Experian: 40% of 2025 Breaches AI-Powered; Agentic AI Is #1 2026 Threat

Experian, which managed 5,000 data breach incidents in 2025, reports that 40% were AI-powered attacks. In its 2026 forecast, Experian predicts that agentic AI will become the leading cause of data breaches — the first time a major enterprise security firm has made a categorical public prediction singling out autonomous AI agents as the dominant threat vector. This prediction arrives in the same news cycle as the CamoLeak CVSS 9.6 vulnerability and a study finding 40% of vibe-coded apps leaking auth tokens.

Why It Matters

When the leading breach-management firm publicly designates a threat class as #1 before the year is half over, it signals that security operations centres are already seeing agentic AI attacks in volume — not just forecasting them theoretically. Enterprise AI deployments without agent-specific monitoring are operating blind.
