Blue bugging

Why in news?

• Several smartphones have their Bluetooth settings on discovery mode as it is a default setting, making it easy for hackers to access the phones when they are within 10 metres from the device. This is done through a process called Bluebugging..

About Blue-bugging:

• Bluebugging 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.

How does Blue bugging work?

• Bluebugging attacks by exploiting Bluetooth-enabled devices. The device’s Bluetooth must be in discoverable mode, which is the default setting on most devices.
• The bluetooth enabled device must also be within a 10-metre radius of the hacker.
• 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 unauthorized access to it.
• Any Bluetooth-enabled device can be blue-bugged.
  • Wireless earbuds are also susceptible to such hacks. Apps that enable users to connect to their TWS (True Wireless Stereo) devices or earbuds can record conversations.
