Live hacker versus hacker streams with commentary

i had the most fun with a ctf chall in a while with this defcon quals live ctf challenge

birds (def not bots) are machines made for shooting each other

[LiveCTF @livectf]

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 https://t.co/FDlcw7kiGT to find links to all the recap streams we did and witness the chaotic bird training action!

@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: https://t.co/bpWMum7Kx9

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: https://t.co/XNVBKbgGhH

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
