Skism

The name of a hacker group that existed from the late 80s through (at least) the middle to late 90s. They worked jointly on an e-zine with Phalcon called 40hex, a newsletter dedicated to the study, dissection, reconstruction and development of Computer Virus programs, and ultimately published Virus Constructor (also known as the VCL MPCG) which would auto-generate the code and binaries for polymorphic virus programs of all known forms (of the time.)
