What it detects
This rule detects use of the deprecated at.exe utility to schedule jobs. Modern Windows administration relies on schtasks, so at.exe execution is uncommon and often tied to adversary persistence or lateral movement. Its rarity in legitimate use makes it a useful hunting signal.

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