What it detects

This rule identifies Windows process executions whose command line references the VSS diagnostics service and includes the switch to disable snapshots. Attackers may impair backup and recovery capabilities by turning off Volume Shadow Copy, reducing defenders’ ability to restore data. The detection relies on process creation telemetry and matches specific command-line substrings indicating the targeted VSS component and the disable action.
