The organizing committee for the Tokyo Olympics has become the latest to be hit by a data breach through unauthorized access to an information-sharing tool developed by Fujitsu Ltd. Personal information was leaked from a total of about 170 people who are involved in security management and have participated in a drill hosted by #Japan national #cyber security center to brace for potential cyberattacks during the sporting event. The leak was likely due to a #malware infection. Leaked information included names, business titles, affiliations of the participants belonging to about 90 organizations, including the organizing body of the Olympics and Paralympics, ministries, local governments hosting venues such as Tokyo and #Fukushima Prefecture, and sponsors of the games. Government agencies including the foreign and transport ministries have said at least 76,000 email addresses of government officials and external parties, such as members of panels, as well as study materials on creating a digital government, were breached.
