A ransomware attack at food and beverage giant Asahi Group Holdings last September led to the leak of 115,513 sets of personal data, the company has said.
Of the total, 110,396 sets included the names and phone numbers of client companies¡¯ executives and employees, and 5,117 included the names and addresses of Asahi Group workers, including some no longer with the firm, according to the group¡¯s announcement Wednesday.
Asahi Group said in November that 18 sets of information were confirmed to have leaked while 1,914,000 may have leaked.
On Wednesday, the company also unveiled detailed measures to prevent recurrence, such as strengthening functions to detect and block suspicious activity in computers and network facilities, setting up an internal organization for information security and appointing an executive with responsibility for its work, and enhancing employee education.
The cyberattack caused a system glitch that forced Asahi Group to suspend production and shipments at most of its domestic plants and process orders manually.
Production and shipments gradually resumed from December, and the company¡¯s logistics system was restored this month.
