Japanese electronics giant Sony has apologized to millions of online gamers and outlined proposals to overhaul its security systems after its network was breached by hackers.
Sony also revealed that ten million users had used their credit cards on the PlayStation Network online gaming platform to purchase games and other downloadable content such as music and films, reported Financial Times on its website.
In the meantime, the Japanese corporation reassured its mainly US members that chances were slim that card data had been accessed.
Kazuo Hirai, head of the Japanese group's networked products division, which includes the PlayStation franchise, said he was “deeply sorry for the great anxiety and trouble” inflicted on the network's 77 million users, whose names, e-mail addresses, passwords and other personal information were exposed to an unknown hacker.
The apology follows demands on Friday from members of US Congress that Sony explain when it knew of the breach, which forced it to shut down large parts of the US-based online gaming network, and why they took several days to notify customers.
Sony said it remained unclear exactly how much if any data had been copied by the hacker before the shutdown, but repeated that there was no evidence that customers' credit card information had been obtained.
The company unveiled a series of measures to reduce the risk of further security breaches of the network, promising to restore many of the functions on the online gaming very soon.
