Red Alert! WPA Hacked!

Don’t delay!  Switch to WPA2 today!

For those of you unaware, WPA has been hacked.  As I understand it, it’s not exactly a great hack yet, but a pretty big flaw in TKIP has been uncovered.  It only takes about 12-15 minutes for this hack to work, too, unlike the dictionary attacks that are out there.  By the way, the WPA hack code is already incorporated into a few programs that are widely available on the Internet.  While this hack doesn’t exactly blow your WPA network wide open yet, you should still take notice.  The key word in that last sentence is “YET”.  It’s probably only a matter of time until this hack will make WPA protected networks as easy to hack into as WEP protected networks are today.

Wait a second, you say – What the heck is a TKIP and how did I get one?  TKIP is an acronym for Temporal Key Integrity Protocol.  Think of it as the default encryption mechanism that WPA uses.  WPA can also be configured to use AES, a much stonger technology, instead of TKIP.  Chances are good that if all of your wireless devices support WPA/AES, they also support WPA2.  So, if you are going to change anything at all because of this hack (which I highly recommend), you should simply change to WPA2, which only allows the use of AES.

If you want a very technical discussion on exactly what is currently known about this hack, this article on Ars-Technica goes into great detail.
