{"data":{"id":"6bc65002-2f19-4eaf-82dd-407128c0c932","title":"Action-Level Backdoor Attacks Against Deep Reinforcement Learning Systems via Adaptive Reward Exploration","summary":"Adapdoor is an attack framework that injects action-level backdoors into deep reinforcement learning models during training, so that adversaries can manipulate action outputs at deployment. It initializes the backdoor reward from benign reward statistics and iteratively fine-tunes it using performance feedback from benign and backdoor tasks. Across 3 DRL algorithms, 11 environments and 53 backdoor tasks, it outperforms existing baselines by 42.0% to 144.2%.","solution":"The source says the authors evaluate three potential defenses to explore pathways for mitigating this threat, but it does not name them or state a fix.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11675897","publishedAt":"2026-09-02T13:16:59.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_poisoning"],"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":"2026-09-02T13:16:59.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity","safety"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":"peer_reviewed","atlasIds":null}}
