{"data":{"id":"a9f2853c-5261-4cbb-add3-10d212ae6771","title":"DiffHash: Text-Guided Targeted Attack via Diffusion Models Against Deep Hashing Image Retrieval","summary":"DiffHash is a diffusion-based targeted attack against deep hashing models used for large-scale image retrieval. It optimizes the latent representations of images, guided by text generated by a Large Language Model for the target image, and uses a multi-space hash alignment network to map image and text spaces into the binary hash space. The authors report that it outperforms state-of-the-art targeted attacks, with better black-box transferability and more stable results across datasets.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11523539","publishedAt":"2026-05-18T13:18:18.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_evasion"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Large Language Model (LLM) used for text guidance","deep hashing image retrieval models"],"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":"2026-05-18T13:18:18.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":"peer_reviewed","atlasIds":null}}
