Sony seems to have become a favorite target for hackers with an Internet service provider that it owns and operates, called So-Net, now targeted by unknown groups, with about 100,00 Yen in virtual currency stolen from some of its customers.

The value of the stole currency is low, about 1,224 in dollars, and just 128 customers were affected, but the new attack on Sony operated services shows that the company might have more problems up ahead and might persuade more possible customers to stay away from its services.

This attack has not managed to get any personal information, Sony says.

The company issued a statement to its customers, saying, “At this point in our investigations, we have not confirmed any data leakage. We have not found any sign of a possibility that a third party has obtained members' names, address, birth dates and phone numbers.”

It seems that other Sony operated sites were also hacked for a short period of time and redirected to a fake page that requested personal information from users.

Sony says that it currently does not know who has launched these attacks and that it is taking all measures to make sure that they do not happen again.

Both the PlayStation Network and related services are now back up online and padded with extra security measures.

PlayStation 3 users also have to download a new mandatory update, firmware 3.61, which adds to the protections of the console.

Sony took the PSN down on April 20 after hackers managed to penetrate its security and steal the personal information, including credit card information, from a huge number of customers.

Since then the password reset page for the PSN has also been targeted by hackers.

Sony has pointed the finger to Internet activist group Anonymous as the source of the attacks, but so far no conclusive evidence has been produced.
