• a temp encrypted cred issued by the Key Distribution Center (KDC) that acts as a master key or auth token that allows the user to request Ticket Granting Service (TGS) for specific network resources like a file server or application from the Ticket Granting Server with single sign on, improving security by storing this master key locally
  • TGTs have a limited lifetime
  • TGTs are encrypted with the user’s password
  • the KRBTGT account on a Domain Controller (DC) is responsible for creating and signing all TGTs with its own password hash
  • the TGT includes the session key used to make session ticket requests as part of its encrypted contents
    • since the TGT stores the session key, the KDC doesnt need to store it since it can just recover a copy by decrypting the TGT
  • stolen TGTs can lead to Pass The Ticket Attacks
