FCC to take look at mobile network's security

The Federal Communications Commission will examine a mobile network with a reported security flaw that is said to allow hackers to listen to customers' phone calls. Admiral David Simpson, the chief of the FCC's public safety bureau, said that the agency's Communications Security, Reliability and Interoperability Council would be asked to examine the challenges posed by a flay in the network, called SS7. The network helps connect calls, among other functions.
