InCTF Finals 2026


CTF Conducted by Team BIOS.

Participated under Flagsomnia

Airgapped no-ai CTF. Had a lot of fun with pwn and rev challenges (very glad that I learned angr and z3 a couple weeks before)

2x Pwn, 3x REV, ~5000 points, position #3 in India.

Rev Adulthood

Interesting Z3 rev challenge. Solved it with power of unix tools, vim and ofc, some Z3. (Possible Unintended Solution :))))

Rev Enigma

Why bruteforce when you can just angr your way out of rev challenges. (+ firstblood)

Rev Darthvader

Why Z3 when you can have to just bruteforce ~256 possiblities

Pwn Batman

Simple SROP FTW. Write “/bin/sh\x00” to .bss and execve.
