1# Analyzing Docker Container Forensics
2 
3## When to Use
4- When investigating a compromised Docker container or container host
5- For analyzing malicious Docker images pulled from registries
6- During incident response involving containerized application breaches
7- When examining container escape attempts or privilege escalation
8- For auditing container configurations and identifying misconfigurations
9 
10## Prerequisites
11- Docker CLI access on the forensic workstation
12- Access to the Docker host file system (forensic image or live)
13- Understanding of Docker layered file system (overlay2, aufs)
14- dive, docker-explorer, or container-diff for image analysis
15- Knowledge of Docker daemon configuration and socket security
16- Trivy or Grype for vulnerability scanning of container images

18## Workflow

20### Step 1: Preserve Container State and Evidence
21 
22```bash
23# List all containers (including stopped)
24docker ps -a --no-trunc > /cases/case-2024-001/docker/container_list.txt
25 
26# Inspect the compromised container
27CONTAINER_ID="abc123def456"
28docker inspect $CONTAINER_ID > /cases/case-2024-001/docker/container_inspect.json
29 
30# Export container filesystem as tarball (preserves current state)
31docker export $CONTAINER_ID > /cases/case-2024-001/docker/container_export.tar
32 
33# Create an image from the container's current state
34docker commit $CONTAINER_ID forensic-evidence:case-2024-001
35docker save forensic-evidence:case-2024-001 > /cases/case-2024-001/docker/container_image.tar
36 
37# Capture container logs
