U.S. Carriers unusually quiet after 60 Minutes' piece on hacking11
The congressman, U.S. Rep. Ted Lieu (D-Calif.), is now calling for an investigation into SS7, which is used to help different networks exchange information. It employs the use of a separate digital channel for sending information that allows different carriers to connect calls around the world.
The CTIA, the industry trade group that represents top carriers in the U.S., pointed out that for the 60 Minutes segment, the researchers "were given extraordinary access to a German operator's network to demonstrate the vulnerability." According to John Marinho, CTIA's vice president of cybersecurity and technology, "U.S. wireless providers remain vigilant to protect their networks and their customers." The problem with the CTIA's statement is that the congressman was using a U.S. carrier when his phone was hacked into.
Verizon, AT&T, T-Mobile and Sprint are refusing to comment on the television footage. Verizon and AT&T referred to the CTIA's statement while the other two carriers had no response.
