AdaptiveMobile Security has detected a unique and novel mobile core network vulnerability that is currently being exploited by a sophisticated attacker in multiple countries for surveillance reasons. This exploit represents arguably one of the most complex and sophisticated attacks ever seen over mobile core networks. The observed attack involves the remote retrieval of specific information, such as location information, without the awareness or interaction of the mobile phone user. The vulnerability can also be used to perform additional types of attacks, such as denial of service, fraud, and other forms of information harvesting.
In this session, we will explain the vulnerability and how it is exploited. To begin, we will cover how the vulnerability works structurally, and its technology underlay. Then we will discuss its potential reach, which operators and which countries could be affected, along with an idea of where we have actually seen attacks occurring. We will then give some intelligence overviews - i.e. who we think is exploiting it, and why. We will also show the attack's evolution over time, and the reaction of the attackers to their activity being detected and blocked, both on our side and at an industry level. Finally, we will show what we found to be the best ways to detect and block related attacks, and provide tactical recommendations for the future to deal with the evolution of mobile network attacks.
