VIEW RULE IN DATADOG VIEW SIGNALS

Set up the 1password integration.

Goal

Detect when 1Password activity is observed from a Tor exit node.

Strategy

This rule monitors 1Password logs to determine when an activity 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 {{@usr.email}} from IP address {{@network.client.ip}} should have made the {{@evt.name}} API call.
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.
