{"data":{"id":"1f1d28ea-3c08-4040-98eb-5556855f9ecd","title":"Pop Goes the Verifier: Phoneme-Targeted Data Poisoning of Voice Liveness Detection","summary":"The paper introduces Pop Goes the Verifier, a data poisoning attack against VoicePop, a liveness detection technique in Automated Speaker Verification Systems that classifies low-frequency pop bursts from plosive phonemes using GFCC features and an SVM. The attack uses FastSpeech 2 with a modified HiFi-GAN vocoder to inject localized pop bursts at plosive locations, plus subtle Gaussian noise to reduce visibility. On ASVSpoof 2019, it achieves a moderate poisoning effect and resists signal-level inspection better than the prior SyntheticPop attack, which reduced accuracy to 14.01% with 20% poisoned samples but produced easily detectable artifacts.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://arxiv.org/abs/2611.01095v1","publishedAt":"2026-10-31T16:35:38.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_poisoning"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["FastSpeech 2","HiFi-GAN","VoicePop","SyntheticPop"],"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":"2026-10-31T16:35:38.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity","availability"],"aiComponentTargeted":"training_data","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":"preprint","atlasIds":null}}
