Detection Methods for CVE-2023-29360

Indicators of Compromise

Unauthorized execution of system services
Unexpected elevation of privileges events in logs
New administrative command runs from unusual sources

Detection Strategies

Implement continuous monitoring of service changes, focusing on unusual service start/stops and privilege escalations in logs. Utilize endpoint detection capabilities to spot anomalous behaviors related to StreamService and associated processes.

Monitoring Recommendations

Deploy SentinelOne Singularity to monitor service executions and abnormal process behaviors. Use behavior-based AI to detect deviations reflecting exploitation attempts and privilege escalations.

How to Mitigate CVE-2023-29360
