They found it significantly outperforms previous models at analyzing source code (program code written by developers) to identify vulnerability candidates, especially in complex areas like native application analysis (testing software written in languages like C or C++), though it works better as a tool to assist human experts rather than as a replacement for hands-on security testing.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://www.bleepingcomputer.com/news/security/xbow-tests-anthropics-mythos-preview-for-offensive-security/","publishedAt":"2026-06-09T16:16:38.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Mythos Preview","Claude Code","Claude","GPT 5.5","Opus 4.7"],"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":"2026-06-09T16:16:38.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
