Girsh v0.41 releases: Automatically spawn a reverse shell fully interactive

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:

• Download ConPTY on the same machine and same port as the reverse shell server
• Listen for getting the ConPTY reverse shell
