Cross-SaaS AI Agent Data Aggregation Followed by External Browse/Egress (Enter-Evade-Escape)
This rule detects potential data exfiltration by monitoring for anomalous user behavior across integrated SaaS applications. It flags accounts that perform high-frequency read, search, or view activities across three or more monitored SaaS platforms (Confluence, Jira, Slack, Google Workspace, Microsoft 365, or Bitbucket) within a 5-minute window, followed immediately by an upload or post activity to an external, non-integrated domain.
