We released a paper in Virus Bulletin Magazine on the design analysis of Styx exploit pack.
" In this paper, we discuss the details and design of the Styx exploit pack. According to the dictionary, Styx is a river in the underworld, over which Charon ferried the souls of the dead. According to the Styx service provider website, ‘Styx is a river in Greek mythology that formed the boundary between earth and the underworld... It circles the underworld nine times.’ So it seems that the origin of the name is as rigorous as the exploit pack itself."
