The experts say that mobile network infrastructure needs a serious security upgrade. This has become more of a concern until the NSA scandal broke. Security experts can demonstrate with just about any cell phone on the market how easy it is to tap into personal data and conversations: with the help of freely available programs. There are also spy apps that, once installed on smart phones, can transmit all of the data - undetected. Whoever installs the app can hear all conversations, activate the camera and track the user's location.
