A metamorphic virus is a kind of malware that can change its own code and signature patterns with every iteration. The authors of metamorphic viruses apply such techniques as to disguise the malicious code in a way it won’t get detected by antivirus and antimalware programs. Additionally it is done to create the attribution of the malware more difficult. Metamorphic viruses are regarded as the more advanced cyber
threat than typical malware or for example the polymorphic virus. But even though it constantly changes its code the function of the virus remains the same. The longer the malware stays in a computer or device the more iterations it does. With every time each iteration gets increasingly complicated. The virus completely rewrites its code with every propagation and this makes it nearly impossible for any antivirus
solution to detect, quarantine or eliminate the threat. With every propagated distribution the virus automatically does a record of itself thus removing any type of signature traditionally looked for by systems. The metamorphic virus uses different code transformation techniques including:
How Does Metamorphic Virus WorkThis kind of malware takes the virus mutation to another level. The virus has Pine Tree State to change each VDR ( virus secret writing routine) and subsequently EVB ( encrypted virus body). The Pine Tree State does the disassemblement of the code and represents it with a meta language that shows how the code performs but doesn’t not take into consideration how the code archives its performance. As a result a new code on the Pine Tree State tip appears to have no similarity to its original syntax. But the functionality is equivalent. The Examples Of Metamorphic VirusThe most notable examples of metamorphic viruses will include:
How To Detect Metamorphic VirusOf course, metamorphic viruses are much more difficult to detect but this doesn’t necessarily mean they are completely undetectable. To prevent the infection users should implement the following steps against the threat:
How To Know If I Have Metamorphic VirusTo deal with the problem successfully first you need to acknowledge that you have it. In case of a computer virus the sooner you do this the better. NOTE: Computer network security, information security, individual computer security – all these parts of cybersecurity are very large and necessary for understanding whether you use a computer for your activities. Here’s the general signs that you might actually have the metamorphic virus on your computer and that might mean you need to do something as soon as possible to prevent further damage to your cybersecurity wellbeing:
How To Prevent Metamorphic Virus InfectionNow the best solution would be to avoid the infection in the first place. The old saying goes “It’s better to prevent the problem than deal with it“. Read the several tips on how to stay away from the metamorphic virus and not to endanger yourself with it:
Which virus changes itself each time it is installed?A polymorphic virus is a harmful, destructive or intrusive type of malware that can change or "morph," making it difficult to detect with antimalware programs.
Which virus changes its code every time it replicates?Explanation. The polymorphic virus evades detection by changing its virus signature each time it infects a new file.
Which malware type can change code and signature pattern with each iteration?Metamorphic malware are self-modifying programs which apply semantic preserving transformations to their own code in order to foil detection systems based on signature matching.
What is polymorphic and metamorphic virus?A polymorphic virus, sometimes referred to as a metamorphic virus, is a type of malware that is programmed to repeatedly mutate its appearance or signature files through new decryption routines.
