As millions of Playstation customers can attest, Sony's had a tough couple of months. In mid-April, the entertainment giant faced a PR nightmare as its online game network was intruded and users' personal and financial information stolen. The nightmare apparently is not yet over as it was reported Saturday that So-net Entertainment--a subsidiary of the Sony's--was intruded resulting in a the loss of $1,225 worth of online credits as reported by The Wall Street Journal. 

This is one of many bumps Sony has faced on its return back from disaster. A few days after the Playstation Network was relaunched in early May, another security exploit was exposed, which allowed hackers to change the users' login and passwords with the email addresses and user's date of birth previously stolen. 

To their credit, Sony Corp. has said that it intends to offer customers a Welcome Back Package, which includes subscription days for online playing as well as identity theft protection.  

In the matter of So-net, the company stated that there was no evidence of personal information being stolen. 

The Wall Street Journal reports:

"Although we can't completely rule out the possibility that there is a connection with the PSN issue, the likelihood is low," said Keisuke Watabe, a spokesman at So-net Entertainment. He said it was unlikely because the method of intrusion used was so different.

In a warning to users issued on Thursday, So-net said an intruder tried 10,000 times to access the provider's "So-net" point service, which grants customers reward points that can be exchanged for Sony products and online currency, from the same IP address. So-net said it thinks the intruder had usernames of account holders and then may have used an automated software program to generate passwords until it found the correct one.
