More than a year ago, a certain flaw was discovered in the global mobile exchange system, and as reported by CBS’ 60 Minutes, it appears that this vulnerability is still being taken advantage of by hackers in order to gain unauthorized access to wireless data. The flaw specifically exists in Signaling System Seven (SS7), a full set of telephony signaling protocols that channels data between different mobile networks. In order to exploit this flaw, hackers need only get a certain phone number, and they could gain access to phone calls, text messages, and location information.
