Windows New Service Security Descriptor Set Via Sc.EXE — Detection Rule
The following analytic detects changes in a service security descriptor. It leverages data from Endpoint Detection and Response (EDR) agents, specifically searching for any process execution involving the "sc.exe" binary with the "sdset" flag targeting any service. This behavior can be legitimate, such as when a user or administrator is configuring a service's security settings. Investigate appropariate services to determine if the behavior is malicious. If confirmed malicious, this could allow an attacker to escalate their privileges, blind defenses and more.
