The TJX Data Breach - The Gift Just Keeps on Giving

The Boston Globe reported this morning that the data breach at TJX affected 94 million customers, more than twice the number TJX had admitted to previously. According to the article:

"The data breach affected about 65 million Visa account numbers and about 29 million MasterCard numbers ...A Visa official also put fraud losses to banks and other institutions that issued the cards at between $68 million and $83 million on Visa accounts alone."

TJX claims its costs of the breach will remain about $256 million - although, given past history, I wouldn't place any bets.

I wonder how long ago TJX knew these "new" numbers, but "forgot" to let its investors (or customers) know.

BTW, the original hacker(s) have still not been caught.
