What it detects

This rule flags changes to the Windows registry path under Explorer\TypedPaths\ within the user or admin registry hive, when the modifying process is not explorer.exe or SysWOW64\explorer.exe. Altering TypedPaths can help an attacker influence how Explorer resolves or displays typed path history, which may support persistence or related user-environment manipulation. It relies on telemetry that captures registry_set events, including the TargetObject path and the process Image that performed the modification.

Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
