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
