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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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. …

How to install
mdr add miosa-osa/osa/offensive-supply-chain@sha256:9eb53a643d9076e4The line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
