In computer terminology, '''polymorphic code''' is code that mutates while keeping the original [[algorithm]] intact.

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

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