In computer science (or more often, in computer underground terms) '''polymorphic code''' is code that mutates while keeping the original [[algorithm]] intact.

Polymorphic code was invented in 1992 by the [[security cracking|cracker]] [[Dark Avenger]] (a [[pseudonym]]) as a mean to avoid pattern recognition from antivirus-software.

This is sometimes used by [[computer virus]]es, [[shellcode]]s and [[computer worm]]s to hide their presence.
