What happened

This Microsoft Security Blog collection (July 2026) highlights multiple high-risk trends: active credential- and token-stealing campaigns (ACR Stealer using ClickFix lures), npm supply-chain compromise of AsyncAPI via CI/CD and import-time payload delivery, OAuth abuse and vishing linked to ShinyHunters, and a destructive backdoor (GigaWiper/BLUERABBIT) combining multiple wiping/ransomware capabilities. It also covers defensive guidance: least-privilege and identity/tool binding for autonomous AI agents, Entra ID updates (passkeys as default and new SMS/voice model), Microsoft Defender Experts
