Researchers introduced Behavioral Integrity Verification (BIV), a tool that compares what a skill says it does (in its documentation and metadata) against what its code actually does, and found that most skills deviate from their claims, with some containing dangerous multi-stage attack chains (sequences of seemingly harmless capabilities combined to steal credentials, execute unauthorized commands, or secretly extract data).","solution":"Security teams running LLM agents in production should inventory the third-party skills installed and require a behavioral-integrity check before installation rather than after. Palo Alto Networks customers can use Prisma AIRS and the Unit 42 AI Security Assessment service for protection.","labels":["security","research"],"sourceUrl":"https://unit42.paloaltonetworks.com/ai-agent-supply-chain-risks/","publishedAt":"2026-06-11T10:00:24.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["supply_chain","model_poisoning"],"issueType":"news","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-06-11T10:00:24.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality","availability"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
