Description
A user specifically requested weak and deprecated encryption in a Kerberos TGS request. This provides easy-to-crack hashes, and is typically a sign of a Kerberoasting attack.
Attacker's Goals
Crack account credentials by obtaining an easy-to-crack Kerberos ticket.
Investigative actions
Check who used the host at the time of the alert, to rule out a benign service or tool requesting weak Kerberos encryption.
