Possible Future Improvements
With its capabilities, Dust is reminiscent of basic Win32 viruses from the pioneering days. In the future, we'll surely meet other Win32 techniques, such as entry point obscuring (EPO), PE file merging, polymorphic prologs, metamorphism, and more. These are beyond the scope of this article; if you're interested, take a look at the 29A Labs web site and the VX Heavens site.
Further, more specific WinCE techniques can be expected, such as memory residency; and, with that, connected on-the-fly infection, stealth, sending SMS and dialing numbers (on SmartPhones), and so on.
