4G/LTE networks are more secured than the previous generations. This talk discusses a research platform we built using open-source tools to investigate security of 4G/LTE networks and devices in practice. We show how popular smartphones available in the market leak information to a fake base station. In addition, we demonstrate our low-cost 4G/LTE IMSI catcher for the purpose of practical telecommunication security research.
