The NSA and GCHQ reportedly stole encryption keys used in SIM cards manufactured by Gemalto. The Netherlands-based company supplies SIM chips used widely in mobile products from AT&T, Verizon, T-Mobile, Sprint and more than 400 wireless service providers around the world. The stolen keys give the two agencies a way to intercept and monitor cellphones without the need for a warrant or a wiretap. The agencies saw the keys as providing them with an easy way around local and international laws governing surveillance of cell phone communications.”]
