Somewhere between 51,000 and 200,000 records were stolen from Montgomery Ward’s servers last December—the company says it’s the smaller number, but CardCops, the group that spotted the hack in the first place, “spotted hackers touting the sale of 200,000 payment cards belonging to one merchant” in June, which is how the story became public.

But although it’s the biggest example so far of retail data theft, TJ Maxx isn’t the only retailer doing a poor job of keeping sensitive data protected from hackers.
