"Following up on this morning's news that Sony Online Entertainment servers were offline across the board, Japanese newspaper Nikkei reports (via BGR) that the company has lost 12,700 customer credit card numbers as the result of an attack. The company apparently took SOE servers offline after learning of the attack last evening, but has yet to issue a statement confirming that customer information has been lost.
Of the 12,700 total, 4,300 are alleged to be from Japan, while the remainder's origins are unknown. The report also notes that most of the numbers are said to be from expired cards, which Engadget posits could mean this was simply stolen data from an old backup.
The report doesn't mention whether last night's supposed breach is connected to the recent incidents involving Sony's PlayStation Network and Qriocity services, though an SOE representative told Joystiq that official comment would be coming from the company "within the hour.""
