Challenge Lore
During a routine security audit, you've discovered an abandoned terminal running a secure vault access system. The system appears to be protecting sensitive data, but the authentication mechanism has been heavily obfuscated by the previous administrators.
Your mission: Reverse engineer the authentication system and extract the vault contents. The system uses multi-layer obfuscation and anti-debugging measures, but static analysis should be sufficient to crack it.
Hint: Look for XOR operations and multiple valid access credentials.
