Supply Chain Security & Provenance

Threats mitigated

• T1 Memory Poisoning

  Attackers inject malicious data into the agent's memory to manipulate future decisions, affecting any memory type from in-agent session to cross-agent cross-user memory.

• T2 Tool Misuse

  Manipulation of tools, APIs, or environment access to perform unintended actions or access unauthorized resources, including exploitation of access to external systems.

• T3 Privilege Compromise

  Breaking information system boundaries through context collapse, causing unauthorized data access/leakage, or exploiting tool privileges to gain unauthorized access to systems.

• T11 Unexpected RCE and Code Attacks

  Tools or environments enabling unexpected code execution, presenting direct risks to code execution environments.

• T13 Rogue Agents in Multi-Agent Systems

  Compromised AI agent activity outside monitoring limits or orchestration in multi-agent systems.

• T17 Supply Chain Compromise

  Vulnerable, malicious or outdated components enter the agent through models, libraries, tools, plugins, prompt templates, build environments or framework updates.

OWASP AISVS coverage

  Verify that model weights, datasets, and fine-tuning adapters are downloaded only from approved sources.

• C6.1.3 Level 2

  Verify that every third-party model artifact can be integrity-verified.

• C6.1.4 Level 2

  Verify that models pass a behavioral acceptance test suite before being promoted to any non-development environment.

• C6.2.1 Level 1

  Verify that every model artifact publishes a version-controlled, machine-readable AI BOM listing datasets, weights, licenses, and data-origin statements.

• C6.2.2 Level 2

  Verify that AI BOMs are cryptographically signed before deployment.

• C6.2.3 Level 2

  Verify that AI BOM completeness checks fail the build if any component metadata is missing.
