Zmist, also known as Z0mbie.Mistfall, is a Windows metamorphic computer virus created by the Russian virus writer Z0mbie and isolated in 2002. It is notable for being the first virus reported to use a code integration technique implemented through its Mistfall engine. According to the provided content, the Mistfall engine can decompile Portable Executable files into very small elements, move code blocks to make room for the virus, insert itself into the host, regenerate code and data references including relocation information, and rebuild the executable after modification. The content states the malware is approximately 9 KB in size and that the Mistfall engine requires 32 MB of memory. Variants mentioned in the content include Zmist.A, ZMist!IK, and Zmist.gen!674CD7362358.
