What is Bluebugging?

  • It is a form of hacking that lets attackers access a device through its discoverable Bluetooth connection.
  • Once a device or phone is blue-bugged, a hacker can listen to the calls, read and send messages and steal and modify contacts.
  • It started out as a threat for laptops with Bluetooth capability. Later hackers used the technique to target mobile phones and other devices.
  • He noted that the bug exploited a loophole in Bluetooth protocol, enabling it to download phone books and call lists from the attacked user’s phone.
  • Even the most secure smartphones like iPhones are vulnerable to such attacks.

Preventive Measures:

  • Turning off Bluetooth and disconnecting paired Bluetooth devices when not in use,
  • Updating the device’s system software to the latest version,
  • Limiting the use of public Wi-Fi, and
  • Using VPN as an additional security measure
