Zmist
Computer Virus

Zmist (also known as Z0mbie.Mistfall) is a metamorphic computer virus 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:
This virus supports a unique new technique: code integration.
The Mistfall engine contained in it is capable of
decompiling Portable Executable files to [their] smallest
elements, requiring 32 MB of memory. Zmist will insert
itself into the code: it moves code blocks out of the way,
inserts itself, regenerates code and data references, including
relocation information, and rebuilds the executable.
Variants
Zmist.gen!674CD7362358 - discovered in 2012.
ZMist!IK - discovered 2011 - 2012.
Zmist.A - discovered in 2006 - 2007.

This brief starts where responsible research should: with the source description of “Zmist” as computer Virus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as computer Virus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 15, 2026. The linked authority identifier is Q8073103. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012, 2011, 2006 and 2007.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
