Multi-cloud data transfer attack path exploiting unauthenticated object storage sync jobs
Cloud Security

What does it take to break into a Cloud Service?

Sometimes, all it takes is cp and rsync. See the image below for an example.

Key takeaways
  • Automated cloud sync scripts often bypass perimeter controls and leak data into untrusted buckets.
  • Verify IAM roles and bucket policies on both source and destination before running rsync pipelines.
  • Unrestricted cloud-to-cloud copies are a primary mechanism for silent data exfiltration.
