Overview

Supply chain attacks bypass traditional code review by compromising upstream dependencies. This skill provides patterns for detecting, preventing, and responding to compromised packages in Python ecosystems.

When To Use

After a supply chain advisory is published
When auditing dependencies for a new or existing project
During incident response for a suspected compromise
When adding the SessionStart hook to a project

When NOT To Use

General CVE triage unrelated to dependency supply chain
Application-level vulnerability scanning (use a SAST tool)
License compliance audits (different concern)

Known-Bad Versions Blocklist

The blocklist is at ${CLAUDE_SKILL_DIR}/known-bad-versions.json. It is consumed by:

SessionStart hook: warns per-session when compromised versions detected
make supply-chain-scan: CI/local scanning target
This skill: manual audit guidance

Blocklist Format

{
  "package_name": [{
    "versions": ["x.y.z"],
    "date": "YYYY-MM-DD",
    "description": "What the attack did",
    "indicators": ["files or patterns to search for"],
