Summary : The control and management of mobile networks is shifting from manual to automatic in order to boost performance and efficiency and reduce expenditures. Especially, base stations in today's 4G/LTE networks can automatically configure and operate themselves which is technically referred to as Self Organizing Networks (SON). Additionally, they can auto-tune themselves by learning from their surrounding base stations. This talk inspects the consequences of operating a rogue base station in an automated 4G/LTE network. We exploit the weaknesses we discovered in 4G/LTE mobile phones and SON protocols to inject malicious packets into the network. We demonstrate several attacks against the network and discuss mitigation from the mobile network operators perspective.
