Gshell – A Flexible And Scalable Cross-Plaform Shell Generator Tool

A simple yet flexible cross-platform shell generator tool.

Name: G(Great) Shell

Description: A cross-platform shell generator tool that lets you generate whichever shell you want, in any system you want, giving you full control and automation.

If you find this tool helpful, then please give me a star as it tells me that I should add more features to it.

Is cross-platform, you can use it in operating systems such as:

• Unix-based systems
• GNU/Linux
• Windows
• macOS

Generates the following shells:

• Bind Shells: The target has a listening port and we connect to the target.
• Reverse Shells: We have a listening port and the target connects to us.

Supports the following encodings (as of now):

• URL Encoding: Bypass URL filters
• Base64/32/16 Encodings: Bypass string/keyword filters
• PowerShell Base64 Encoding

Supports the follow IP versions:

Supported protocols:

• TCP
• UDP
• ICMP

Note: You can add your own shells that use other protocols such as DNS.

Supports the following languages and tools:

• PowerShell
• Python
• Bash
• Sh
• Perl
• Socat
• Netcat
• Nc
• Awk
• Lua
• NodeJS
• OpenSSL
• PHP
• Ruby
• Telnet
• Golang
• C#
• Dart
• Groovy
• Many more…

It is limitless, feel free to add as many as you desire!

The shells are stored in markdown files as it makes it easy for everyone.

You can add more bind shells by adding markdown code blocks the following file:

shells/bind_shells.md

You can also add more reverse shells by adding markdown code blocks the following file:

shells/reverse_shells.md

These can be one-liners and multi-liners, it doesn’t matter. You can even add C# multi-liners code blocks if you want.

Example, replace the IP address and the port placeholders or variables values with these placeholders in your code:

$ip, $port

That’s it, now you can add more.

Note: It also offers advice and tips for performing and troubleshooting attacks.
