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:Ferrie, Peter; and Ször, Péter''Zmist opportunities'' Virus Bulletin, March 2001, Abingdon, Oxfordshire (UK), pp. 6–7 This virus supports a unique new technique: code integration. The Mistfall engine contained in it is capable of decompiling Portable Executable files to heirsmallest 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.

Computer Virus
A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a host program. The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. A computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program, but can run independently and actively carry out attacks. Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to initially infect systems and to spread the virus. Viruses use complex anti-detection/stealth strategies to evade antivirus software. Motives for creating viruses can inclu ...

Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Metamorphic Code
Metamorphic code is code that when run outputs a logically equivalent version of its own code under some interpretation. This is similar to a quine, except that a quine's source code is exactly equivalent to its own output. Metamorphic code also usually outputs machine code and not its own source code. Overview Metamorphic code is used by computer viruses to avoid the pattern recognition of anti-virus software. Metamorphic viruses often translate their own binary code into a temporary representation, editing the temporary representation of themselves and then translate the edited form back to machine code again. This procedure is done with the virus itself, and thus also the metamorphic engine itself undergoes changes, which means that no part of the virus stays the same. This differs from polymorphic code, where the polymorphic engine can not rewrite its own code. Metamorphic code is used by some viruses when they are about to infect new files, and the result is that the next ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Z0mbie (virus Writer)
Z (or z) is the 26th and last letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its usual names in English are ''zed'' () and ''zee'' (), with an occasional archaic variant ''izzard'' ()."Z", ''Oxford English Dictionary,'' 2nd edition (1989); ''Merriam-Webster's Third New International Dictionary of the English Language, Unabridged'' (1993); "zee", ''op. cit''. Name and pronunciation In most English-speaking countries, including Australia, Canada, India, Ireland, New Zealand and the United Kingdom, the letter's name is ''zed'' , reflecting its derivation from the Greek ''zeta'' (this dates to Latin, which borrowed Y and Z from Greek), but in American English its name is ''zee'' , analogous to the names for B, C, D, etc., and deriving from a late 17th-century English dialectal form. Another English dialectal form is ''izzard'' . This dates from the mid-18th century and probably derives f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Simile (computer Virus)
Win32/Simile (also known as Etap and MetaPHOR) is a metamorphic computer virus written in assembly language for Microsoft Windows. The virus was released in its most recent version in early March 2002. It was written by the virus writer "Mental Driller". Some of his previous viruses, such as Win95/Drill (which used the TUAREG polymorphic engine), have proved very challenging to detect. When the virus is first executed, it checks the current date. If the host file (the file that is infected with the virus) imports the file User32.dll, then on the 17th of March, June, September, or December, a message is displayed. Depending on the version of the virus, the case of each letter in the text is altered randomly. On 14 May (the anniversary of Israeli independence day), a message saying "Free Palestine!" will be displayed if the system locale is set to Hebrew. The virus then rebuilds itself. This metamorphic process is very complex and accounts for around 90% of the virus' code. After th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of Computer Viruses
The compilation of a unified list of computer viruses is made difficult because of naming. To aid the fight against computer viruses and other types of malicious software, many security advisory organizations and developers of anti-virus software compile and publish lists of viruses. When a new virus appears, the rush begins to identify and understand it as well as develop appropriate counter-measures to stop its propagation. Along the way, a name is attached to the virus. As the developers of anti-virus software compete partly based on how quickly they react to the new threat, they usually study and name the viruses independently. By the time the virus is identified, many names denote the same virus. Another source of ambiguity in names is that sometimes a virus initially identified as a completely new virus is found to be a variation of an earlier known virus, in which cases, it is often renamed. For example, the second variation of the Sobig worm was initially called "Palyh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
