Task: multi-step web challenge on a Node/Express 'BugOS' app — keyboard-layout password reminder, PNG LSB stego, ZipCrypto-protected archive, and an IDOR over md5-named launch logs. Solution: RU/EN layout swap to recover the login password, RGB-interleaved LSB to read the rockyou hint, a custom ZipCrypto cracker that uses the DOS-modtime high byte as the check byte (because the data-descriptor bit is set), and md5(sequential-id) log enumeration to recover the historical successful launch parameters.
