Morphine is a polymorphic, delphi open source PE Crypter which was developed by a coder of a Windows NT Rootkit called Hacker Defender.
In computer terminology, polymorphic code is code that uses a polymorphic engine to mutate while keeping the original algorithm intact. That is, the code changes itself each time it runs, but the function of the code (its semantics) will not change at all.
