CDK

CDK (Container penetration toolkit) is an open-source tool designed for container environment penetration testing and exploitation. It's distributed as a single static binary with zero dependencies, making it easy to deploy inside target containers during red team engagements. CDK bundles three categories of functionality: evaluation (gathering container environment information, checking capabilities, and identifying potential escape vectors), exploitation (automated container escape using techniques like mounting host filesystems, exploiting Docker socket, abusing Linux capabilities, and leveraging kernel vulnerabilities), and tools (network scanning, file transfer, reverse shell, and other post-exploitation utilities). CDK is regularly updated with new escape techniques as they're discovered, making it the most comprehensive container escape toolkit available.
