Did you hear about the hackers who took control of a MacBook via the Wireless Card?

Well, it turns out that the report was at least partially a fraud. It turns out that the hack was not done to the AirPort card inside of the MacBook, but rather to a third-party USB wireless adapter. And the hack has only been accomplished against a third-party driver for the third-party USB wireless adapter. No one has been able to reproduce the hack on the onboard wireless system, nor with an Apple wireless driver.

So, to summarize, unless you happen to be the 1% of 1% of 1% who uses a third-party USB wireless adapter on a laptop with a perfectly good internal wireless card, this is nothing to worry about.
