{"data":{"id":"78bcdd87-0e02-49f1-9693-dc33d40cdb7e","title":"SVAttack: Spatial-Viewpoint Transfer Attack on Graph Convolutional Skeleton Action Recognition","summary":"Researchers investigate why adversarial attacks on graph convolutional skeleton action recognition models transfer poorly across architectures. They propose SVAttack, which combines a spatial gradient damper that suppresses model-specific spatial biases with a viewpoint-based constraint that improves imperceptibility. Across 3 benchmark datasets, 9 models, 7 attack methods and 2 defense methods, the approach significantly improves transferability while keeping skeleton motions visually plausible.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11695269","publishedAt":"2026-09-17T13:32:35.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_evasion"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-09-17T13:32:35.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity","safety"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.93,"researchCategory":"peer_reviewed","atlasIds":null}}
