Femtocells are an emerging technology deployed by the operators around the world to enhance 3G connectivity. These secured devices are installed in the customers home and connect the mobile phone to the mobile network operator's core network using an existing broadband connection.
While various researchers (including us) have shown in the past that these devices are not secure and can be hacked, nobody has actually further utilized the device. In this presentation, we will give a short introduction to femtocell technology and show different attacks based on a femtocell targeting both end-users and network operators.
