A blog notes that two hackers at the Black Hat security conference are demonstrating a security flaw in the Macbook's device driver that would allow them to "seize total control over the machine".

...this attack can be carried out whether or not a vulnerable targeted laptop connects with a local wireless network. It is, they said, enough for a vulnerable machine to have its wireless card active for such an attack to be successful.

Similar vulnerabilities have also been found in corresponding Windows wireless drivers but the two are demoing the vulnerability on the Mac due to Apple's recent advertising on Mac OS X's security.

The vulnerability has not been described to be "in the wild", and the two have been in touch with Apple, Microsoft and other companies responsible for the drivers.
