Is it Game Over for Windows Vista’s Security?

Reading through my RSS feeds today, I stumbled upon an interesting post over at Neowin entitled “Vista’s Security Rendered Completely Useless by New Exploit” which reports on a new technique that can “bypass all memory protection safeguards that Microsoft built into Windows Vista.”

Mark Dowd of IBM Internet Security Systems (ISS) and Alexander Sotirov, of VMware Inc. have discovered a technique that can be used to bypass all memory protection schemes that have been built into Windows Vista by Microsoft.  These new methods are basically used to get around Vista’s Address Space Layout Randomization (ASLR), Data Execution Prevention (DEP) and other protections by loading malicious content through a web browser.

In a nutshell, this hack is something that many of us weren’t expecting.

While this may seem like any standard security hole, other researchers say that the work is a major breakthrough and there is very little that Microsoft can do to fix the problems. These attacks work differently than other security exploits, as they aren’t based on any new Windows vulnerabilities, but instead take advantage of the way Microsoft chose to guard Vista’s fundamental architecture. According to Dino Dai Zovi, a popular security researcher told, "the genius of this is that it’s completely reusable. They have attacks that let them load chosen content to a chosen location with chosen permissions. That’s completely game over."

Microsoft has yet to post a statement officially, but they are apparently aware of the security issue and are waiting for the exploit to be made public. We can only wait and watch as to what comes up now…

If successful this could be a mess as good as the DNS exploit in the wild these days. This can potentially change the whole view of how the industry thinks about hacks in my opinion. Microsoft will have a quite a lot of work on hands in the coming days, I’m sure. We’ll know more about this in the near future and there even lies possibility of being faced with the prospect of your "secure" server being stripped completely naked of all its protection.

You think its game over for the already struggling Vista?
