Developing an Open-Source Wi-Fi De-authenticator Using Network Capable System-on-Chip Devices

Abstract

In response to the growing security concerns about unauthorised access to wireless networks, the project seeks to provide an understanding of the underlying workings and preventative measures of de-authentication. This thesis showcases the design, implementation, and results of an open-source IEEE 802.11 WLAN de-authenticator that makes use of System-on-Chip devices with network capability.

The methodology consists of the development of software for System-on-Chip devices, with efficient manipulation and transmission capabilities necessary for de-authentication attacks. The key components of the system include a core package used for manipulating IEEE 802.11 into de-authenticating victims, as well as an intuitive user interface for setting up and executing de-authentication attacks. Also, the implementation follows open-source principles, having zero proprietary parts.

The outcome of the project was decided by rigorous testing in diverse network environments, evaluating its effectiveness, reliability, and performance. Overall, this thesis presents the flaws in IEEE 802.11, as well as how bad actors can take advantage of them through de-authentication
