What it detects

This rule flags Linux processes that establish network connections to known cryptocurrency mining pool hostnames, including Monero-related pools. Such connections are often used by unauthorized miners to retrieve work and submit mined shares, making outbound traffic to these domains a useful indicator of potential resource abuse. It relies on telemetry that records process-level network connections with a destination hostname match against the listed pool domains.
