Description
Objective: Recover the hidden real flag from the program, in the format `CMO{...}`. Platform: Windows x64, standalone console executable with no external dependencies. Input: A 16-character passphrase (`guessme.exe <passphrase>` or interactive input). Validation: The program prints the flag only if the passphrase is correct. Otherwise, it simply outputs `nope.` Hint: Running `guessme.exe --hint` displays a hint, but the hint may not be trustworthy. Difficulty: Intermediate. You need to understand an 8-round reversible transformation, bypass silent anti-debugging mechanisms, and realize that patching the conditional jump alone will not reveal the flag.
