New vulnerability discovered for windows vista. This video will show you a way to gain access to windows system without logging into windows vista and without user’s password. I just surprised how it comes. Windows vista is supposed to be secured enough and fully protected with its “cool” UAC. Using any live cd of any Linux distro then you become able to change or rename system files or log on into it without a password. This is what Microsoft offers us. According to the one who discovered the hole, he claims that windows XP aren’t vulnerable to it. It seems that Microsoft doesn’t learn from its old experience or its mistakes. I also get surprised when I compare Aero interface of vista with XGL interface of Linux (watch these: 1, 2).
