Man-In-The-Middle Attacks against Wi-Fi
Wireless network communication via Wi-Fi has today become a taken-for-granted part of everyday life. Especially on mobile devices such as smartphones, the technology is used in a wide variety of ways—for example, not only to connect the device itself to the Internet, but also to share mobile network connections with other devices. Despite the commonplace use of this technology, most users are not aware of the many security weaknesses that have in some cases been known to experts for decades.
Within the scope of this project, the concrete scenario of Internet sharing via Wi-Fi tethering was used to investigate to what extent the network stacks of current smartphones are affected by known Wi-Fi security weaknesses, and which attacks are enabled as a result. In this report, we describe three different attacks and their implementation, evaluate them in the given scenario, and compare their characteristics. Finally, we discuss possibilities for detecting and preventing these attacks.
