NEW YORK (

TheStreet

Sony

(SNE) - Get Report

said Tuesday it doesn't know when it will be able to fully restore service to its PlayStation Network, which was shut down last month following a massive security breach that affected more than 100 million online accounts.

"I know you all want to know exactly when the services will be restored," Sony spokesman Patrick Seybold said in a

statement on the company's PlayStation blog

on Tuesday. "At this time, I can't give you an exact date, as it will likely be at least a few more days."

Sony recently confirmed that hackers were able to access

personal data from 24.6 million user accounts at its Sony Online Entertainment division

, which makes multiplayer online games, in the attack.

Sony also warned another 77 million PlayStation users around the world that their private account details, such as passwords, names, birth dates, addresses and credit card data, may have been compromised when its network was

infiltrated by an unknown hacker

, Sony Computer Entertainment spokesman Satoshi Fukuoka said.

While Sony has not received any reports of illegal uses of compromised information, the company is

continuing to investigate the hack

.

"We're terribly sorry for the inconvenience," Seybold said in Tuesday's post "and appreciate your patience as we work through this process."

Sony shut down the PlayStation network, the system that provides online gameplay and digital shopping for owners of PlayStation 3 and PSP devices, on April 20 after what Sony called an "illegal intrusion" on its servers.

The network was down for nearly a week before Sony notified its users about the PlayStation Network security breach. The company notified consumers of the breach on April 26 even though it began investigating unusual activity on the network since April 19.

Last month, U.S. lawyers filed a lawsuit against Sony on behalf of lead plaintiff Kristopher Johns for negligent protection of personal data and failure to inform players in a timely fashion that their credit card information may have been stolen. The lawsuit seeks class-action status.
