Goal
Detect when an attempt to create a GPU-based virtual machine (VM) instance in Google Compute Engine occurs.
Strategy
This rule monitors Google Cloud Audit Logs to determine when an attempt to create an anomalous number of GPU-based VM instances in Google Compute Engine has occurred. An attacker who has already gained initial access may try to create GPU-based VM instances with goal mining cryptocurrency.
Triage and response
- Reach out to the user or owner of the service account to determine if this action is legitimate.
- If the action is legitimate, consider including the user in a suppression list. See this article on Best practices for creating detection rules with Datadog Cloud SIEM for more information.
- Otherwise, use the Cloud SIEM - User Investigation dashboard to see if the user
{{@usr.id}} has taken other actions. - If the results of the triage indicate that an attacker has taken the action, begin your company’s incident response process and an investigation.
