    Vista's Security Rendered Completely Useless by New Exploit

    This week at the Black Hat Security Conference two security researchers will discuss their findings which could completely bring Windows Vista to its knees.

    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 safeguards that Microsoft built into Windows Vista. These new methods have been used to get around Vista's Address Space Layout Randomization (ASLR), Data Execution Prevention (DEP) and other protections by loading malicious content through an active web browser. The researchers were able to load whatever content they wanted into any location they wished on a user's machine using a variety of objects, such as Java, ActiveX and even .NET objects. This feat was achieved by taking advantage of the way that Internet Explorer (and other browsers) handle active scripting in the Operating System.

    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, "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."

      This is good news for me. I can charge even more people money for de-virusing their systems. Go Microsoft!
