Since launching last month, the program has identified over 10,000 high-severity vulnerabilities across critical software, with 97 already patched and 88 security advisories issued. However, Anthropic notes that finding vulnerabilities is much easier than fixing them, presenting a major challenge for cybersecurity.","solution":"Anthropic recommends that software developers and network defenders shorten their patch cycles and deployment timelines. Specific steps mentioned include: hardening networks' default configurations, enforcing multi-factor authentication (requiring two or more ways to verify identity), and keeping comprehensive logs for detection and response. Additionally, Anthropic launched a Cyber Verification Program that allows security professionals to use its models without safety restrictions for legitimate purposes such as vulnerability research, penetration testing, and red teaming (simulated attacks by friendly security experts).","labels":["security","industry"],"sourceUrl":"https://thehackernews.com/2026/05/claude-mythos-ai-finds-10000-high.html","publishedAt":"2026-05-23T11:55:35.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Claude Mythos","OpenAI","GPT-5.5-Cyber","WolfSSL","Oracle","Microsoft","XBOW"],"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":"2026-05-23T11:55:35.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","availability"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
