What it detects

This rule detects a Run key autostart entry that launches the Node.js interpreter against a JavaScript payload. This behavior is tied to the MuddyWater APT Tsundere botnet which resolves its command and control from an Ethereum smart contract using EtherHiding. Persisting node.exe via the Run key lets the operator survive reboots and maintain WebSocket beaconing.
