What it detects

This rule detects a scheduled task creation that masquerades as a Microsoft Edge update task while pointing its action at an executable under the temp directory which the SpiceRAT loader uses for persistence. A legitimate-looking update task name paired with a temp path payload is a strong masquerading plus persistence signal.
