What it detects

This rule detects Rubeus command-line actions such as kerberoast, asreproast and tgtdeleg, which request and extract Kerberos tickets for offline cracking or impersonation. Rubeus-driven Kerberos abuse is a credential-access technique tracked in the Red Canary Threat Detection Report. Detecting these actions surfaces ticket theft aimed at privilege escalation.
