Rep. Ted Lieu is no stranger to having his cellphone "hacked." Intruders recently were able to track his whereabouts, eavesdrop on conversations with staff members and access his text messages and email.
Fortunately for Lieu, the intrusion was part of a 60 Minutes segment last year that the TV news program did to highlight mobile device vulnerabilities. The California Democrat knew of the hackers who had successfully exploited his phone's Signaling System Seven, aka SS7, security flaw that compromises the global network that connects phone carriers. The same vulnerabilities still exist one year later, Lieu shared on Thursday during a Capitol Hill demonstration about mobile security, or lack thereof.
