Researchers Hack Wi-Fi Driver to Breach Laptop

Robert McMillan writes on InfoWorld:

Security researchers have found a way to seize control of a laptop computer by manipulating buggy code in the system's wireless device driver.

The hack will be demonstrated at the upcoming Black Hat USA 2006 conference during a presentation by David Maynor, a research engineer with Internet Security Systems and Jon Ellch, a student at the U.S. Naval postgraduate school in Monterey, California.

The two researchers used an open-source 802.11 hacking tool called LORCON (Lots of Radion Connectivity) to throw an extremely large number of wireless packets at different wireless cards. Hackers use this technique, called fuzzing, to see if they can cause programs to fail, or perhaps even run unauthorized software when they are bombarded with unexpected data.

Using tools like LORCON, Maynor and Ellch were able to discover many examples of wireless device driver flaws, including one that allowed them to take over a laptop by exploiting a bug in an 802.11 wireless driver. They also examined other networking technologies including Bluetooth, Ev-Do (EVolution-Data Only), and HSDPA (High Speed Downlink Packet Access).
