Adventures in Femtoland - 350 Yuan for Invaluable Fun

Explore the vulnerabilities in GSM, 3G, and LTE networks in this Black Hat conference talk. Dive into the evolution of mobile network security, from passive sniffing of unencrypted 2G traffic to the challenges of intercepting 3G and LTE communications. Learn about the potential risks associated with femtocells and how they can be exploited to create a "UMTS-in-a-box" solution. Discover the process of unboxing, modifying, and using femtocells to intercept data and expose vulnerabilities in UMTS networks. Gain insights into key protocols and technologies such as HNB, SeGW, HMS, RANAP, SCTP, and TR-069. Understand the implications of these security issues for telecom providers and mobile users alike in this 48-minute presentation by Alexey Osipov and Alexander Zaitsev.
