Description

An identity created a Kubernetes pod with the host process ID (PID) namespace. This may indicate an adversary attempting to access processes running on the host, which could allow escalating privileges to root.

Attacker's Goals

• View processes on the host.
• View the environment variables for each pod on the host.
• View the file descriptors for each pod on the host.
• Kill processes on the node.

Investigative actions

• Check the identity's role designation in the organization.
• Inspect for any additional suspicious activities inside the Kubernetes Pod.

Variations
