Semperis DSP Well-known privileged SIDs in sIDHistory
Id | ddd75d93-5b8b-4349-babe-c4e15343c5a3 |
Rulename | Semperis DSP Well-known privileged SIDs in sIDHistory |
Description | This indicator looks for security principals that contain specific SIDs of accounts from built-in privileged groups within their sIDHistory attribute. This would allow those security principals to have the same privileges as those privileged accounts, but in a way that is not obvious to monitor (e.g. through group membership). |
