Netcat is a simple Unix utility which reads and writes data across network connections, using TCP or UDP protocol. It is designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts.  At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities. Netcat, or "nc" as the actual program is named, should have been supplied long ago as another one of those cryptic but standard Unix tools.

Excerpt from manual:

Inappropriate Usage : ncat should never be installed with special privileges (e.g. suid root).. That would open up a major security vulnerability as other users on the system (or attackers) could use it for privilege escalation.

Note: in this release, the -e option is not disabled. In other words, please be careful with this powerful tool.
