Threat actors behind the Emotet malware used the novel coronavirus (2019-nCoV) scare as a hook for their spam email campaign against targets in Japan.
2019-nCoV, which is believed to have originated in Wuhan, China, in the past month, has caused hundreds of deaths and thousands of confirmed cases in China alone. The virus has already spread to neighboring countries and confirmed cases have been reported in farther places such as Germany, Canada, and the U.S., causing the World Health Organization to declare a global health emergency. The official advisory of the Japanese Ministry of Health, Labour and Welfare on the outbreak can be found here (in Japanese).
