In 1993 the virus group Phalcon/Skism from Canada published a
polymorphic engine called Dark Angel's Multiple Encryptor or DAME. The
generator's name may have been meant as a dig at some members of the
anti-virus community, who had been using the name DAME for Dark
Avenger's Mutation Engine, MtE.
Dark Angel published his generator during the summer of 1993 in issue 11
of Phalcon/SKISM's magazine, 40Hex. Dark Angel has also written the two
virus creation toolkits published by Phalcon/SKISM, the PS-MPC and G2.
DAME was distributed as commented source code. Along with the generator,
Dark Angel published an article which dealt with polymorphism and the
writing of polymorphic generators in general.
Dark Angel was apparently not completely satisfied with his initial
product, because he introduced an improved version of DAME in the next
issue of 40Hex.
The first version of DAME, 0.90, took up 1574 bytes. The improved 0.91
version had grown to 1960 bytes. Dame is known to have been linked to
several different viruses.
