{"data":{"id":"253fcf6c-42b3-4ddb-b5fc-8386325dbf17","title":"AI-powered defense for an AI-accelerated threat landscape","summary":"AI models can now autonomously discover vulnerabilities and create working exploits, which compresses the time between when a weakness is found and when it's attacked. However, the same AI capabilities that help attackers can also help defenders by accelerating vulnerability discovery and reducing response time. Microsoft is partnering with AI model providers and using tools like advanced models to identify security issues faster and deploy fixes through their existing update processes.","solution":"Microsoft states it will incorporate advanced AI models directly into its Security Development Lifecycle (SDL) to identify vulnerabilities and develop mitigations and updates. Mitigations are handled through the Microsoft Security Response Center (MSRC) processes, including Update Tuesday (the regular monthly security update distribution) and out-of-band updates when needed. For customers using Microsoft PaaS and SaaS cloud services, mitigations and updates are applied automatically. For customers deploying on their own infrastructure, staying current on all security updates is described as a fundamental requirement. Microsoft will also deploy detections to Microsoft Defender when updates are released and share details through the Microsoft Active Protections Program (MAPP) to help partners mitigate risk.","labels":["security","policy"],"sourceUrl":"https://www.microsoft.com/en-us/security/blog/2026/04/22/ai-powered-defense-for-an-ai-accelerated-threat-landscape/","publishedAt":"2026-04-22T17:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Microsoft","Anthropic"],"affectedVendorsRaw":["Microsoft","Anthropic","Claude Mythos Preview"],"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":"2026-04-22T17:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","availability"],"aiComponentTargeted":null,"llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
