Verizon DBIR spotlights the rise of “shadow AI” in workplace data leakage
Verizon's 2026 Data Breach Investigations Report identifies unauthorized employee use of generative AI tools—termed "shadow AI"—as a significant insider-risk and data-loss threat. The report documents a sharp increase in workers uploading corporate information into public AI services, frequently through personal accounts accessed on company devices. Employee use of unapproved AI tools has tripled to 45 percent, while regular AI adoption on corporate devices jumped from 15 to 45 percent year-over-year, with two-thirds of users accessing AI services through non-corporate accounts.
