Android phones on AT&T and Verizon vulnerable to attack2015-10-19 03:10 by Daniela

A group of South Korean researchers have found a security flaw that targets LTE wireless networks. The vulnerability has been announced in an advisory posted by the Carnegie Mellon University CERT database.
Owners of Android devices who use AT&T or Verizon's wireless networks may be affected by the bug. It turned out that the LTE implementation by those carriers could expose millions of handsets to eavesdropping, data spoofing and over-billing.
The problem stems from the fact that LTE uses packet switching instead of older circuit switching to transfer data over the Internet. The new packet switching allows hackers to exploit the SIP protocol which is widely used in voice calls and instant messaging to gain access to a victim's device. After that attackers can execute denial of service (DDoS) attacks on a wireless network.
Android devices on other carriers like T-mobile seem not to be affected by the vulnerability. Currently, there is still no patch for the flaw.
