I'm posting this merely so that I can make it clear that the exploit requires the user to plug in a -third party- wireless card to a computer that comes standard with an internal wireless card.
As someone on Slashdot mentioned:
What's next, writing the exploitable drivers themselves and claiming a vulnerability?
Daring Fireball also has a good summary of the BS that this is:
Two guys misrepresenting reality to make an exploit seem as though it's built into the system when it's not.
They apparently want to stab smug mac users in the eye -- but this isn't the way to do it.
UPDATE
Apparently the discoverers of the exploit (and the author of the articles) are now calling BS on those who call BS on their article.
John Gruber follows up on his original call-out with new accusations of shoddy reporting:
His points are pretty deadly, as always.
