BOPing is a network scanner for the infamous Back Orifice program. It is many times faster than the ping sweeper built in to the original client program.
This is intended as a vigilante tool to notify victims who unknowingly have the trojan on their system. It includes the ability to notify detected victims by sending them a BO messagebox message directly from within the program.
This is first and foremost a simple tool for network administrators to perform a quick scan of their local area networks. Do not attempt to use this program against computers on the Internet that you have no right to scan since you are highly likely to be tracked down and attract the attention of your ISP and have your account terminated.
