What it detects

This rule detects HTTP requests to the /prrq.php proxy endpoint used by DeadLock ransomware to reach C2 proxy servers whose addresses are rotated through Polygon smart contracts per Group-IB. Adversaries route control and ransom-negotiation traffic through these proxy PHP endpoints, so requests to this path signal DeadLock C2 activity.
