I found this article interesting, take a look and if you will, post your opinions.

"What we're trying to do is force people to use more secure VPN technology in the products they are building," he said.

I think that sums it up pretty well. This is also something for people to take into consideration when they think they are being anonymous on the net. Watch your backs.

Yes indeed

Marlinspike said he developed the service, CloudCracker.com, by taking advantage of a vulnerability he discovered in a widely used virtual private network technology known as point-to-point tunneling protocol

I found this http://www.schneier.com/paper-pptpv2.html

The PPTP protocol is old and has a poorly designed authentication handshake in MS-CHAPv2, he said. "We found we can reduce the security of the protocol to a single DES encryption

CloudCracker's MS-CHAPv2 dictionary represented the entire address space of the Data Encryption Standard (DES), one of the most popular encryption algorithms containing 72,057,594,037,927,936 options.

So i think A flaw in the handshake allows the password to be bruteforced. Advances in computing means it became more feasable and now we have a cloud service to do it in 24 hours at a fair price.
