Bluetooth-related threats

Bluetooth allows you connect your mobile phone wirelessly to another mobile phone or your computer. Although convenient Bluetooth entails security risks. Users of other Bluetooth devices within a range of 10 metres can download information from your mobile phone or send viruses to your mobile phone. However, this is only possible if you authorise your device to connect with the device of the person requesting such a connection.

Protecting your mobile phone

  • Only activate Bluetooth if you need it.
  • Assign a user name to your mobile phone.
  • Activate the “invisible” or “hidden” mode and deactivate the options “Automatically” and “Search”.
  • Reject unknown Bluetooth connection requests.
  • Delete unexpected messages received via Bluetooth immediately (without opening them).
  • Reject prompts by untrustworthy sources to install software or download files.

Securely linking your mobile phone to another device

Linking means connecting two Bluetooth devices for the first time (e.g. your mobile phone and new headphones). It is important that you adhere to the following security measures:

  • Do not link any Bluetooth devices in a public environment.
  • Only link your device with known Bluetooth devices and trustworthy partners.
  • Do not enter the PIN if an unknown partner requests to be linked to your device.
