Description

if you somehow manage to crack this add @humblenes on discord, im genuinely curious how you got around a custom packer, bonus points if you dont open it in x64dbg (ignore the .pdb file name in there :sob:)

niko122 on 2026-02-27 19:47: @msym yeah its much harder in ida then in x64dbg but this was just a test to see how well the first version of my thingy works it has no protections at all, i just added anti debugging and integrity checks im probably going to add wayyy more stuff but thats in the future!

msym on 2026-02-28 01:32: @niko122 Looking forward to your next version :)

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.
