Logon Zero

This challenge documents the ZeroLogon vulnerability, which is a critical vulnerability originating from a cryptographic authentication protocol failure in Microsoft Active Directory. There is a ZeroLogon whitepaper, which is useful in solving this challenge. The underlying encryption scheme in both the challenge and the Microsoft Active Directory is the AES-CFB8. The encryption method should be clearly demonstrated in the paper. In the challenge, the encrypt method is not in use and only serve as a red herring....
