What happened
This Microsoft Security Blog feed (May 7–14, 2026) covers multiple high-priority security topics: evolving defense-in-depth for autonomous AI agents and several AI-related attack surfaces (prompt injection→RCE in agent frameworks, exploitable Kubernetes/cloud-native AI app misconfigurations that can lead to RCE and data leakage). It details Kazuar, a modular P2P nation-state botnet attributed to the Russian actor Secret Blizzard, and an operational Linux local privilege escalation dubbed “Dirty Frag” that affects kernel networking/memory-fragment handling (Microsoft Defender reports active, in
