In recent years there has been increased concern over Bluetooth security. While Bluetooth is incredibly convenient, it’s also the source of many security lapses.
The problem is that Bluetooth is the invisible glue that connects devices. When it gets buggy that affects everything from Android devices and iPhones to the physical authentication keys needed to secure other accounts.
The magnitude of Bluetooth security problems is far reaching. Take the BlueBorne flaw, first discovered in September 2017. BlueBorne bugs permit attackers in worst-case scenarios to gain complete control of both a device and any data stored within. The airborne attack is difficult to protect against as it does not spread over an IP connection, and traditional anti-virus solutions are no defense. BlueBorne immediately impacted 5 billion PCs, phones and IoT (Internet of Things) units.
Of course, with any computing standard, there’s always the possibility of vulnerabilities in the actual code of the Bluetooth protocol itself. But security researchers say that the big reason Bluetooth bugs come up has more to do with sheer scale of the written standard—development of which is facilitated by the consortium known as the Bluetooth Special Interest Group.
In other words, Bluetooth offers so many options for deployment that developers don’t necessarily have full mastery of the available choices, which can result in faulty implementations.
Bluetooth opens up a channel for two devices to communicate—an extremely useful arrangement, but one that also opens the door for dangerous interactions. Without strong cryptographic authentication checks, malicious third parties can use Bluetooth to connect to a device they shouldn’t have access to, or trick targets into thinking their rogue device is a trusted one.
