In the contemporary society the rapid evolution of communication technologies, raise security and privacy issues for the users of 2G and 3G networks. Many attackers are able to crack or eaves drop a network and corrupt the communication channel. The object of the present thesis is to prove that it is feasible to collect security related data using just an application to achieve this. If we analyze these data, then security vulnerabilities of 2G and 3G networks will come to light. Security related data were extracted directly from SIM / USIM module, meaning that we acquired network attributes from the source. The extraction took place by establishing communication with the modem and sending AT Commands to it. Data will be stored and uploaded to a server for further handling. The application was developed in Android environment, using Android SDK and other development tools such as Eclipse IDE.
