Important Windows Service Terminated Unexpectedly

Sigma Rules

View Source
Summary
This detection rule aims to identify unexpected terminations of important Windows services, specifically targeting events logged by the Service Control Manager. It focuses on Event ID 7034, which indicates that a service has exited unexpectedly. The selection criteria utilize multiple parameters to catch relevant services, including those related to Message Queuing and certain binary signatures that characterize particular services. The rule is set at a high alert level due to the potential implications of unauthorized service termination, which might indicate an ongoing attack such as defense evasion tactics or malware activity. The detection is contingent on the detection of specific events logged in the Windows system, ensuring that actionable alerts are generated when these specific conditions are met. However, it is important to note that some rare false positives may arise due to legitimate reasons for service terminations.
