Goal

Detect when Tor client activity is seen in AWS CloudTrail management plane logs.

Strategy

This rule monitors AWS CloudTrail management plane logs to determine when an activity had originated from a Tor client. Datadog enriches all ingested logs with expert-curated threat intelligence in real time. An attacker may use a Tor client to anonymize their true origin.

Triage and response

  1. Determine if the actions taken by the identity {{@userIdentity.arn}} are legitimate by looking at past activity and the type of API calls occurring.
  2. If the results of the triage indicate that an attacker has taken the action, begin your company’s incident response process and an investigation.
