Evaluation containment

Isolation, egress control and monitoring around high-capability model evaluations.

Topic kind
pattern

Definition & limits

Cyber evaluations can become real attack surfaces when the model can reach shared infrastructure, production credentials or the open internet. The relevant boundary includes proxies, package caches, third-party ranges and monitoring, not only the nominal sandbox.

Examples

  • OpenAI's Artifactory path in the Hugging Face incident.
  • Anthropic third-party evaluation environments with unintended internet access.

Why this archive exists

The source matters after the headline fades.

DiggingBeagle is a non profit research project documenting AI security incidents, agent failures, vulnerabilities and AI-assisted operations. A case keeps its claims beside the sources that support, contest or limit them. Later updates stay visible, so a reader can see when the account changed.

We publish case reconstructions, dated reporting and analysis across records. Each has a different evidentiary role. About the project and our methodology explain how the work is reviewed.
