OSAKA -- Hackers possibly stole as many as around 350,000 files in a recent attack on gaming giant Capcom Co., including personal information, data on client companies and internal documents, the firm announced on Nov. 16.
Osaka Prefectural Police have begun questioning figures at the company about how the attack unfolded, and are investigating the case.
According to Capcom, the data that may have been leaked includes the names, addresses and contact details of individual customers; the names, addresses and stock holdings of shareholders; documents concerning the firm's own product development and sales; and human resources files on employees.
The cyberattack was launched by a hacker group calling itself Ragnar Locker, which demanded a ransom in virtual currency. Sources said that it had been confirmed that the group used a ransomware virus in the attack.
"We deeply apologize for the trouble we've caused to our customers and all other related parties. We will pour yet more effort into strengthening our management systems, and deal harshly with any criminal actions," Capcom said in a statement.
