Blue Bugging

In News 
  • According to some app developers, any app with access to Bluetooth can record users’ conversations when using headsets/earplugs, through a process called bluebugging.
Blue Bugging 
  • 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.
  • It started out as a threat to laptops with Bluetooth capability.
  • Later hackers used the technique to target mobile phones and other devices.
Threats 
  • Bluebugging attacks work by exploiting Bluetooth-enabled devices.
  • The device’s Bluetooth must be in discoverable mode, which is the default setting on most devices.
  •  The hacker then tries to pair with the device via Bluetooth. Once a connection is established, hackers can use brute force attacks to bypass authentication. 
  • They can install the malware in the compromised device to gain unauthorised access to it. Bluebugging can happen whenever a Bluetooth-enabled device is within a 10-meter radius of the hacker.
Prevention 
  • Turning off Bluetooth and disconnecting paired Bluetooth devices when not in use, updating the device’s system software to the latest version, limiting use of public Wi-Fi, and using VPN as an additional security measure are some of the ways to prevent bluebugging, 
  • Users must also watch out for suspicious activities on their devices.
