ReversingLabs countered that five versions of the same PowerShell stager, each with a different hash, kept identical behavior over 25 days, which left them open to detection. Analysts say AI makes rebuilding faster but does not change the malware's core malicious behavior.","solution":"N/A -- no mitigation discussed in source.","labels":["security","industry"],"sourceUrl":"https://www.csoonline.com/article/4235447/malware-evasion-made-easier-with-ai-but-behavior-still-gives-it-away.html","publishedAt":"2026-10-16T08:25:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"low","attackType":["other"],"issueType":"news","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Claude"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-10-16T08:25:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
