AI Supply Chain Risk

What is AI Supply Chain Risk?

AI Supply Chain RiskThe set of threats arising from the third-party datasets, base models, libraries, plug-ins, and infrastructure that organisations combine to build and deploy AI systems.


Modern AI is rarely built from scratch. Teams pull base models from Hugging Face, fetch datasets from public crawls, install Python and Node packages, integrate with vector databases, and consume hosted-model APIs. Each link is a supply-chain risk: poisoned or backdoored model weights, malicious pickle files, typosquatted PyPI packages, prompt-injection payloads embedded in datasets, dependency confusion, compromised plug-ins, and unsafe inference infrastructure. The OWASP LLM Top 10 explicitly calls out supply-chain vulnerabilities, while NIST AI 100-2 and the EU AI Act push for traceability. Controls include AIBOMs, signed model artefacts (Sigstore for models, Model Signing Spec), provenance tracking, sandboxed loading of weights, dependency-pinning, and continuous monitoring of upstream registries.

Examples

  1. 01

    A Hugging Face model uploaded with a malicious pickle payload that executes code when loaded.

  2. 02

    A vector database client library typosquatted on PyPI that exfiltrates API keys during install.
