The Motorola PEBL U6, the Motorola V600, and possibly the Motorola E398 and other Motorola phones allow remote attackers to add an entry for their own Bluetooth device to a target device's list of trusted devices (aka Device History), and possibly obtain AT level access to the target device, by initiating and interrupting an OBEX Push Profile that pretends to send a vCard, aka a "HeloMoto" attack.

The Motorola PEBL U6 08.83.76R, the Motorola V600, and possibly the Motorola E398 and other Motorola P2K-based phones does not require pairing for a connection related to the Headset Audio Gateway service, which allows user-assisted remote attackers to obtain AT level access and view phonebook entries and saved SMS messages by connecting on Bluetooth channel 3 and tricking the user into pressing Grant, aka a "Blueline" attack. NOTE: while user-assisted, the attack is made more feasible because of a GUI misrepresentation issue that allows a default message to be replaced by an attacker-specified one.
