What happened
A collection of Microsoft Security Blog posts (Apr 2026) describing an AI-accelerated threat landscape and the defensive measures Microsoft and partners are deploying. Key themes include Microsoft’s partnership with Anthropic to operationalize large models for defensive use, adapting incident response and SecOps for AI-driven attacks, and evolving detection across cloud identities and remote access. Several posts detail active threats and attack patterns: cross-tenant Teams helpdesk impersonation used to gain remote access and exfiltrate data, a domain compromise stopped by predictive/exposure
