What it detects

This rule detects HTTP requests carrying the hardcoded User-Agent value IOT together with POST requests to the /iot/post URI, the reverse shell beaconing pattern of the UPDTAE backdoor deployed by the Quad7 operators. The implant polls its C2 roughly every thirty seconds using this fixed header and path. The unusual static User-Agent and endpoint make this a reliable network indicator.
