Over the last few years, IEEE 802.11 standard for wireless connectivity usage has turned massive. Wireless devices are everywhere, from your smartphone to the printer that is in your office. As a matter of fact, all connected devices have proliferated at an incredible rate. IEEE 802.11 standard has many versions and 3rd party extensions bringing new features that add complexity to the protocol. This complexity makes platform implementations and drivers more intricate, opening opportunities for attackers. This presentation will show how attackers could use these features to fingerprint devices, abuse bad implementations to access devices with no credentials and how researchers could analyze 802.11 implementations on platforms such as Android and iOS for bug hunting.
