The Guns'n'Roses Polymorphic Engine is a newcomer, written by a
person calling himself Slash Wu. Like the Dark Slayer Mutation
Engine, this generator originates from Taiwan - and it only comes
with Chinese documentation.
In the generator's documentation, the author prohibits the use of
the generator in viruses and other malicious software. He claims
to have developed GPE solely for the purpose of protecting data
and programs from unauthorised use. These claims are lent some
credence by the fact that the author has included his apparently
real name and phone number in the introductory notes.
Version 1.00 of the Guns'n'Roses Polymorphic Engine was released
in March 1994. So far, the generator is not known to have been
linked to any virus. It's size is about two kilobytes.
