Summary: Static analysis writeup — no execution required. The binary is a custom packer embedding an encrypted crackme in its PE overlay. Encryption: XOR with a 16-byte key + ROL8(3), key stored in a DEADC0DE/DEADBEEF trailer. Writeup covers the full process: triage, trailer parsing, algorithm recovery, decryption verification, and password extraction from the inner PE. Includes a Python solver that automates the entire pipeline.
