This adds a degree of validation to the "Just Works" pairing. If the PINs match on both devices, the user must then accept the connection for the devices to be paired. Once pairing is requested a PIN is shared between the devices. Numeric Comparison. Numeric Comparison is the most similar to legacy pairing.This is the simplest method and is used largely by devices lacking a UI. Just Works. The "Just Works" method does exactly what it says on the tin: one device requests a pairing and the devices are paired.

This has been replaced by the Secure Simple Pairing protocol (SSP) which provides three methods of Bluetooth pairing: There are known weaknesses in the legacy pairing protocols and legacy pairing also makes it difficult to pair devices that don't have a user interface (such as headphones). Legacy pairing allows devices to connect to each other using a shared PIN. Pairing of devices can be done in a number of ways. The requirement for pairing is set at the application level and can be used to prevent an unknown user from controlling Bluetooth applications on a device without authorization. The process of pairing creates a trust relationship between the devices, however, this is not completely necessary for Bluetooth to work. Most people are familiar with pairing of Bluetooth devices. This is represented by a 48-bit number, usually presented as 6 hexadecimal numbers separated by colons (for example 11:22:33:44:55:FF). These are assigned when manufactured and are used by Bluetooth protocols to determine which device is being interacted with.

OSIīluetooth devices have unique addresses, similar to the MAC address of a network adaptor. Bluetooth is an umbrella term for a range of standards and can be compared with the OSI model for conventional networking. The concept of "Bluetooth" as a whole can be compared to that of "the internet". In reality, Bluetooth is a range of technologies, protocols and standards that, when combined, create a means of sharing data between devices wirelessly over a short distance. When Bluetooth is mentioned, most people think of it as a single technology for connecting devices together. Of the three we tested, the only vulnerable system was the Polycom Trio 8500.Īll three devices allowed you to connect a mobile phone via Bluetooth and all allowed you to dial from the conference phone using the mobile to make the call. We took some time to look at three available solutions.
Specifically, we wanted to see if it would be possible to intercept communications through insecure Bluetooth configurations. The chances are that you have Bluetooth enabled devices near you as you read this, and, if you're regularly involved in conference calls, you've probably often used a Bluetooth enabled speaker or VoIP phone.Īdding technology to devices only increases the attack surface and, here at Cyberis, we decided to look at how Bluetooth might change the attack surface of VoIP devices. From smart phones to wireless speakers, fitness trackers to WiFi mesh hardware, Bluetooth has become the de facto standard for short-range wireless communications. Bluetooth technology permeates the modern world.
