While Bluetooth has become a ubiquitous part of our daily lives, a majority remain unaware of its inner workings and, more importantly, its susceptibility to hacking. Delving into the realm of Bluetooth hacking provides a direct glimpse into the target's world. Given that nearly every device is equipped with Bluetooth capabilities, exploiting this wireless technology could potentially grant access to a wealth of personal information stored on phones and tablets.
Despite Bluetooth and Wi-Fi sharing the same 2.4 GHz frequency, their distinct protocols render them different entities in terms of security. Bluetooth's heightened security measures make conventional Wi-Fi hacking tools ineffective against it.
One notable feature is the continuous frequency hopping employed by Bluetooth devices. When two devices communicate via Bluetooth, they utilize an algorithm that dynamically shifts the frequency multiple times per second. This constant frequency hopping poses a significant challenge for potential attackers attempting to eavesdrop on the communication.
Additionally, Bluetooth differs from Wi-Fi in how it handles key negotiation. While Wi-Fi negotiates a key with every connection, Bluetooth establishes a key only once during the initial connection. Subsequently, this secret key is stored and referenced for subsequent communications with the same device. Unlike Wi-Fi, this approach makes it virtually impossible for an attacker to passively sniff the key, as they would need to be present during the initial communication.
However, this doesn't mean Bluetooth is impervious. It is still susceptible to tracking nearby devices, extracting information from them, and even manipulating specific characteristics. Conducting reconnaissance becomes crucial, as it may unveil opportunities to seize control, identify vulnerabilities, or discover potential exploits that align with nearby devices.
Understanding the nuances of Bluetooth technology is vital not only for users but also for those tasked with securing these wireless connections in an ever-evolving digital landscape.
Preparing for Bluetooth Reconnaissance: A Quick Guide
Embarking on Bluetooth surveillance requires a well-equipped setup. Ensure you have an up-to-date installation of Kali Linux, as we'll leverage its built-in Bluetooth tools for this endeavor. Keeping it streamlined, we won't be adding any extra tools; the default Bluetooth toolkit in Kali Linux will suffice.
Key tools included in BlueZ, the default Bluetooth protocol stack in most Linux versions, form the foundation of our exploration. Among these, we'll delve into hciconfig, hcitool, sdptool, l2ping, and btscanner. Additionally, specialized tools tailored for Bluetooth reconnaissance in Kali Linux will be introduced.
Proximity is a critical factor in Bluetooth hacking. Armed with a reliable Bluetooth adapter, you can target devices in various settings—be it a coffee shop, school classroom, office, or even within close proximity of a neighbor's house. Ensure your Bluetooth adapter is of high quality to maximize the reach of your Bluetooth reconnaissance.
Activating Bluetooth Adapter: A Primer with hciconfig
Much like ifconfig serves for Wi-Fi, the counterpart for Bluetooth devices is hciconfig. This tool facilitates the activation of your Bluetooth adapter, serving as the initial step in our reconnaissance journey. Familiarize yourself with hciconfig to set the stage for efficient Bluetooth hacking.

In this guide, we'll navigate the setup of your Bluetooth interface, an essential precursor for efficient Bluetooth hacking. Observe our example, where the Bluetooth interface is currently inactive (down). Follow these steps to bring it to life and initiate your Bluetooth operations. Suppose you are well-acquainted with ifconfig commands. In that case, adapting to hciconfig will be seamless, as they share a structural resemblance. For instance, if you need to activate a Wi-Fi interface, the command is "ifconfig [interface_name] up". In the realm of Bluetooth, using hciconfig mirrors this process. Explore the hciconfig man page for a comprehensive list of compatible commands.

BlueZ Nov 12 2002 HCITOOL(1)
Manual page hcitool(1) line 154/176 (END) (press h for help or q to quit) Hcitool proves invaluable in configuring and executing diverse tasks such as scans, inquiries, and name retrieval. However, certain commands necessitate the use of MAC addresses. A fundamental operation is scanning for nearby Bluetooth devices, providing MAC addresses for further inquiries or attempts to extract device names. Initiate a scan with the command hcitool scan. This employs the Bluetooth interface to identify nearby devices, revealing their MAC addresses. This information serves as a gateway for subsequent scans, inquiries, or endeavors to unveil device names.
~# hcitool scan
Scanning ...
00:1D:A5:00:09:1D OBDIIAbove, we see an OBD2 connector which is connected to a vehicle. That’s pretty interesting. With the MAC address, we can now we can do another command that required us to have a MAC address in the first place. Let’s try getting the name of the device:
~# hcitool name 00:1D:A5:00:09:1D
OBDII
That should allow us to get the name of the device, but we already knew it from that first scan. If we didn’t know it, however, it’ll allow us to be able to learn more about it. To learn more, we can use the inq command:
~# hcitool inq 00:1D:A5:00:09:1D
Scanning ...
00:1D:A5:00:09:1D clock offset: 0x21c0 class: ox5a020cNote that it also displays clock offset and the class. The class indicates what type of Bluetooth device it is, and we can look up the code by going to the Bluetooth site. Or, as we will see later, some tools will do it for us.

Now, let's shift our focus to the final tool in our arsenal—a full-fledged graphical user interface designed for Bluetooth device discovery. It goes by the name btscanner. To initiate it, simply type btscanner. Before proceeding, let's quickly review the man pages for this tool as well.
~# man btscanner
BTSCANNER(1) General Commands Manual BTSCANNER(1)
NAME
btscanner - ncurses-based scanner for Bluetooth devices
SYNOPSIS
btscanner [--help] [--cfg ] [--no-reset]
DESCRIPTION
This manual page was written for the Debian GNU/Linux distribution be‐
cause the original program does not have a manual page.
btscanner is a tool designed specifically to extract as much informa‐
tion as possible from a Bluetooth device without the requirement to
pair. A detailed information screen extracts HCI and SDP information,
and maintains an open connection to monitor the RSSI and link quality.
btscanner is based on the BlueZ Bluetooth stack, which is included with
recent Linux kernels, and the BlueZ toolset. btscanner also contains a
complete listing of the IEEE OUI numbers and class lookup tables. Using
the information gathered from these sources it is possible to make edu‐
cated guesses as to the host device type.
OPTIONS
--help Show a help text and exit.
--cfg Use as the config file.
--no-reset Do not reset the Bluetooth adapter before scanning.
BUGS
Please report any bugs to Tim Hurman .

Opening the OUI database
Reading the OUT database
Although many use Bluetooth daily, its workings and vulnerabilities often remain unknown. Hacking Bluetooth provides access to vast personal data stored on phones and tablets. Unlike Wi-Fi, Bluetooth devices hop frequencies, making it challenging for attackers to intercept communication. Additionally, Bluetooth negotiates a key once, enhancing security. With built-in tools on Kali Linux, Bluetooth reconnaissance becomes accessible. Tools like hciconfig, hcitool, sdptool, l2ping, and btscanner enable device discovery, service exploration, and ping tests. Bluetooth hacking demands proximity, and a compatible adapter enhances reach. Execute these steps responsibly, respecting legal and ethical boundaries.
