WPA Crack

So this basically means that someone can't sniff my data but they can get on my network....Correct?

Not exactly. They can see the data that is going TO the PC from the wireless router. They just can't see the data flowing FROM the PC back thru the router to the web host.

Seems like it.

They didn't mention AES at all in the article though.

so they cracked it but it is still more secure then WEP. id still compair WPA-TKIP to a deadbolt on your door and no windows in reach of ground level. someone can get in but they have to work at it.

WPA2-AES is more like a motion sensing machinegun on the roof.

Turbo-charged wireless hacks threaten networks

Graphics cards encryption skulduggery

The latest graphics cards have been used to break Wi-Fi encryption far quicker than was previously possible. Some security consultants are already suggesting the development blows Wi-Fi security out of the water and that corporations ought to apply tighter VPN controls, or abandon wireless networks altogether, in response

Your first example is about cracking WEP which is old news. This article is talking about cracking WPA, so they are not related.

You second example is not really cracking the WPA key, it's just a faster brute force attack.

Let's say I had a computer with two graphics cards, why can't someone come up with a way to use one of the graphics cards ( or some card that could be installed in a slot ) when it is idle or lightly used, to encrypt data ?

Apple is doing something very similar to what you describe, or at least they're making it possible.

Well, I'm not sure if I'd compare it to a deadbolt. I can pick the lock on a standard deadbolt in just a couple minutes using makeshift tools. I'm no locksmith either.

And this WPA cracking isn't quite available to the masses either, unlike WEP cracking.

Unless of course the key is a weak one, in which case it can be brute forced within a reasonable time frame. Good luck brute forcing a WPA key of 63 random characters (I think that's what the max is).

This is the same concept as a Cisco card that is used, an AIM module, which offloads the encryption onto that processor to take away from the main CPU.

Long ago, this is old technology, and can certainly be applied to wireless networks.

If you are that paranoid then simply create a VPN, dial into the VPN over the encrypted wireless access point, and then they would have to break the wireless and the extremely complex encryption with 3DES and other complex technologies long developed.

Geez...

The problem is not encryption it is key management. AES is very secure.

Key management is is the weak point of most privacy schemes. The Enigma machines used by Germany during WWII were quite good. It was the way Germans created the daily key that allowed Alan Turing to crack the codes. If Germans used better keys and prefixed messages with random data (like the Allies did) most likely even the brilliant Turning would have been stymied.

err...thats WEP hacking in 2005. this is WPA cracking, slighty more complex, but still easy to do.
