BlueChop

BlueChop is an attack that the disrupts any established bluetooth piconet by means of a device that is not participating the piconet. A precondition for this attack is that the master of the piconet supports multiple connections (a feature that is necessary for building up scatternets).

Method

In order to BlueChop a piconet, a device that is not participating this piconet spooofs a random slave out of the piconet and contacts the master of the piconet. This leads to confusion of the master's internal state and disrupts the piconet. This attack is not specific to any device manufacturer and seems to have general validity.

People Involved
