802.11 Protocol Chaos
Category: Vulnerability Research
Summary: 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.
IEEE 802.11 standard has many versions and 3rd party extensions bringing new features that add complexity to the protocol. Modern devices support several specifications such as Cisco Client Extensions, WiFi Protected Setup, WiFi Direct, AirPlay and AirDrop (just to mention a couple of them). This complexity makes platform implementations more intricate, opening opportunities for attackers.
This presentation will show how attackers could use these specifications to fingerprint devices, abuse of bad implementations to access devices and get internal network information without even connecting to the network.
