LiveCTF

@richinseattle @thegrugq In this year's @livectf, the player from Blue Water had built a fully autonomous AI agent which solved the challs in the background. It solved 3 of the challs he played, but a lot of them are probably AI solvable. They (+link to stream) can be found here: github.com/Live-CTF/LiveC…

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/TYn38VfmD… 🧵👇

looks like the AI + MCP-assisted reverse engineering hype train is gaining steam! 🚂✨ in just the past few days, we've seen: • @itszn13 integrating MCP into @vector35’s Binary Ninja (x.com/itszn13/status…) • @JH_Pointer casually dropping his IDA MCP project, which I had to nerdsnipe myself into trying (github.com/MxIris-Reverse…, x.com/bl4sty/status/…) • @mrexodia rolling out a clean (judging by a quick code quality check) MCP implementation for IDA (github.com/mrexodia/ida-p…) • @lauriewired dropping GhidraMCP for @NSAGov’s Ghidra (github.com/LaurieWired/Gh…) these tools are early-stage but already hint at the potential for interactive RE software running on (semi) autopilot. makes me wonder—should we formalize a set of MCP primitives across RE tools and unify them under one overarching framework? 🤔 of course, these aren’t silver bullets. but much like typical LLM usage, in the right hands, they could be powerful time-savers. curious to see what comes next! might be time for hacking competitions focused on small/constrained binaries to start thinking about countermeasures against AI-assisted cheesing. 👀

We might have gotten a bit pre-occupied with running the event itself instead of posting, but we wrapped up the LiveCTF finals during DEF CON CTF! Final results and links to all three days worth of videos: livectf.com Oh, and also: github.com/Live-CTF/LiveC…

Join us in 15m for the second stream of the weekend! Let's talk about the solutions to our first challenge. youtube.com/live/1yULJ7g21…

Did you miss us? LiveCTF is back! Join us this weekend during the DEF CON CTF Qualifiers by @Nautilus_CTF: nautilus.institute We'll post updated details on our website soon, but you can expect the same structure as quals last year.

Check out some cool analysis of a pwnable speed solve from this year's LiveCTF by one of our crew members!

The Google CTF Finals 2023 are coming! Watch the best CTF teams compete in our custom video game tomorrow, Sunday, 1pm JST. #Hackceler8 #GoogleCTF #Gaming

In the final round of @livectf at Defcon this year, the contestants hit sudden death when both of their Noppenheimer solutions solved locally but failed to land remotely. You can solve this all too-common CTF problem with some scapy IP fragmentation supernetworks.org/pages/blog/sca…

@LiveOverflow has fantastic videos: youtu.be/L2C8rVO2lAg?si… There’s also pwnable.kr and pwnable.tw And you can watch real CTF players go head to head with @livectf

Who else are we missing? If your team participated in LiveCTF, let us know individual contributor info (if they wish to be identified) so we can update match descriptions. We just updated all the @mhackeroni matches with Chino's info (twitter.com/Kee__no). Tell us yours!

@jduck @defcon @vector35 @psifertex @negasaur @gamozolabs @mdowd Glad you enjoyed it! We try to make something that's both educational and entertaining. We have published all the challenges and the solve times for the players so you can have a go: github.com/Live-CTF/LiveC…

Enjoyed the @defcon @livectf! Great commentating from @vector35 @psifertex, Carl, Mark, @negasaur @gamozolabs. Can't help but feel like I could beat the contestants (probably wrong). That comment about the best hackers in the world... Not so sure. @mdowd wasn't even in Vegas.
