What it detects

This rule identifies registry changes that register a monitor for silent process exit of lsass.exe under the SilentProcessExit key path. Attackers can use this technique to trigger actions on lsass.exe termination that may support memory dumping and credential access. It relies on Windows registry event telemetry matching TargetObject paths containing Microsoft\Windows NT\CurrentVersion\SilentProcessExit\lsass.exe.
