Cyber insurer Resilience reported that attacks exploiting human error caused 85.3% of losses in its claims portfolio in the first half of 2026, up sharply from two years earlier, and attributed the shift to AI making phishing and payment fraud more convincing. Payment transfer fraud's share of insured losses roughly tripled, with fewer but larger successful attacks. The figures cover only Resilience's own claims data from January 2024 to June 2026.

• 85.3% of losses from human error
• up from 17.7% two years earlier
• transfer fraud 2.9% to 9.2% of losses
