Intercepting BlackBerry Communication
Most BlackBerrys come equipped with a 3G mobile-data wireless-connectivity interface, such as EvDO. In addition, most have Bluetooth capability and some even have Wi-Fi capability. It is important to realize that these interfaces are actually transmitting data to and from the BlackBerry device. This data could be sensitive and needs to be protected.
Not all of these interfaces transmit data in a linear fashion. The data does not go directly from point A to point B. Rather, the data is like a radio wave, transmitting in many different directions and potentially accessible to anyone within range. Think about how dangerous that could be. If a person is using a mobile device in an airport, many people and systems could potentially see what is going to and coming from the device. Figure 3.14 shows how this can take place.

When it comes to intercepting BlackBerry communications, the key is to know the following:
■■ What is being transmitted and received ■■ How it is being transmitted and received ■■ How to best control the transmission and reception ■■ How to best protect the transmission and reception
