It purifies the encoder through self-supervised distillation without label information, adding adversarial contrastive learning to strengthen the teacher model. Across four node and four graph classification datasets, GDetox reduced the attack success rate to 4% with encoder performance degrading by no more than 2%.","solution":"GDetox: a backdoor defense that purifies a backdoored graph encoder via self-supervised distillation, using adversarial contrastive learning to strengthen the teacher model.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11456780","publishedAt":"2026-03-26T13:17:10.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["other"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"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":"2026-03-26T13:17:10.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":"peer_reviewed","atlasIds":null}}
