Sony is yet to determine if the personal information of PlayStation Network users has been compromised by the attack that has left PSN out of action for five days.
According to SCE Japan spokesperson Satoshi Fukuoka, that includes the security of user credit card details - although the firm has reassured PSN account holders that it will "promptly inform" them at the first sign of any foul play with their payment details. SCE is conducting a "thorough investigation" into the outage, he added.
Meanwhile, SCEA communications chief Patrick Seybold has released a company update on the continuing PSN downtime. He said earlier today:
"I know you are waiting for additional information on when PlayStation Network and Qriocity services will be online. Unfortunately, I don't have an update or timeframe to share at this point in time.
"As we previously noted, this is a time intensive process and we're working to get them back online quickly. We'll keep you updated with information as it becomes available. We once again thank you for your patience."
The PSN outage began in the early hours of Thursday in the UK - as Valve's Portal 2 arrived in stores. Sony has since clarified that an "external intrusion", or hack, is to blame for the downtime.
