RATAS (Reverse Access Tool Awesome and Secure) is a remote shell with reverse connection and asymmetric encryption. It was written in 2016 for academic purposes, presented as a final degree project of the Higher Degree in Information Systems Administration and Network. The idea was to create something that replicate, but in a way much more basic, the ssh functions.

• Asymmetric encryption
• Reverse connection
• Compatible with ssh

The app is divided in two parts: client and server. From the client you can administer the computer that has installed the server.

You can use any normal command that you be able to introduce in the server shell, and also special built-in commands like READ, START, GETFILE, SENDFILE...

The communication between two processes will be encrypted using asymetric criptography (using RSA-2048 public and private keys to establish the communication and AES-256 onwards). Also have the option to configure known hosts (compatible with the known hosts ssh protocol).

It also include a built-in tool to generate random private and public keys (gen_keys.py).

If you want, you can configure it to use reverse connection in the configuration files.

• Python 2.7
• requests
• pycrypto
