Novatel's MiFi portable 3G to Wi-Fi router has become very popular among carriers, many of which are now selling rebranded version of the devices to their 3G customers (both Sprint and Verizon sell the unit as the MiFi 2200). According to Security researcher Adam Baldwin however, the device's security leaves a little something to be desired. A number of attacks can provide an attacker not only with control of the unit, but access to the GPS location of the MiFi device without the user becoming immediately aware. The attack can be executed without authentication and even if the GPS has been disabled by the administrator.
