Experian tracked 2,000 AI-driven data breaches among 5,000 total incidents in 2025, with the firm predicting autonomous AI agents will become the primary breach vector in 2026.
Data security firm Experian reported that artificial intelligence powered 40% of the 5,000 data breaches it serviced during 2025, marking a significant shift in how attackers compromise systems.
The company's findings suggest that AI-enabled attack methods have matured beyond experimental stages into mainstream breach tactics. Of the 5,000 incidents Experian managed, approximately 2,000 involved AI-powered components.
Experian's outlook for 2026 raises further concerns. The firm predicts that agentic AI—autonomous systems designed to operate independently with minimal human intervention—will become the leading cause of data breaches next year. Unlike current AI-powered attacks that typically require human direction, agentic AI systems could potentially identify vulnerabilities and execute attacks with greater speed and minimal oversight.
The shift reflects broader trends in cybersecurity where attackers adopt emerging technologies to enhance their capabilities. AI can accelerate common breach techniques including credential stuffing, phishing campaigns, and vulnerability scanning. Agentic AI could amplify these threats by automating decision-making processes in real time.
The data underscores growing urgency around AI security. Organizations have invested heavily in deploying AI systems across operations, but corresponding security measures have lagged. The gap between AI adoption and AI defense mechanisms creates exploitable openings for threat actors.
Experian's predictions suggest cybersecurity strategies will need to evolve rapidly to address autonomous attack systems. Current defenses often depend on detecting unusual patterns or human behavioral indicators—approaches that may prove insufficient against fully autonomous agents operating at machine speed.
