{"data":{"id":"4f68c450-7de8-428c-b5c3-65afbdbc8c00","title":"MicroPatch: Directed Backdoor Erasing via Victim Parameter Decoupling","summary":"MicroPatch is a backdoor erasing approach for deep neural networks that targets the model parameters influenced by backdoor triggers. It reconstructs trigger patterns through reverse engineering, uses influence functions to separate victim parameter components from clean ones, and patches those components. The authors report that across four datasets and four representative backdoor attacks, plus spatial-frequency and frequency-domain attacks, MicroPatch reduces attack success rates more than existing methods while keeping high classification accuracy.","solution":"The source describes MicroPatch itself as the proposed mitigation: patching decoupled victim parameter components to purify the model. No separate fix, patched version or configuration change is stated.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11570851","publishedAt":"2026-06-18T13:16:36.000Z","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":"2026-06-18T13:16:36.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":"peer_reviewed","atlasIds":null}}
