But turning off Bluetooth will also turn off Covid track and trace. From least significant bit to most significant bit, here are the fields:. Remember though, always check your tools and do not rely on what they tell you - get multiple examples of the same process to help ensure you are sniffing the data accurately.
Here is a Pairing Reply packet during a pairing of an Apple Watch with an iPhone using the Passkey Entry process that illustrates this perfectly:. Figure 2. Wireshark interpretation of an Apple Watch pairing reply packet. Under the Wireshark interpretation, only the bits for Bonding and MITM are set, while the value of 0x0d suggests the Secure Connection bit is also set. This is in spite of the fact that the Keypress bit is not set.
My guess is the latter. During its Pairing Request packet, the iPhone did say that it can do 0x04 Display Screen and Keyboard for input , so when you consider everything the two devices are claiming they can do in the conversation, they can handle Passkey Entry.
It is specifically limiting itself during the pairing process to match what is being requested by the user, who is controlling the pairing choice. There is nothing in the specification about adjusting things to user preference or settings, although it makes sense, especially from a security perspective, to limit the amount of exposure. This is the level of scrutiny one needs when looking at Bluetooth to either prove or disprove an action or setting.
But at least you can make the statement firmly. Whenever a Bluetooth device needs to transmit, it enters an advertising mode where it announces to the world it is there.
Depending upon the nature of the device, it could do this only periodically, or it could be doing this constantly. It uses a MAC address during advertising so that other devices can potentially talk back to it.
Therefore, it makes sense that a device trying to protect its owner from tracking would periodically change its MAC address. Naturally, this creates other problems. How will the paired devices know what they are paired to if the address keeps changing?
How can I limit the knowledge of my MAC address to only devices I trust, while still protecting myself from being tracked? This is where LE Privacy comes in. This solution was introduced with the creation of Bluetooth Smart the 4. During the pairing process in phase three as outlined above , the devices exchange a variety of keys. This key allows for the creation and resolution of random MAC addresses to be used in advertising packets.
If you wanted to track a specific address, you'd have to visually locate that person's physical device and follow it around all day, which would easily blow your cover. And locating someone else's smartphone doesn't let you listen in on what they're doing or read their email.
But If several Bluetooth-enabled receivers are strategically placed to cover a large area, they can track the positions of any discoverable device, recording and sending any data back to a single address.
Each Bluetooth receiver acts like any regular Bluetooth device: It searches for every device within range. If a person walked down a meter-long foot-long street and each Bluetooth receiver had a range of 10 meters, five receivers with a radius of 20 meters 66 feet would be needed to track that person's movement.
As he walked toward the street, the first receiver would track him for the length of the first 20 meters, the second for the next 20 meters, and so on for the length of the street. So how have people used this system to track people? One of the earliest uses of Bluetooth positioning and tracking technology is the Aalborg Zoo, the largest zoological garden in Denmark, in The point of installing the system was not to put the zoo's patrons under surveillance or to see which exhibitions people went to more often.
Instead, special "Bluetags" were made available to prevent parents from losing valuable belongings that tend to wander off — their children. A parent could attach a "Bluetag" onto a child, and Bluetooth receivers around the zoo would track the child's movement. Bluetooth beacons hardware transmitters have become commonplace for customers to find their way around retail environments.
A shopping mall, for example, could install a Bluetooth surveillance system throughout its entire area to monitor the movements of Bluetooth owners. Although it wouldn't present a perfectly accurate description of a person's movement, the system could create a general map of his path and even compare how long someone stays in a certain area. For instance, in , Bluetooth reported that the giant Mall of America in Minneapolis was using its technology.
From there, the app can get customers moving in the right direction while providing additional information, such as store hours, estimated time of arrival, and vertical transportation factors like escalators that impact accessibility for shoppers utilizing strollers or wheelchairs," the company wrote. With this knowledge, store owners could analyze shopper's behavior and change advertisement positions accordingly without anyone ever knowing.
Some retailers use this surveillance to enhance services, knowing when a shopper with an appointment has arrived and where they are, even in a busy store. You may have been using this same technology without realizing it. Personal Bluetooth trackers such as the Tile series and Apple's AirTags are very helpful for finding things you misplace often, such as your keys. An app on your smartphone can tell you where they are, as long as they are near another Bluetooth device that can identify the tracker.
But this requires many people to have Bluetooth enabled. If you left your keys at your desk, your work neighbor's phone might be able to tell you right where they are. They're doing a kind of Bluetooth surveillance, and so are you — you've opted into the network of people looking for these trackers and passing on that info to someone who may have lost something important. During the COVID pandemic, several governments have used Bluetooth technology in tracking devices that citizens download on their phones.
In the case of Britain, if someone has tested positive for COVID and the person agrees , the National Health Service will send them a link where they should fill out the contact information names, addresses, phone numbers of anyone they have had contact with. Virtually all mobile devices with Bluetooth technology are susceptible. It gives hackers full control of the device and can be used to access corporate data and networks. BlueBorne can be used for cyberespionage, data breaches, ransomware campaigns, and even to make botnets out of other devices.
While patches have been rolled out for affected devices, BlueBorne showed how easily hackers can exploit Bluetooth technology and how much damage this can cause.
Here are a few ways to protect yourself from hackers who are trying to gain access to your device via Bluetooth. If you leave your Bluetooth on, it will keep looking for an open device within a range that it can connect with. Hackers wait for unsuspecting users who either forget to turn their Bluetooth off or leave it on for long periods.
This includes bank information, passwords, private photos, and other PII. Many attacks target Bluetooth devices that are within range and are discoverable. This is how they locate and zero in on the ones they can infiltrate. There are cybercriminals who have worked around this and are now able to attack even Bluetooth devices that are not discoverable.
However, these attacks are rarer, so you're limiting hackers' options. Do not accept pairing requests unless you are sure it's with a device you want to link to. This is how hackers gain access to the information in your device.
