What it detects

This rule detects quser or qwinsta enumerating interactive logon sessions, a system-owner and remote-session discovery step attackers use to find active administrators before lateral movement. Session discovery is tracked in the Red Canary Threat Detection Report. Detecting these queries surfaces reconnaissance of who is logged on.
