What happened
Microsoft Security Blog summaries (May–Jun 2026) highlight escalating threats across AI agents, software supply chains, developer environments, and enterprise networks. Key findings: an updated taxonomy of failure modes for agentic AI from a year of red teaming; a large-scale npm supply-chain credential‑stealing campaign (Red Hat “Miasma”) that preloads, persists, exfiltrates cloud/GitHub/CI credentials and self-republishes like a worm; dependency‑confusion and typosquatting campaigns profiling developers and stealing CI/CD/cloud secrets (including the Mini Shai‑Hulud activity); a self‑propag\
