VIEW RULE IN DATADOG VIEW SIGNALS

Goal

Detect when Tor client activity is seen in Google Cloud Audit Logs.

Strategy

This rule monitors Google Cloud Audit 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. Investigate other activities performed by the identity {{@usr.id}} using the Cloud SIEM - User Investigation dashboard.
2. If the results of the triage indicate that an attacker had taken the action, begin your company’s incident response process and an investigation.
