What it detects

This rule detects a privileged Docker container being started with the host root filesystem bind-mounted into it, a configuration used to break container isolation and read host secrets. It is associated with software supply chain attacks that abuse developer and CI Docker access to reach host credentials. Detecting privileged host-mount launches flags container escape and credential access attempts.
