Cyber insurer Resilience reported that attacks relying on tricking employees accounted for 85.3% of losses in its claims portfolio in the first half of 2026, up sharply from two years earlier. The firm attributes the rise to AI-generated phishing emails and cloned voices that make impersonation harder to spot. One case involved a finance chief authorising a wire transfer after a video call with synthetic copies of colleagues. The figures cover one insurer's own portfolio, not the wider market.
