thanks for kind words, and thank you for reading!

It has been a minute since I wrote this, and you bring up a good point with LLMs being much more present in the coding environment now than when I wrote it. Maybe worth revisiting!

Heard a lot of people wondering how good RE//Verse
would be, and I can say...

It's been awesome.

Similar in vibe to Infiltrate and OffensiveCon, plus a super positive hosting crew.

Great talks so far, I'm biased but really liked @mahal0z.bsky.social 's on improving decompilation ⛵

What an amazing crew, everyone was great and a pleasure to work with.

Unbelievable resolve and effort... to run a con with the lights out!
