What it detects

This rule detects a Salesforce OAuth authorization for a connected app based on the Data Loader followed by API access from anonymizing VPN egress, matching UNC6040 abuse of a stolen app token to pivot across SaaS platforms. Granting this token lets the actor read and export data and pivot into Okta and Entra from the same infrastructure.
