However, neither attack threatens real-world security because the Hawk attack only works on smaller key sizes that aren't being deployed, and the AES attack requires impractical conditions like access to billions of encrypted outputs.","solution":"N/A -- no mitigation discussed in source.","labels":["research","security"],"sourceUrl":"https://www.csoonline.com/article/4202920/mythos-takes-its-first-shot-at-post-quantum-cryptography.html","publishedAt":"2026-07-29T15:17:06.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Claude Mythos","NIST"],"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":"2026-07-29T15:17:06.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":null,"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
