What is Bluebugging and how do hackers use it? Learn how to secure your devices

Bluebugging attacks take advantage of Bluetooth-enabled devices. Bluebugging is a process of hacking through which hackers can gain access to devices with discoverable Bluetooth connections. According to independent security researcher Martin Herfurt, the bug used a Bluetooth protocol flaw to retrieve call logs and phone books from the device of the targeted user. Some methods to avoid bluebugging include disabling Bluetooth and removing paired Bluetooth devices when not being used, updating the system software on the device, restricting the use of open WiFi, and employing a VPN as an additional layer of security. The majority of devices set Bluetooth discoverable by default, leaving your devices open to unauthorized connections.
