Netcat is the utility knife of networking, so it’s no surprise that shrewd systems administrators remove it from their systems. Such a useful tool would be quite an asset if an attacker managed to find a way in. With it, you can read and write data across the network, meaning you can use it to execute remote commands, pass files back and forth, or even open a remote shell. On more than one occasion, I’ve run into servers that don’t have Netcat installed but do have Python. In these cases, it’s useful to create a simple network client and server that you can use to push files or a listener that gives you command-line access. If you’ve broken in through a web application, it’s definitely worth dropping a Python callback to give you secondary access without having to first burn one of your trojans or backdoors.
