Sony was again pummeled with a cyber attack when hackers broke into a Japanese subsidiary, So-net Entertainment, to compromise e-mail accounts and steal customer rewards points.

So-net Entertainment said that a computer from one IP address tried 10,000 times to get into the customer rewards service. Altogether, the hackers accessed more than 200 accounts and stole about $1,200 worth of points in an effort to redeem them. In addition, hackers also compromised around 90 customer e-mail accounts on the So-net network.

However, So-Net Entertainments said that it didn’t appear that customer addresses, and phone numbers had been exposed during the attack.
