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.
Various researchers have shown in the past that these devices are not secure and it is possible to compromise these devices. However, nobody has actually published further attacks that utilized the device. We will give a short introduction to femtocell technology and show different attacks based on a rogue femtocell. These attacks can target end-users being logged into a femtocell, femtocell owners, as well as network operators.
