Kerberoasting is an attack method that allows an attacker to crack passwords access of service accounts in Active Directory offline and without fear of detection.
How it works kerberoast
- An attacker scans the Active Directory directory service for user accounts with specified SPN values, using any methods, including PowerShell and LDAP queries, scripts provided by the Kerberoast toolbox, 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 it Mimikatz, the attacker extracts the service requests in memory and stores the information in a file
- Once the credentials are saved to disk, the attacker passes them to a password-breaking script that will run a password dictionary as the NTLM hashes with the exported service requests until the request can be successfully opened. When the request is finally opened, it will be presented to the attacker in clear text.
