Blue smacking is one of the older types of attacks against the protocol. In our investigation of this attack, you’ll find that it’s a variant of a common attack called denial of service against networks, devices, and applications. In short, when we perform a Blue smack attack, we perform a specially crafted package that can render a device unusable. This attack works by transmitting packets that exceed the maximum packet size available on the Bluetooth device. The end result is that the device is unable to process the packet and the target becomes a denial of service victim. This attack is a variation of the popular Death’s Flat attack.
