Use when attacking or auditing a CI/CD pipeline or software supply chain — pwn requests, poisoned pipeline execution, compromised/mutable-tag actions, dependency confusion, registry worms, runner backdoors, OIDC trust abuse, SLSA/provenance.
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
# CI/CD Pipeline Poisoning & Supply-Chain Attacks
## When to Activate
- Auditing or attacking GitHub Actions / GitLab CI / Jenkins pipelines for code execution
- Hunting `pull_request_target` / `workflow_run` "pwn requests" and Poisoned Pipeline Execution (PPE)
- Assessing compromised third-party Actions, mutable version tags, and Actions cache poisoning
- Dependency confusion, typo/slopsquatting, and malicious package/install-hook payloads
- Self-hosted / non-ephemeral runner abuse and runner backdoors
- CI secret exfiltration and OIDC cloud-role (AWS/GCP/Azure) trust-policy abuse
- Validating SLSA build provenance and signing gates (defense / blue-team validation)
## Technique Map
| Technique | ATT&CK | CWE | Reference | Script |
|-----------|--------|-----|-----------|--------|
| Pwn request (`pull_request_target` checkout of fork head) | T1195.001 | CWE-269 | references/pipeline-poisoning.md | scripts/workflow_auditor.py |
| Script injection (`${{ github.event.* }}` into `run:`) | T1059 | CWE-94 | references/pipeline-poisoning.md | scripts/workflow_auditor.py |

How to install
mdr add hypnguyen1209/offensive-claude/cicd-supply-chain@sha256:0b371f773891985cThe line at the top of this page pins the label git:20260629.9f4a1a5, 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.
