Sony has confirmed that credit card payment processing details have not been compromised after a recent online security breach. A total of 93,000 accounts on its PlayStation Network, Sony Entertainment Network and Sony Online Entertainment services have now been suspended, after a three-day attack succeeded in matching valid login IDs and passwords. The accounts have temporarily been blocked and an investigation is underway to find the cause of the breach and to understand its full extent. Sony spokesman Sean Yoneda told the Associated Press that this recent cyber attack was not to the same extent of the breach in April which affected more than 100 million accounts. Mr Yoneda said: "This time nothing was taken or potentially taken from our data servers." Analysts have warned that this latest attack could threaten to further damage Sony's brand image and reputation, which signals the need for internet merchant account holders to maintain high levels of cyber security protection.
