Tools released at Defcon can crack widely used PPTP encryption in under a day

I wonder how the big VPN service providers are going to react to this, as far as I know ipredator (http://ipredator.se/) uses only MSCAP-2.

Also, why is this news not on the top of "hacker-news", it really puts the usefulness of HN into question if news like these are buried somewhere :-(
