Description

Goal ---- Find a valid name + serial (or write a keygen) that prints "Good boy!" and the flag. Do not use patching as it is not an intended solution. How to run ---------- AbyssCrackme_v1.exe AbyssCrackme_v1.exe <name> <serial> Protection notes (not covered by labels) ------------------------------------------------- - uses a custom packer named abyss that I'm currently working on - string encryption uses compile-time Feistel - crypto: custom stream cipher (pack + SMC), not a listed string-crypto algo - serial/name algo: custom mix/hash (not MD5/SHA/AES/RSA) the program is heavily obfuscated and packed, which can lead to false positives from antivirus software (expected at this level of difficulty) Author: kwsl
