Goal
Attackers often use compromised cloud infrastructure to mine cryptocurrency.
Strategy
Detect when a process performs a DNS lookup for a domain related to cryptomining.
Triage and response
{{@process.executable.name}} performed a DNS lookup for {{@dns.question.name}}
Note: Cryptocurrency mining is often a symptom of a greater issue. It is imperative to determine the initial entry point such as through compromised cloud credentials or an application that is vulnerable to remote code execution (RCE).
- Isolate the host or container and roll back to a known secure configuration.
- Use host metrics to verify that cryptocurrency mining is taking place. This will be indicated by an increase in CPU usage.
- Review the process tree, related signals, and related logs to determine the initial entry point.
Requires Agent version 7.36 or later
