What it detects

This rule detects interaction with the Docker unix socket to create a privileged container, a container-escape technique highlighted in the BrokenSesame research. Access to the mounted docker.sock lets an attacker launch a privileged container that mounts the host filesystem. This combination indicates an attempt to break isolation and reach the node.
