LONDON – Sony Pictures is investigating hackers’ claims that they have stolen more than 1 million pieces of user information in another attack on the entertainment company’s networks.

A group of hackers calling itself LulzSec said in a written statement that it has obtained users’ personal information, including passwords, email addresses, home addresses, dates of birth, and all Sony opt-in data associated with their accounts.

Sony Pictures, a unit of Sony Corp. of America, said Thursday that it is aware of LulzSec’s claim and looking into it.

If confirmed, the breach would deal yet another blow to Sony, which suffered a massive cyberattack in April that targeted credit card information through its PlayStation Network and Sony Online Entertainment networks. Over 100 million user accounts were affected and the company only recently was able to restore service.

LulzSec said Thursday that none of the data it accessed from Sony was encrypted, “which means it’s just a matter of taking it.”

“They were asking for it,” the group said in its statement.
