Mobile signaling threats and vulnerabilities – real cases and statistics from our experience
We have been exploring the security of mobile signaling for years. 2G, 3G and then 4G+, all the generations of protocols proved to be similarly vulnerable. However, the existence of vulnerability doesn’t automatically mean it is being exploited in the wild. Having conducted more than 60 security assessments for the mobile operators signaling networks, based on the experience of security monitoring projects, we gathered more than enough info to share with the world. What are the hackers up to? What is the state of networks security? How and which methods allow hackers to bypass evolving security measures? I will explore the most interesting cases in technical detail.
