Goal

Detect when a host is potentially infected with a cryptominer.

Strategy

This rule compares the @network.client.ip standard attribute to a curated list of cryptomining pools.

Triage and response

Determine if the {{host}} host should be contacting a cryptomining pool.
If not, begin your company’s IR process.

Note You can use the signal sidepanel to assist with the initial investigation by looking at CPU utilization and processes to identify unauthorized activity.
