A Brief Survey on Ransomware with the Perspective of Internet Security Threat Reports

摘要

The cyber security has become a mandatory aspect in every industry. The cyber security companies publish threat reports on regular basis. However, their reports are based on internal data and cannot provide complete network attack trends. In this study, we present a survey on malware and ransomware attack trends by using the data obtained from multiple threat reports. We collect, process, and analyze the data to present it in the form of information. The presented information is useful for corporate executives and cyber insurance companies to examine the impact of malware and ransomware attacks in the recent years. As future prospect, we would like to use the presented information to formulate a cyber risk model of ransomware attack. We would like to develop a model to estimate the potential losses of an organization due to a successful ransomware attack.
