Description
I'm hoping that I didn't forget anything else (like making the seed immediate operand xd). Genesis is the better Ouroboros. While its surface-level purpose remains scanning and sanitizing sensitive strings from process memory, its internal architecture has been rewritten into a multi-layered protection system. What's New? You may ask: The previous version had several flaws, including predictable serial logic and global state leaks that allowed it to get solved quickly. Genesis now has: Polymorphic Meta-VM: The core logic is virtualized. An "Outer VM" decrypts and dispatches instructions to an "Inner VM" using session-unique, randomized opcode mappings. JIT Machine Code Generator: Serial verification code does not exist in the binary. It is generated in memory at runtime, executed, and wiped. Instruction-Level SMC: Using a custom VEH dispatcher, the program single-steps through critical code, re-encrypting the previous instruction and decrypting the next one in a sliding window. Heisenberg Logic: A stealthy anti-debug mechanism. Detecting a debugger silently corrupts the mathematical session seed instead of crashing, leading analysts into a rabbit hole. Ultimate Hardening: All critical states are stored in a Self-Decrypting Secure Context. JIT targets are hidden in non-executable "Data Slots" resolved via exceptions. The seed is machine-independent but session-unique. The Goal: Solve the Ouroboros Handshake: Find the relationship between the Session Seed and the required Serial. Dump the Core: Provide a clean, de-virtualized dump of the ScanAndWipe routine. Warning: Aggressive exception-based control flow. It will crash unstable debuggers. Contains NO malware. All techniques are for educational security research.
