What it detects

This rule detects curl downloading remote content directly into the AppData Local Temp directory, the ingress technique DarkGate uses to stage its AutoIt loader and encrypted payload. Fetching executables into user Temp via curl is uncommon for legitimate software. Combined with an HTTP source this suggests malware staging.
