Mapped every skill to NIST CSF 2.0 subcategory IDs (GV/ID/PR/DE/RS/RC functions) based on subdomain and content analysis. Restores 11 skills corrupted during prior rebase, re-enriching with ATLAS, D3FEND, NIST AI RMF, and CSF 2.0 fields. All 754 skills now carry structured mappings for all 5 security frameworks: - MITRE ATT&CK (in tags) - MITRE ATLAS v5.5 (atlas_techniques) - MITRE D3FEND v1.3 (d3fend_techniques) - NIST AI RMF 1.0 (nist_ai_rmf) - NIST CSF 2.0 (nist_csf)

| 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. | cybersecurity | container-security |

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.
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:
- Privileged containers (full host access)
- CAP_SYS_ADMIN capability
- Host PID/Network/IPC namespace sharing
- Writable hostPath mounts to / or /etc
- Docker socket mount (/var/run/docker.sock)
Examples
# 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}")
