What it detects

This rule detects creation of a scheduled task whose action points to an executable inside the user AppData directory. Nokoyawa-linked loaders register an hourly task in AppData Roaming to maintain persistence for IcedID and follow-on tooling. Scheduled tasks launching binaries from AppData are unusual and a common persistence mechanism for commodity loaders.
