Description

Welcome to the Chaos VM. This isn't your standard crackme. I've implemented a custom Virtual Machine where the instruction set is randomized (seeded). There are no clear text strings to grep for logic, and the control flow is entirely virtualized. Your Mission: Reverse engineer the VM to figure out the instruction mapping (what byte does what) and write a bytecode program that controls the VM to output the target string: SUCCESS_VM_1337. Input Format: Pass your bytecode as a comma-separated hex string argument. Example: InsaneCrackme.exe 01,AF,2B,CC... Warning: If your bytecode is invalid or fails to produce the correct output, you will be greeted with a (fake) Blue Screen of Death.
