Hundreds of US businesses have unknowingly suffered a cyberattack

Is your payment information safe? It’s hard to know, considering many companies hit by the same cyberattack that hit Target don’t even know it. According to a New York Times report published Friday, more than 1,000 businesses, including Supervalu and United Postal Service (UPS), were caught up in a breach affecting in-store cash register systems. The Department of Homeland Security issued an advisory that said millions of American payment cards have been affected by the hack.
