What it detects
This rule detects creation or modification of AppCertDlls registry values, which load a specified DLL into any process that calls the Win32 process-creation APIs. Attackers abuse this key for stealthy code injection and persistence across newly spawned processes.
Reporting behind it
Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
