Why this name?
nc stands for the Netcat command, usually referred as the TCP/IP swiss army. While trying to create a session from a remote target, Netcat is used in the listening mode to double check if an outbound connection can actually exit. If it fails, even more elaborate tools as Meterpreter won't succeed.
Since I typed it so many times during my OSCP exam and in penetration tests, I decided to name my own blog in the same way.
