    Roman Unuchek This story began a few months ago when I got a popular brand of fitness bracelet. As this is a wearable device I installed Android Wear app , an application developed especially for wearable devices. This application easily connects to the fitness band. After that I decided to do some research and find out how secure my wristband was. KSN provides the following statistics about the installation of Android-based applications to work with popular fitness trackers on mobile devices the statistical data was obtained from KSN users who freely agreed to the transfer of this data.

    The installation of Android-based applications designed to work with fitness trackers from different manufactures Although this statistic demonstrates the popularity of Android applications we cannot guarantee that the appropriate devices have users , to some extent it reflects the situation with the popularity of wearable devices.

    To communicate with the smartphone most of these fitness bands use Bluetooth LE technology also known as Bluetooth Smart. For us, this means that the devices connect in a different way from regular Bluetooth. In some cases you can connect to a wearable device without the owner even knowing Tweet These wristbands use a GATT Generic Attribute Profile which means that every wearable device includes a set of services, each of which has a set of characteristics.

    Each characteristic contains a byte buffer and a list of descriptors, and each descriptor contains a value — a byte buffer. I did not have to write a single new line of code; I simply opened the existing project in Android Studio and pressed Start. The screenshot above shows the result of my attempt to connect my fitness bracelet with the help of this application.

    Here we see the services and their characteristics. However, it is not easy to obtain data for my bracelet from the characteristics — it requires authentication in addition to the connection. In the case of some other devices I could read the data from the characteristics and their descriptors. This was probably the user data. After that I have developed my own application which automatically searched for the Bluetooth LE devices attempting to connect to them and get their list of services.

    Using this application I performed several scans. Over two hours on the Moscow undeground subway system I could have connected to 19 devices: 11 FitBit and 8 Jawbone.

    It seems that it is not possible to connect to a device that already has a connection to another phone. Thus if your wristband is connected to your phone, no one else can connect to it; it should not even be seen during scanning. The second restriction should mean that when the wristband is connected to a smartphone, it cannot be attacked. This is not true though. And here is an example: while scanning with my app I was able to block the communication between my bracelet and its official application, even though they were connected.

    It could be that the devices I found had never connected to a phone before or that the wristband was not connected to a smartphone while I was scanning perhaps the Bluetooth on the phone was disabled. However it could also be that a pre-connected device was still available for connection despite the supposed restriction.

    Whatever the reason, potential fraudsters have ample opportunity to connect to fitness trackers. However, in most cases, authentication is required in addition to the connection in order to gain access to the user data. After that one of the characteristics changes its value — the byte buffer. The application creates a new array. Its first part is a constant array which is contained in the application and begins with 6dcfd44; the second part of the new array is authBytes.

    The application receives the MD5 hash from the new array and sends it back to the device in the following structure: Header f Verification byte The application then sends to the device yet another array also found in this application.

    After this wristband starts to vibrate and the user just needs to press the button to complete the authentication process. With the official application the authentication process takes about 15 seconds. I have developed an application that requires only 4 seconds to make the wristband vibrate.

    It is not difficult to make the user press a single button on the wristband. You just need to be persistent. You can keep trying authentication process over and over until the user finally presses the button or moves out of range. From just six hours of scanning I was able to connect to 54 devices despite two serious restrictions Tweet After authentication is completed, the data on my bracelet can be accessed.

    Right now, wearable fitness devices do not contain much information. Typically, they have the number of steps, the phases of sleep, the pulse for the last hour or so.

    Approximately once an hour the app transfers this information from the wristband to the cloud. After the authentication, it is easy to execute commands on the device.

    Things are even easier with the other fitness trackers: for some of them, part of the data is available immediately after the connection, while the application code for Nike is not even obfuscated and can be easy read the results of one study can be found here.

    Conclusion The results of my research show that in some cases you can connect to a wearable device without the owner even knowing. By hacking the bracelet I have the fraudster cannot get access to all user data as this is not stored on the wristband or in the phone — the official application regularly transfers information from the wristband to the cloud. Fitness trackers are becoming more popular and offer a wider range of functions.

    Perhaps in the near future they will contain more sensors and hence much more user information, often medical data. However the creators of these devices seem to think very little about their safety. Just imagine — if a wristband with the pulse sensor is hacked, store owners could look at your pulse rate while you are looking at the prices in the store. It might also become possible to find out how people react to advertising. Moreover, a hacked wearable with pulse sensor could be used as a lie detector.

    The fraudster could take control of your wristband, make it vibrate constantly and demand money to make it stop Tweet Of course, there are more harmful actions that are more likely. For example, by using a Trojan-Ransom the fraudster could take control of your wristband, make it vibrate constantly and demand money to make it stop. For ethical and security reasons we are not disclosing the name and the model of the bracelet this time.

    We also hope that this article will be helpful not only for users but also for vendors of the bracelets to make these devices safer from the IT Security perspective.
