Last weeks Intel Centrino issues where just the beginning. Today, Jon Ellch and David Maynor presented more wireless device driver issues at Blackhat. As a demo, they compromised a MacBook using one of the wireless device driver issues they discovered.

The highlights:

• This is less of an OS problem, but a firmware/driver issue. While the demo was done on a Mac, it would have worked on other OS's as well.
• Various wireless cards have problems, not just the once demoed at Blackhat.
• You do not have to be associated with a wireless network in order to be exposed.
• A firewall will not protect you.

What can you do:

• Turn off the wireless card (and bluetooth while you are at it).
• Watch for patches.
• To prepare for any patches, learn what type of wireless card you have.
