Catch a hacker red handed. NukeNabber will listen on TCP and UDP ports commonly attacked over the internet. A total of 50 ports can be monitored simultaneously. It is designed to give you the information you need in order to trace an attacker including a method of finding an attacker's nickname on IRC (mIRC, VIRC and PIRCH clients are supported).
