( CNN ) -- Sony said the Internet security breach targeting its networks was more extensive than originally thought . Hackers also gained access to databases containing subscriber information for Sony Online Entertainment , a San Diego subsidiary that makes online multiplayer games for computers and the PlayStation 3 . The Sony division took its Web services offline Monday . That shutdown came 12 days after Sony Computer Entertainment disconnected the PlayStation console game network and Sony Network Entertainment shut down Qriocity media streaming services . Sony said last week that it expected to start restoring some services this week , but they remain offline . Sony disclosed the first breach on April 22 , and then on April 27 , the company announced that personal info and perhaps credit card numbers had been stolen for as many as 77 million accounts . With the PC game network also compromised , Sony adds 24.6 million accounts to the pot . Some popular games maintained by Sony 's online division include `` EverQuest , '' `` DC Universe Online '' and `` Free Realms . '' This additional network was targeted on April 16 and April 17 , the same days the other networks were hacked . While the infrastructures are separate , `` There 's a degree of architecture that overlaps '' among Sony 's many networks , said Michele Sturdivant , a spokeswoman for Sony Online Entertainment . `` Initially , we believed that data was not stolen , '' she said , but then the company uncovered evidence to the contrary during its ongoing investigation . `` They used very sophisticated means to access the data , and they used sophisticated means to cover their tracks . '' The information hackers took from Sony Online Entertainment 's system included users ' names , home addresses , e-mail addresses , phone numbers , login names , encrypted passwords , birth dates and genders . Unlike the last breach , hackers did n't get the answers to security questions or have access to most people 's financial information . However , information from an additional 12,700 users stored on a database that was retired in 2007 was also compromised , Sony said . The data there included credit and debit-card numbers and expiration dates , but not security codes , for non-United States residents , as well as direct-debit banking records for some customers in Austria , Germany , the Netherlands and Spain . Sony apologized for the security lapse and outages on Sunday . The company plans to offer PlayStation account holders a 30-day voucher for the PlayStation Plus service , which lets gamers download free and exclusive games . Current Plus subscribers will get an extra 30 days added to their accounts . Similarly , Sony Online Entertainment will add 30 days to customers ' accounts , along with additional play time for each day the service is down . The company also says it is in the process of outlining how it will recompense gamers who own its PlayStation 3 games . Additionally , Sony will offer complimentary assistance for customers who want to enroll in identity theft protection programs . Sony says it 's working with the Federal Bureau of Investigation to make sense of the security breach . On Monday , PlayStation spokesman Patrick Seybold denied a report that said the hacker group offered to sell Sony a list of credit card numbers stolen from its systems .
Sony said its online - game servers were also compromised in the incident . This adds 24.6 million accounts to the 30 million that were already compromised . Sony shut down the networks for ` ` EverQuest '' and ` ` DC Universe Online '' on Monday .
