Flibustier: Why We Built a Container Security Auditor in Pure Bash

Short summary

Flibustier is a lightweight Bash container runtime security auditor designed for red team operations. It requires only Docker, jq, and standard UNIX utilities—no dependencies, compilation, or bulky Python environments. It audits for privileged containers, unsafe mounts, namespace misconfigurations, and other runtime vulnerabilities critical for detecting container escape risks.

• •Lightweight Bash tool for container runtime security auditing without external dependencies
• •Detects privileged containers, unsafe mounts, namespace sharing, and privilege escalation risks
• •Designed for minimal environments where Python, compilers, or package managers aren't available
