What happened
Microsoft Security Blog’s July 2026 feed covers AI security and governance, global AI red teaming, evolving phishing and Teams-based social engineering, ACR Stealer ClickFix intrusion chains, least-privilege controls for AI agents, incident response, and an AsyncAPI npm supply-chain compromise involving import-time malware delivery. The most actionable threats are credential and token theft by ACR Stealer and malicious package-based compromise of CI/CD and developer environments.
