Six Miami-area residents were arrested last week for using stolen credit card information that came from the TJX security breach which was disclosed to the public earlier this year. The Florida residents allegedly purchased about $8 million in gift cards and electronic goods using the fraudulent data. Police indicated the fraudulent data may have been obtained a month before the December discovery time frame previously disclosed by TJX. Meanwhile, a major shareholder of TJX has filed a lawsuit to obtain records showing how the retailer handled computer problems that exposed customer information to hackers. Arkansas Carpenters Pension Fund said TJX rebuffed its request to see if the board was doing its job properly.
