Break weak schemes, exploit implementation flaws, and recover plaintext that was never supposed to come back.
Read a binary the way its author never intended you to — disassemble, debug, and rebuild its logic in your head.
Corrupt memory on purpose. Bypass modern mitigations and turn a bug into arbitrary code execution.
Reconstruct an intrusion after the fact from memory dumps, disk images, and packet captures.
Pull scattered public data into a coherent picture — the reconnaissance phase of every real engagement.
