I already explained the basics of Bluetooth technology in my first article in this series, and even showed off how Elliot used Bluetooth hacking in Mr. Robot. In this article, we will examine the use of the MultiBlue Dongle.
This dongle is capable of connecting to any Bluetooth device and enabling you to use your computer keyboard to control the device. Ostensibly developed and sold to enable users to use their computer keyboard and mouse on their mobile device, as you can imagine, it can be used for more surreptitious activities. It's available from many retailers including Amazon.com for about $35
In this tutorial, we will need physical access to the device, but as we expand and deepen your knowledge of Bluetooth, we will work toward using this dongle to control Bluetooth devices without physical access.
Although Bluetooth is limited to 10-100 meters, that is more than enough to cover most homes, neighborhoods, offices, libraries, schools, coffee shops, etc. With an antenna, this range can be extended. Now let's see how to connect to an Android device and control it via your computer keyboard.
