Bluetooth technology is great. No doubt. It provides an easy way for a wide range of mobile devices to communicate with each other without the need for cables or wires. However, despite its obvious benefits, it can also be a potential threat for the privacy and security of Bluetooth users (remember Paris Hilton?). If you are planning to gain a deeper understanding of Bluetooth security, you will need a good set of tools with which to work. By familiarizing yourself with the following tools, you will not only gain a knowledge of the vulnerabilities inherent in Bluetooth- enabled devices, but you will also get a glimpse at how an attacker might exploit them. This hack highlights the essential tools, mostly for the Linux platform, that can be used to search out and hack Bluetooth- enabled devices. Discovering Bluetooth Devices BlueScanner - BlueScanner searches out for Bluetooth- enabled devices. It will try to extract as much information as possible for each newly discovered device. BlueSniff - BlueSniff is a GUI-based utility for finding discoverable and hidden Bluetooth- enabled devices. BTBrowser - Bluetooth Browser is a J2ME application that can browse and explore the technical specification of surrounding Bluetooth-enabled devices. You can browse device information and all supported profiles and service records of each device. BTBrowser works on phones that supports JSR-82 - the Java Bluetooth specification. BTCrawler - BTCrawler is a scanner for Windows Mobile based devices. It scans for other devices in range and performs service query. It implements the BlueJacking and BlueSnarfing attacks.
