Sality is a File infecting Virus which can append itself to a Host and have the facility to create backdoors to gain unauthorized access to the infected Computers. It can also embed key loggers in the infected Hosts to steal information like user passwords. Furthermore Sality can make the infected Host a bot, using it to attack other hosts or servers.

This new variant gives each infected bot the ability of working as the C&C server removing the centralized dependency of a C&C Server.
