VIEW RULE IN DATADOG VIEW SIGNALS

Goal

Detect when an attempt to create a high GPU-based virtual machine (VM) instance in OCI occurs.

Strategy

This rule monitors OCI Audit Logs to determine when an attempt to create an anomalous number of high 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

1. Determine if {{@usr.name}} should be creating the VM instances.
2. 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.
3. If the results of the triage indicate that an attacker has taken the action, begin your company’s incident response process and an investigation.
