TJX Breach Was Twice as Bad as First Reported
The largest digital data theft ever recorded was bigger than originally thought. TJX, the Massachusetts retail giant that earlier this year disclosed that a series of network and computer intrusions had compromised more than 45 million credit- and debit-card numbers, may have lost more than twice that number, according to reports.
A group of banks suing TJX over the compromises now claim that more than 94 million accounts were affected in the break-ins, according to The Boston Globe. The thefts included about 65 million Visa account numbers and roughly 29 million MasterCard credentials.
TJX believes intruders stole the data via insecure wireless networks at two Marshalls stores in Miami. That's a pretty expensive security "oops." From the Globe story:
"Several analysts have estimated that the total costs to TJX could ultimately run as high as $1 billion, including legal settlements and lost sales." To date, though, it doesn't appear as though consumers are holding it against the company. The Globe notes that sales figures reported by TJX suggest that shoppers at TJX stores such as TJ Maxx and Marshalls have not been put off by the breach.
