Cloud service cracks VPN passwords in 24 hours
h-online: At the Black Hat hacker conference in Las Vegas, encryption expert Moxie Marlinspike promised that his CloudCracker web service was able to crack any VPN or WiFi connection secured using MS-CHAPv2 within 24 hours. The cost? Around $200. MS-CHAPv2 is based on the eminently crackable encryption algorithm DES. The problem was first documented in 1999 by Bruce Schneier working with two other researchers. A large number of processor cores are still required to crack the encryption within a reasonable time – the number of possible keys makes trying to perform a brute force attack on a normal PC a hopeless task. ...
