Timeline of AI supply chain attacks from PyTorch dependency confusion to recent model zoo compromises

⚡ Key Takeaways

  • Pretrained models from public zoos like Hugging Face hide backdoors in parameters, evading standard code scans.
  • AI supply chains lack provenance, mirroring SolarWinds but with uninspectable weights.
  • Secure by auditing origins, sandboxing inference, and demanding signed model passports.
