Shows concrete exploits: a return‑oriented programming demo that hijacks control flow with GDB, a printf format‑string leak that reveals remote environment variables and the flag, an image EXIF payload that makes PHP execute code, and a cookie deserialization RCE via node-serialize. Uses Ghidra and pwntools for reverse engineering and automation, runs on Kali/WSL and netcat for callbacks. Builds company CTFs that work — one attacker redeems 73 cinnamon‑bun prizes, legal deletes a DB during practice.
