Resilience Claims Data Shows Human Error Drove Majority of Cyber Losses in First Half of 2026
New data from Resilience, a cyber risk solutions company, reveals that over 85% of incurred cyber losses during the first half of 2026 were driven by attacks exploiting human error. Tactics such as phishing, social engineering, and transfer fraud accounted for most incidents, despite AI being expected to introduce more sophisticated threats. Interestingly, no financial loss was attributed directly to AI-specific attack vectors like prompt injection or model exploitation during the same period. However, AI is enhancing traditional methods by making them more effective. Ransomware remained a major cause of losses, responsible for 73% of incurred costs despite representing only 5.8% of total claims. Resilience highlights that while ransomware attacks are relatively rare, they remain highly costly due to business interruption and payouts. The company also notes an increase in the adoption of immutable backups, which may be contributing to fewer ransomware-related claims.
