Abstract

Wi-Fi has emerged as the technology of choice for Internet access. Thus, virtually every smartphone or tablet is now equipped with a Wi-Fi card. Concurrently, and as a means to maximize spectral efficiency, Wi-Fi radios are becoming increasingly complex and sensitive to wireless channel conditions. The prevalence of Wi-Fi networks, along with their adaptive behavior, makes them an ideal target for denial of service attacks at a large, infrastructure level.

In this talk, I will show how vulnerabilities in rate adaptation mechanisms can be used to mount reflection attacks on an entire Wi-Fi network. I will then present mitigating solutions and areas for future research. Finally, time permitting, I will present a Google Dork to quickly and remotely identify weak set-ups of Wi-Fi enterprise networks.
