Two privacy-minded Democrats, Rep. Ted Lieu and Sen. Ron Wyden, are pushing FCC chairman Ajit Pai to deal with what they say are major vulnerabilities in mobile phone networks:
The bigger picture: Lieu was involved in an attention-grabbing 60 Minutes segment last year where the show listened in on his communications with his permission. That particular vulnerability exists in a global calling network called Signaling System 7. The lawmakers' letter on Tuesday is responding to a recent report from an FCC working group launched to study the issues with SS7. "So that's the point, is trying to give a wake up call to the FCC," Wyden told reporters Tuesday.
