Notable incidents include cybercriminals exploiting an AI tool agent to access cloud provider Vercel’s customer data via Google Workspace credentials. Techniques include “vibe coding” outside approved environments and sharing login credentials with AI tools (16% reported). No specific malware, CVEs, or infrastructure details were provided. **Recommended Response** Implement AI governance frameworks emphasizing identity-centric controls, automated discovery of AI tool usage, and secure sandbox environments for testing AI applications.
