What happened
This collection of Microsoft Threat Intelligence posts (June 2026) describes multiple high-impact threats and defensive guidance across developer and AI supply chains. Notable findings: a prompt-injection pathway in the Claude Code GitHub Action that could expose workflow secrets (research, responsible disclosure, and Anthropic mitigations); an updated taxonomy of failure modes for agentic AI based on a year of red teaming with seven new failure modes and practical mitigations; a large-scale npm supply chain compromise (“Miasma”) that infected >90 @redhat-cloud-services versions to steal CI/CD
