Sept. 6 (Bloomberg) -- Sony Corp. is investigating a hacker attack that exposed information on about 400 customers of the company’s mobile-phone business in China and Taiwan.
About 400 user names, matched with e-mail addresses, were disclosed online by a hacker group, George Boyd, a Tokyo-based spokesman for Sony, said today, declining to elaborate further. The Japanese electronics maker believes the data was obtained from a third-party service provider, Boyd said. No credit-card or bank-account data was compromised, he said.
The attack comes more than a year after Sony’s PlayStation Network services suffered a bigger data breach at a data center in San Diego. That incident compromised more than 100 million customer accounts and prompted Tokyo-based Sony to suspend online entertainment services for more than two months.
Shares of Sony, Japan’s biggest exporter of consumer electronics, fell 0.7 percent to 857 yen as of 1:12 p.m. in Tokyo, extending their loss this year to 38 percent.
A group believed to have links with the hacker collective known as Anonymous issued a statement saying it stole customer information from Sony’s mobile-phone unit, the Nikkei newspaper said earlier today.
Apple Inc. and the U.S. Federal Bureau of Investigation yesterday denied claims by hackers who said they stole information about 12 million Apple user accounts from an FBI computer. Cupertino, California-based Apple also said it didn’t provide any user information to the FBI or other organizations.
