--"Machines are vulnerable if they have wireless enabled and are set to connect to any available wireless network". This is enough information to secure your system. Simply tell it not to connect to any available wireless network. Only allow it to connect networks you have specified. Tada. No cash needed for this fix.-- This is wrong. The exploit is designed to attack any wireless card that is actively scanning. It does not matter if you are on a trusted or untrusted wireless network. According to the researchers, right now the only way to defend against this attack is to completely disable your wireless card and run wired. Also, I am an apple user. I find it just amazing at how ignorant a lot of the apple users are acting in how they respond to the exploit. OS X is exploitable as is any other OS. It is not impossible. People who use Macs should almost be flattered that they decided to run this exploit against a mac because it is saying "if this works here, it could work anywhere." That is why the researchers chose to run it against a mac. OS X is a great OS, BUT IT IS NOT PERFECT. Get over it.
