The Threat Of Bluetooth Hacking
Bluetooth hacking, also known as Bluesnarfing, is a type of cyber attack where an attacker gains unauthorized access to a device through its Bluetooth connection. This can happen when a device is in discoverable mode, allowing nearby devices to detect and connect to it. In the case of car Bluetooth, this means that if your phone is connected to your car’s infotainment system, a hacker may be able to exploit this connection to gain access to your phone’s data.
The risks are real, and they’re growing. In 2019, a security researcher discovered a vulnerability in certain car infotainment systems that allowed hackers to take control of the system, including accessing the connected phone’s data. The vulnerability affected several major car manufacturers, including Fiat Chrysler, Ford, and Toyota.
How Bluetooth Hacking Works
Bluetooth hacking typically occurs through one of two methods:
1. Bluesnarfing
Bluesnarfing involves an attacker searching for nearby devices with Bluetooth enabled. Once a device is detected, the attacker can attempt to connect to it without the owner’s knowledge or consent. This can be done using specialized software or devices that can sniff out and connect to Bluetooth signals.
2. Bluejacking
Bluejacking is a less severe form of Bluetooth hacking, where an attacker sends unsolicited messages or files to a nearby Bluetooth device. While not as malicious as Bluesnarfing, Bluejacking can still be annoying and potentially damaging if the attacker sends malware or viruses.
