Round 2 — "Reverse & Recover" (.exe Reversing) (Intermediate)

Goal: Reverse-engineer safe Windows executables to extract or reconstruct a flag.

Tasks: Extract embedded flags · Recreate algorithm logic · Patch binary to reveal flag (advanced).

Tools: IDA Free, Ghidra, radare2, x64dbg, strings, binwalk.

Scoring: Up to 60 pts (incl. bonus for automation). Time limit 2–3 hours.
