Comprehensive and Detailed 100to 150 words of Explanation From AWS Certified Security – Specialty topics:

Cryptocurrency mining validation requires evidence of actual mining behavior, not only metadata about the finding. Process details show whether mining binaries or suspicious processes are running on the instance. DNS analysis can reveal lookups to known mining pools or suspicious domains. VPC Flow Logs help confirm outbound connections, destinations, ports, and traffic volume from the instance. GuardDuty uses foundational data sources such as DNS logs, VPC Flow Logs, and CloudTrail events to detect suspicious activity, so those same sources are appropriate for validating and scoping the finding. CPU metrics alone are useful context but not enough. Counting findings or checking severity does not prove impact. Session history and Route 53 records do not directly validate mining behavior.
