It is expected that Sony's head of gaming division, Kaz Hirai, will speak to journalists in Tokyo about the hack that forced the company to pull down the PlayStation and Qriocity services. Sony said that Hirai will describe PlayStation Network's system security measures and service restoration plan.
Sony took the PlayStation Network, an online gaming service, offline on Apr 20 after hackers managed to intrude to the network and stole users' personal details including password and credit card details. Later, Sony confirmed the hacking attempt and informed PlayStation Network users about the data breach.
Meanwhile, a US congressional committee sent a letter addressed to Kaz Hirai, who is also the chairman of Sony's US gaming unit, for explaining the issues surrounding the leak of PlayStation Network user's personal information.
The letter sent by a subcommittee of the House of Representatives' Committee on Energy and Commerce asked Sony to answer many questions that Sony's users have about the hack and the company's response. The letter seeks answer for questions including whether the account data of all customers was stolen, how the breach happened, and whether the company identified culprits behind the attack.
"Sony's public statements suggest there is no evidence credit card data was taken, but such a scenario cannot be ruled out. Given the amount and nature of the personal information known to have been taken, the potential harm that could be caused if credit card information was also taken would be quite significant," the letter said.
