Bluetooth connectivity is a convenient, useful technology. From headphones, keyboards and input devices to data transmission and file sharing, virtually any connection type can be made wireless through its code.
Unfortunately, the wireless tech standard also has proven time and again to be a potential security disaster. For many security professionals, Bluetooth’s dangers aren’t worth the risk.
While Bluetooth connection standards do include security protocols, those protocols are often poorly implemented or plagued with bugs. The code is complex, and its implementation is often left to the manufacturers of Bluetooth devices. This means developers with little or no specific training with the technology are left to interpret complicated interactivity between devices.
It’s a recipe for disaster.
How Bluetooth Works Against You
Hackers take advantage of Bluetooth’s security challenges and exploit the connectivity for a number of attack types. In a “bluejacking” attack, for instance, a cyber attacker sends a “business card” to other nearby Bluetooth-enabled devices that, if those nearby users aren’t careful, can add the target to their trusted contacts, which allows subsequent messages to be opened automatically. “Bluebugging” enables additional remote functionality, allowing hackers to place calls and send texts directly from other Bluetooth-enabled devices.
Other common attacks that exploit Bluetooth connections are similar to those targeting network connections. Denial-of-service (DoS) attacks involve hackers crashing phones or mobile devices to interrupt their normal functioning. These are more annoying than anything else – a hacker will continuously request to pair with a device, bothering the owner and draining the device’s battery. Older device types are particularly vulnerable to this kind of attack.
Most security professionals have a simple piece of advice for users of Bluetooth-enabled devices: If you aren’t using the device, disable your Bluetooth connection. Some say to simply not enable it at all; wired connections are a much safer option.
For organizations that have enabled their workforce with mobile technology, Bluetooth connection may be a legitimate concern. If this is the case with your organization, Lunarline can make sure you’re set up with proper security protection and not daring cyber criminals to hack your devices.
