Bluetooth Users Beware!

Bluetooth Users Beware!

Bluetooth technology helps simplify our daily lives -- it allows for hands free communication, a quick and easy way to share content with friends, family, colleagues, and more. In fact, 45 percent of Americans have Bluetooth enabled across multiple devices. This raises the question: Does using Bluetooth leave our doors opened to hacker attacks?

Google paid a settlement fee of $7-million for unauthorized data collection from unsecured wireless networks in 2013. While their intention likely wasn’t theft, many disagreed and called them out for Bluesnarfing, a method most hackers are familiar with.

What is it?

Bluesnarfing is the use of Bluetooth connection to steal information from a wireless device, particularly common in smartphones and laptops. Using programming languages that allow them to find Bluetooth devices left continuously on and in “discovery” mode, cyber-criminals can attack devices as far as 300-feet away without leaving any trace.

Once a device is compromised, hackers have access to everything on it: contacts, emails, passwords, photos, and any other information. To make matters worse, they can also leave victims with costly phone bills by using their phone to tap long distance and 900-number calls.

What preventive measures can you take?

The best way is to disable Bluetooth on your device when you’re not using it, especially in crowded public spaces, a hacker’s sweet spot. Other ways to steer clear of Bluesnarfing include:

  • Switching your Bluetooth to “non-discovery” mode
  • Using at least eight characters in your PIN, as every digit adds approximately 10,000 more combinations required to crack it
  • Never accept pairing requests from unknown users
  • Require user approval for connection requests (configurable in your smartphone’s security features)
  • Avoid pairing devices for the first time in public areas

Bluesnarfing isn’t by any means the newest trick in a cyber-criminal’s book, but that doesn’t mean it’s any less vicious. If you’d like to know more about how to keep your IT and your devices safe, give us a call and we’ll be happy to advise.
