The Changing Landscape of Cyber Risk: An Empirical Analysis of Loss Severity and Tail Dynamics

This paper analyzes cyber risk severity and tail risk using three databases. Malicious cyber incidents show increased severity since 2018, while negligent incidents decline. Cyber loss distributions are extremely heavy-tailed. Findings highlight the need for dynamic, category-specific risk management and insurance pricing.

The Changing Landscape of Cyber Risk: An Empirical Analysis of Frequency, Severity, and Tail Dynamics

Cyber risk presents significant challenges to society, yet its statistical behavior remains insufficiently understood. This paper analyzes three databases to study cyber risk dynamics. It identifies increasing frequency and severity, particularly in malicious events since 2018. Persistent heavy-tailedness across risk categories implies lower insurance demand and potentially heightened risk levels for firms.
