Detect Supply Chain Compromise
Detection and response for supply-chain compromise: a poisoned software package or tampered build artifact that executes on install (MITRE ATT&CK T1195.002, T1546 for .pth / import-hook persistence, T1552 for credential stealers), and a trusted MSP or RMM platform turned into a delivery channel (T1199, T1543.003, T1572). Keyed off Linux file-creation telemetry (auditd, Sysmon for Linux, EDR) over site-packages, Windows System Event ID 7045, Windows process creation (Sysmon 1 / Security 4688), and package and container inventory. Ships two UMBRASEC sigma-pack rules plus a hunt, with tuning and Essential Eight / ISO 27001 / NIST CSF 2.0 mappings. Use when a dependency or Docker image you run was backdoored, triaging a PyPI, npm, or container supply-chain advisory, hunting a cook.pth import hook or dropped credential stealer, responding to an MSP or RMM compromise, or chasing an unexpected Cloudflared tunnel service.

From the source SKILL.md
Supply-chain compromise reaches you through something you already trust: a package you pulled from a registry, a container image you deployed, or the managed service provider that runs your fleet. The breach itself usually happens somewhere you cannot patch - an upstream maintainer account, a vendor build pipeline, an RMM console in your provider's rack - so the defensive win is not stopping the compromise upstream but catching what it drops on the hosts you do own. This skill is defensive: it explains the technique only as far as detection and mitigation require, and ships no…
What this skill does
Detect Supply Chain Compromise is a community-contributed Claude Code skill in the threat-hunting sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/detect-supply-chain-compromise/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a dependency or Docker image you run was backdoored, triaging a PyPI, npm, or container supply-chain advisory, hunting a cook.pth import hook or dropped credential stealer, responding to an MSP or RMM compromise, or chasing an unexpected Cloudflared tunnel service.
Who uses this skill
The Detect Supply Chain Compromise Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 211,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Detect Supply Chain Compromise skill?
Use Detect Supply Chain Compromise when your Claude Code task falls under the Security category — specifically in the threat hunting area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Detect Supply Chain Compromise" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Detect Supply Chain Compromise skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Detect Supply Chain Compromise is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
