Girsh (Golang Interactive Reverse SHell)

Who didn't get bored of manually typing the few lines to upgrade a reverse shell to a full interactive reverse shell (tty spawn, stty size ..., stty raw -echo) or typing the command to use ConPTY.

Description

With Girsh, just run it and it will detect the OS and execute the correct commands to upgrade it to a full interactive reverse shell.

For a Linux:

• Get the terminal's size
• Spawn a tty using python2.7, python3 and python
• Change the terminal as raw

For a Windows:

• Bypass AMSI and use ConPTY to spawn an interactive terminal
• Listen for getting the ConPTY reverse shell

Custom command

sessions: Manage route to socks servers
connect: Manage route to socks servers
menu: Start the reverse shell menu
options: Manage current options (default print them)
start: Start the listener
stop: Stop the listener
restart: Restart the listener
help: help command
