We didn't really post here during the event but DEFCON CTF Quals just concluded and LiveCTF was part of it with a new concept. Check out our website livectf.com/ to find links to all the recap streams we did and witness the chaotic bird training action!

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/LiveCTF-…

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…

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
