The malware uses a chain of loaders to hide itself in system memory and communicates with attackers' servers, while impersonating updates from various security companies to spread further.","solution":"Users should ensure they download Claude from the official portal and skip or hide sponsored search results. The presence of 'NOVupdate' files on a system is a strong indication of compromise.","labels":["security"],"sourceUrl":"https://www.bleepingcomputer.com/news/security/fake-claude-ai-website-delivers-new-beagle-windows-malware/","publishedAt":"2026-05-07T10:02:35.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain"],"issueType":"news","affectedPackages":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Claude","Anthropic","PlugX","DonutLoader","G Data","CrowdStrike","SentinelOne","Trellix"],"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":"2026-05-07T10:02:35.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
