Forbes has a fairly complete writeup — woe if you shopped in Marshall’s, T.J. Maxx or any other TJX store from 03-04 — they’ve finally revealed the extent of the damage done, that we first heard about in January. Snip from TJX Says Info From 45.7M Cards Stolen:
Information from at least 45.7 million credit and debit cards was stolen by hackers who accessed TJX’s customer information in a security breach that the discount retailer disclosed more than two months ago.
TJX Cos. (nyse: TJX – news – people ), the owner of about 2,500 stores, said in a regulatory filing late Wednesday that about three-quarters of those cards had either expired at the time of the theft, or data from their magnetic strips had been masked – stored as asterisks rather than numbers.
But TJX acknowledged it still knows little about the full scope of the breach, in part because the hacker or hackers accessed TJX’s encryption software and could have known how to unscramble the information.
