Windows Vista - First Proof-of-Concept MSH based Virus

These MSH based proof-of-concept viruses depend on whether the Monad shell interface will be ultimately included with Vista.  Most likely the MSH environment will be further secured as Microsoft progresses in the beta testing process.

F-Secure: Danom Virus Description for Variants A thru E -- Describes how each variant interacts with Vista's MSH envrionment

QUOTE: An Austrian virus writer has published five simple viruses targeting Microsoft MSH in a virus writing magazine.  MSH, or Microsoft Command Shell, is a command line interface and scripting language. It's basically a replacement for shells such as CMD.EXE, COMMAND.COM or 4NT.EXE and will ship in 2006. As a command-line front end, MSH resembles many Unix shells quite a bit.

As MSH (codenamed 'Monad') was scheduled to ship as the default shell for Windows Vista (which went to first beta last week), you could argue that these are the first viruses for Windows Vista. However, it has lately been rumoured that MSH might not ship with Vista at all - instead might be part of Microsoft Exchange 2006 or something. We won't know for sure until later.
