I should mention ncat (coded by the author of nmap), which is a rewrite of netcat. NC can be used for anything and it's so simple and easy to use! Netcat-1.12 -e (ctrl+c terminate cmd.exe)Īmazing program. This is a very powerful tools for network security detection I'd ever used. Use this tool when you need to know for sure what a port is communicating back to you. It retains all of the old functionality and adds several nice features such as group chatting complete with a server. The venerable nc relives as ncat and this is a serious update. and the one i like most is the backdooring capabilities I have seen some people having issues with nc6. Do you guys use it also in IPv6 networks? I know about the v6 version (nc6) but I'm not sure how stable it is in IPv6 cases. I have been using netcat for ages and works great in IPv4 environments. The tool is 'old' and simple, but still is actual and useful. Very cool tool for linux administration & pentesting issues. Thanks to dev it's a very good tool ! Can be used on alls Windows, 7,8,10 :) Mac, Linux does not apply.Long live netcat! One that swiss knife is the best. However, what I wrote above is only for windows. What I did before is to first execute the nc64.exe and then type the command inside the nc64.exe which causes the problem. The thing is, you should just go to the netcat folder and type the command above. Are you sure netcat can be used as a backdoor?

When an attacker successfully compromise a system they need to maintain the connection, that's why the attacker usually installing backdoor on victim computer for future use to make attacker easily connect to victim computer to use victim resource, and collecting data on victim computer. From what I gather, my best chances is at but for some reason (dunno if its just my browser or the site itself) but it keeps timing out. If you run this on a Windows 7 machine, you will get this dreaded message local listen fuxored: INVAL.

But I can not seem to find a windows port of netcat. You can download the windows port of the tool at The command to have netcat listen on a specific port is nc -l PORTNUMBER.

Ive trolled over a bunch of forums and what ever I came across on google.Installing Netcat as a Package tip While beyond the scope of this book, it is important to make sure that your package sources are up to date. For example, to install Netcat from a pre-compiled package on a Debian system, type apt-get install netcat (see Figure 1.2). Option enabled (and generally for good reason).
