This approach helps protect against model theft and unauthorized copying by giving developers a way to prove ownership if their model appears elsewhere.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://dlnext.acm.org/doi/abs/10.1145/3817059?ai=2p1&mi=hx017f&af=R","publishedAt":"2026-07-24T18:01:16.433Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_theft"],"issueType":"research","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":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":"peer_reviewed","atlasIds":null}}
