Earlier this year, I used a 1day to exploit the kernelCTF VRP LTS instance. I then used the same bug to write a universal exploit that worked against up-to-date mainstream distros for approximately 2 months. osec.io/blog/2024-11-2…

We are back😎 Say hello to our kernelCTF submission for CVE-2025-37752🩸 Who would have thought you could pwn a kernel with just a 0x0000 written 262636 bytes out of bounds? Read the full writeup at: syst3mfailure.io/two-bytes-of-m… 👀

🚨🚨🚨We just broke everyone’s favorite CTF PoW🚨🚨🚨 Our teammate managed to achieve a 20x SPEEDUP on kctf pow through AVX512 on Zen 5. Full details here: anemato.de/blog/kctf-vdf The Sloth VDF is dead😵 This is why kernelCTF no longer has PoW!

Oops, we just pwned the kernelCTF mitigation instance with a 0day😳 Our fellow pwner syst3mfailure has picked up pigeon feeding as a hobby to help him cope with the insanity
