The model can identify bugs that were previously hard to detect, including a 27-year-old bug in OpenBSD (an operating system focused on security), and Anthropic is working with U.S. government agencies to manage the risks of this powerful cybersecurity capability.","solution":"Anthropic is limiting access to Claude Mythos Preview by only providing it to a select group of companies, including Apple, Google, Microsoft, Nvidia, and Amazon Web Services, along with over 40 other firms, for defensive security work. Additionally, the company stated it 'has been in ongoing discussions' with U.S. government officials including the Cybersecurity and Infrastructure Security Agency and the Center for AI Standards and Innovation about the model's cyber capabilities.","labels":["safety","security"],"sourceUrl":"https://www.cnbc.com/2026/04/07/anthropic-claude-mythos-ai-hackers-cyberattacks.html","publishedAt":"2026-04-07T19:52:22.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Anthropic","Claude Mythos Preview","Apple","Google","Microsoft","Nvidia","Amazon Web Services","CrowdStrike","Palo Alto Networks","OpenAI","OpenBSD"],"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":"2026-04-07T19:52:22.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","safety"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
