With the popularity of smartphones and the utilization of Bluetooth for communication and data transfer, three-quarters of mobile phone users are not even aware of the internet security risks linked to Bluetooth-equipped devices. Bluetooth is an open standard for short-range radio frequency communication. Bluetooth technology is used primarily to establish wireless personal area networks (WPANs), and it has been integrated into many types of business and consumer devices.  Utilizing Bluetooth has its risks and they can be categorized into four main semblances:

  • Bluejacking is when anonymous text messages are sent to mobile phones
  • Bluespamming is when a phone’s contacts are secretly sent text messages
  • Bluesnarfing is when hackers gain access to a mobile phone’s contacts
  • Bluebugging is when hackers have access to a handset’s commands

While each of these risks is a nuisance, Bluesnarfing and Bluebugging can be very serious. With bluesnarfing, hackers can gain access to stored data on your smartphone, such as a phonebook, calendar or they can even use the data discovered to clone your phone.

Bluebugging, on the other hand allows hackers to make phone calls from the mobile phone they control. They can write messages and send them from the phone and they can even eavesdrop on private conversations.

Even though you think it can never happen to me, you should take some simple precautions to protect yourself against Bluetooth security breaches on your mobile phone such as always disable Bluetooth functionality on your phone when it’s not in use and investing in some mobile antivirus software available for you particular phone.  Though not fool-proof, they will help to mitigate risks associated with Bluetooth communication.
