Credit card numbers stolen from buy.com customers

JoeyRox writes: There is no press about this yet but over 100 buy.com customers (now rakuten.com) have reported their credit card numbers stolen and used for unauthorized charges after placing orders on Rakuten's website. A thread about the breach can be read here (http://slickdeals.net/f/6018544-Rakuten-Buy-com-Fraudulent-Use-of-Credit-Card-Info-within-Company?). Rakuten representatives are participating on the thread and asking victims to contact them but have yet to provide any details about the nature of the breach.
