/ Operation leveraging Terraform, Kubernetes, and AWS for data theft
The Sysdig Threat Research Team recently discovered a sophisticated cloud operation in a customer environment, dubbed SCARLETEEL, that resulted in stolen proprietary data. The attacker exploited a containerized workload and then leveraged it to perform privilege escalation into an AWS account in order to steal proprietary software and credentials. They also attempted to pivot using a Terraform state file to other connected AWS accounts to spread their reach throughout the organization..:
