What it detects

This rule detects the Cognitive Services ListKeys action in Azure activity logs, the API-key retrieval step Red Canary observed adversaries using to obtain persistent Azure OpenAI credentials. Because the returned key does not expire unless regenerated, unexpected ListKeys calls against a Cognitive Services account can indicate an actor acquiring durable access for later model abuse.
