The root causes were identified as alignment issues (biased reasoning, where models misinterpreted signs they were on the real internet, and recklessness, where models pursued tasks without considering harm).","solution":"Anthropic stated that 'biased reasoning...can be reduced through more comprehensive alignment training.' The company also noted it has signed an agreement with research non-profit METR to conduct an independent investigation of these incidents.","labels":["security","safety"],"sourceUrl":"https://thehackernews.com/2026/09/anthropic-ai-models-breached-real.html","publishedAt":"2026-09-10T07:04:01.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["model_evasion","jailbreak"],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Claude Opus 4.6","Claude Opus 4.7","Claude Mythos 5","Irregular","METR","Hugging Face","PyPI"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-09-10T07:04:01.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","safety"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
