On June 18, 2019, Chubu Electric Power, Keio University, and Hitachi announced that they have validated a method to detect the evidence of difficult-to-identify cyberattacks by analyzing Darknet communications.[1] These efforts will contribute to preventing the potential damage caused by cyberattacks.

While digitalization has enhanced convenience in everyday life, it also increases the risks of cyberattacks. It is urgent for society to address cyber security challenges and strengthen the resilience of critical infrastructure. Accordingly, Keio University, Chubu Electric Power, and Hitachi have been studying Darknet communications since April 2017. After analyzing a vast number of Darknet communications, approximately 20 million cases per day, the study confirmed that the sign of cyberattacks could be identified by tracking and using correlation analysis on the communications made by multiple organizations.
