Microsoft recently invited hackers and "security professionals" at the Black Hat convention in Las Vegas to "test" Vistas security measures. Even giving out beta releases of Vista to attendees.

It didn't take long for one researcher to bypass Vistas security.

" Joanna Rutkowska, a Polish researcher at Singapore-based Coseinc, showed that it is possible to bypass security measures in Vista that should prevent unsigned code from running.

And in a second part of her talk, Rutkowska explained how it is possible to use virtualization technology to make malicious code undetectable, in the same way a rootkit does. She code-named this malicious software Blue Pill. "

Microsoft says they are working on a system to prevent these types of attacks in the final version of Vista. While Vista still is a way off, I really hope Microsoft will get it together.
