The Japanese electronics firm, which is pouring resources into expanding its online services, was the target of several large-scale attacks last year.

In October, the company suspended 93,000 user accounts on several of its gaming and entertainment networks after a large number of unauthorized login attempts on those accounts.

In April, Sony was the victim of a massive attack on its online properties, in which 100 million accounts were stole from company databases. The company shut down several networks for a month and a half.
