METAMORPHIC VIRUSES. "Metamorphics are body-polymorphics." Metamorphic viruses do not have a decryptor or a constant virus body but are able to create new generations that look different. They do not use a data area filled with string constants but have one single-code body that carries data as code." https://lnkd.in/d_2z5qc View in LinkedIn

IMMUNE ESCAPE. "A program can metamorph by translating its own code into a temporary representation, edit the temporary representation of itself, and then write itself back to normal code again. As this process is done on the entire virus the engine also undergoes changes and the whole virus changes with it. The change is made, of course, to attempt to avoid scanners." Not dissimilar to cancer cells. https://lnkd.in/eAcnzhY View in LinkedIn

MORPHING CODE. "Metamorphic viruses do not have a decryptor and do not “unpack” to give a constant virus body like polymorphic viruses do. However, they are able to create new generations of the virus that look different." https://lnkd.in/eXJNZSa View in LinkedIn

STATISTICALLY UNDETECTABLE. "Metamorphic viruses transform their code as they propagate, thus evading detection by static signature-based virus scanners and have the potential to lead to a breed of malicious programs that are virtually undetectable statistically." https://lnkd.in/eXJNZSa View in LinkedIn

WIDELY USED. Self-modifying code (SMC) "broadly refers to any program that loads, generates, or mutates code at runtime. It is widely used in many of the world’s critical software systems to support runtime code generation and optimization, dynamic loading and linking, OS boot loader, just-in-time compilation, binary translation, or dynamic code encryption and obfuscation." https://lnkd.in/dzAS74T View in LinkedIn

SELF-MODIFYING CODE EXISTS. "Q: Can we achieve self-modifying code in high level languages with viruses? Most languages do not allow existing code to be mutated. I am wondering if any viruses can help with that. A: Virus, worms, bad coding practices and even errors in coding surely can do that." https://lnkd.in/egFARnj View in LinkedIn

"SELF-MODIFYING CODE (SMC) is code that alters its own instructions while it is executing. Usually, to reduce the instruction path length and improve performance of simply to reduce otherwise repetitively similar code, thus simplifying maintenance. Thus, SMC is broadly refers to any program that purposely load, generate or mutates code at runtime." https://lnkd.in/dkj4vxW View in LinkedIn

MORPHING FUNCTIONAL CODE. "Metamorphic viruses is well-known with ability to translate, edit and rewrite its own code and it can do serious damage to the system. The main goal of these viruses is to change the appearance but still keeping their functionality." https://lnkd.in/dkj4vxW View in LinkedIn

VIRAL COOPERATION. "More metamorphic engines will be written in the future. Viruses that are able to communicate with each other." https://lnkd.in/d4jm2JB View in LinkedIn

SELF-REPROGRAMMING CODE. "Some viruses rewrite themselves completely each time they infect. These viruses are said to be metamorphic. To put it another way, metamorphic code is code that can reprogram itself." https://lnkd.in/eAcnzhY View in LinkedIn
