Kerberoasting is an attack method that allows an attacker to crack the passwords of service accounts in Active Directory offline and without fear detections.
How it works kerberoast
- An attacker scans Active Directory for user accounts with specified SPN values using any methods, including PowerShell and LDAP queries; scripts provided by the Kerberoast toolkit or tools such as PowerSploit
- Once a list of target accounts is received, the attacker requests AD access to the service using SPN values
- Using Mimikatz, the attacker extracts the service requests in memory and stores the information in a archive
- Once the credentials are stored on disk, the attacker passes them to a password cracking script that will run a password dictionary as NTLM hashes with the requests of the exported service until the request can be successfully opened. When the request is finally opened, it will be presented to the attacker in clear text.
