What happened
Microsoft Security Blog posts (Apr 2026) cover AI-powered defenses and industry collaboration (including Anthropic) to scale detection and response, plus guidance on adapting SOCs and incident response for AI-driven threats. Operational threat coverage includes cross-tenant Microsoft Teams helpdesk impersonation leading to lateral movement and data exfiltration, domain compromise containment using predictive shielding, and detection strategies for infiltrating IT workers across cloud and identity telemetry. Technical posture guidance addresses cryptographic inventory and quantum‑safe readiness
