What it detects

This rule detects ITG05 Headlace retrieving staged payloads from the mocky and mockbin request-mocking services used as disposable command-and-control. Requests to these API-mocking hosts from enterprise endpoints are unusual and warrant review. The services return next-stage scripts to the infection chain.
