A group of researchers revealed that it is possible to crack the encryption used by satellite phones. All that is required is a common computer, a radio, and a few hundred dollars. The researchers were able to use a known-plaintext attack to decrypt messages sent and received over a satellite network. If a hacker wants to intercept the calls of others, he only needs a satellite phone. A recent study published in Science by researchers in the UK found that it is possible to track a satellite phone's location. If a trained technician can identify the radio frequency emissions, they can monitor the location of a mobile user. If they know where the phone is, they can track it and use it to intercept calls. Moreover, a satellite phone's coding can be broken in a fraction of a second, allowing for live eavesdropping.
