Kerberoasting
“Kerberoasting” is a security attack that targets the Kerberos authentication protocol used in Active Directory environments. In simple terms, in an Active Directory environment, Kerberos is one of several protocols that helps users and systems authenticate themselves securely. Kerberos is a Ticket Based system. Basically, Kerberoasting is a method where an attacker captures encrypted service tickets, targeting service accounts in an Active Directory environment, and then attempts to crack the encrypted information offline to reveal the service account's password.
