A better netcat-like client for bind and reverse shells

BetterCat - Like a NetCat shell but Better

Description

Have you ever tried to use a netcat shell and thought, "I wish there was a better way"? Well now there is! BetterCat will connect to the shell and do the following:

• Disable saving of the session's history
• Enumerate the operating system, shell and supported terminal interfaces
• Spawn a TTY shell for programs that need them, like sudo
• Integrate the shell with your terminal!
  • You want colour? You got colour! (Yes, it's spelled with a u)
  • You want TAB completion? You got TAB completion!
  • Tired of trying to kill a command with Control-C only for it to kill your shell? No more!
  • Any other default control sequence for your terminal should "Just work"
  • Even vim and emacs work just fine!

Installation

pip3 install -r requirements.txt

Usage

Listening

Instead of nc -lp <port>, use ./BetterCat.py l <port> to listen for incoming reverse shells.

Connecting

Instead of nc <host> <port>, use ./Bettercat.py c <host> <port> to connect to bind shells.

Development

This was hacked together in about 2 days. I'll try to keep working on it, but if you'd like any features or fixes, feel free to ask!

Upcoming features

• Support for more shells, terminals and operating systems
• Better teminal support enumeration
• Support for shells which are already TTYs
• Custom per-shell prompts
• More netcat-like features
• Support for resized terminals
• Methods for spawning a TTY that don't rely on python
• More reconnaisance
• Code cleanup
