Office goods retailer Staples recently saw themselves fall prey to hackers, much as Target, The Home Depot, and a laundry list of retailers ahead of them have. The company has now addressed the hack, saying that over one million unique cards were compromised. The hack also affected more than 100 point-of-sale systems at 1,400 stores. Staples didn’t say if the breach was nationwide, or if a specific geography was affected. The window for this hack was short, though, only lasting about a month.
