  1. Challenge

    Getting Started in the Lab Environment

    Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

  2. Challenge

    Enumerating Service Principal Names

    Globomantic's service accounts may have SPNs vulnerable to Kerberoasting. Using Rubeus, your task is to enumerate the service accounts in the Active Directory environment that have SPNs associated with them.

  3. Challenge

    Obtaining the Service Ticket

    Now that you've identified service accounts with SPNs, your next task is to obtain the service tickets associated with these accounts. These tickets will later be cracked to reveal plaintext credentials.

  4. Challenge

    Cracking the Kerberos Ticket with John The Ripper

    With the service tickets hashes in hand, it's time to crack them. Your colleague has prepared a wordlist for use with John the Ripper. You will now crack the tickets to recover plaintext passwords of service accounts.

  5. Challenge

    The Last Challenge

    Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
