Why in News?

• It is a form of hacking that lets attackers access a device through its discoverable Bluetooth connection.
• Once a device or phone is bluebugged, a hacker can listen to the calls, read and send messages and steal and modify contacts.
• Bluebugging attacks work by exploiting Bluetooth-enabled devices.
• Once a connection is established, hackers can use brute force attacks to bypass authentication. They can install malware in the compromised device to gain unauthorised access to it.
• Once hacked, the attacker can make and listen to calls, read and send messages, and modify or steal your contacts.
• Any Bluetooth-enabled device including wireless earbuds are susceptible to such hacks.
• Bluebugging can happen whenever a Bluetooth enabled device is within a 10-metre radius of the hacker.
• Hackers can also use booster antennas to widen the attack range.
• Apps that enable users to connect to their TWS (True Wireless Stereo) devices or earbuds can record conversations.

How can one prevent bluebugging?

• Turning off Bluetooth and disconnecting paired Bluetooth devices when not in use,
• Updating the device’s system software to the latest version,
• Limited use of public Wi-Fi and
• Using VPN as an additional security measure.
• Monitor data usage for sudden spikes.
