performing-container-escape-detection
Detects container escape attempts by analyzing namespace configurations, privileged container checks, dangerous capability assignments, and host path mounts using the kubernetes Python client. Identifies CVE-2022-0492 style escapes via cgroup abuse. Use when auditing container security posture or investigating escape attempts.
Best use case
performing-container-escape-detection is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

# Performing Container Escape Detection
## When to Use
- When conducting security assessments that involve performing container escape detection
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
## Prerequisites
- Familiarity with container security concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities
## Instructions
Audit Kubernetes pods for container escape vectors including privileged mode,
dangerous capabilities, host namespace sharing, and writable hostPath mounts.
```python
from kubernetes import client, config
config.load_kube_config()
v1 = client.CoreV1Api()
pods = v1.list_pod_for_all_namespaces()
for pod in pods.items:
for container in pod.spec.containers:
sc = container.security_context
if sc and sc.privileged:
print(f"PRIVILEGED: {pod.metadata.namespace}/{pod.metadata.name}")
```
Key escape vectors:
1. Privileged containers (full host access)
2. CAP_SYS_ADMIN capability
3. Host PID/Network/IPC namespace sharing
4. Writable hostPath mounts to / or /etc
5. Docker socket mount (/var/run/docker.sock)
## Examples
```python
# Check for docker socket mounts
for vol in pod.spec.volumes or []:
if vol.host_path and "docker.sock" in (vol.host_path.path or ""):
print(f"Docker socket exposed: {pod.metadata.name}")
