Protect Yourself From Bluesnarfing Attacks

What is Bluesnarfing?

Bluesnarfing is a type of cyberattack in which hackers exploit Bluetooth connections to access information on your device without your knowledge or consent. This can include contacts, emails, text messages, photos, calendar entries, and even sensitive data like passwords. In 2017, criminals planted small Bluetooth devices inside gas pumps. When customers swiped their cards, the devices collected their payment data and wirelessly transmitted it to attackers nearby, within just 30 feet.

How It Works

When your device’s Bluetooth is set to “discoverable”, nearby attackers (within ~10 meters) can detect it and exploit known vulnerabilities to silently steal your data. Common targets include smartphones, laptops, tablets, smartwatches, fitness trackers, wireless headsets, and other Bluetooth-enabled devices.
