offensive-supply-chain skillF

offensive-supply-chain is agent-read markdown (skill) from snailsploit/claude-red: Comprehensive offensive methodology for software supply chain attacks covering the full kill chain from reconnaissance through exploitation. Addresses dependency confusion across npm, PyPI, and NuGet ecosystems where internal registry override allows an attacker to inject malicious packages that shadow private dependencies. Covers typosquatting techniques for popular packages, compromised package injection via maintainer account takeover or social engineering, and build system attacks through Ma.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Offensive Supply Chain Attacks

Software supply chain attacks exploit the trust relationships between developers,
package registries, build systems, and deployment pipelines. You target the
components and processes that organizations depend on but rarely audit with the
same rigor as their own code. A single compromised dependency can propagate
across thousands of downstream consumers, making supply chain the highest
leverage attack surface in modern software ecosystems.

This skill covers the offensive lifecycle: reconnaissance of internal package
names, exploitation of registry resolution logic, build system hook abuse,
CI/CD pipeline tampering, and container image supply chain attacks. Every
technique maps to authorized red team engagement patterns with safe callback
mechanisms.

## Quick Workflow

1. Enumerate internal package names from target artifacts (lock files, source maps, error messages, GitHub repos).
2. Identify the package ecosystem (npm, PyPI, NuGet, Maven, Go, Ruby) and registry configuration.
3. Select attack vector: dependency confusion, typosquatting, build hook injection, CI/CD tampering, or container supply chain.
