Zmist (also known as Z0mbie.Mistfall) is a metamorphic computer virus[1] [2] created by the Russian virus writer known as Z0mbie. It was the first virus to use a technique known as "code integration". In the words of Ferrie and Ször:[3]
This virus supports a unique new technique: code integration.The Mistfall engine contained in it is capable ofdecompiling Portable Executable files to [their] smallestelements, requiring 32 MB of memory. Zmist will insertitself into the code: it moves code blocks out of the way,inserts itself, regenerates code and data references, includingrelocation information, and rebuilds the executable.
