Recommended defensive actions

  • Verify that deployed Ruijie Reyee OS instances are running version 2.320.x or later, or confirm with Ruijie that cloud-side mitigations are active for your environment.
  • Review cloud account access logs for unauthorized data access or exfiltration activity during the exposure window.
  • Audit sub-account permissions and remove unnecessary access to cloud management functions.
  • Apply network segmentation to limit cloud management interface exposure to authorized administrative hosts only.
  • Monitor for anomalous API calls or data retrieval patterns from Ruijie cloud services.
