Ghost Shell is a lightweight and fast remote shell that provides secure communication between a client and a server. The communication channel is encrypted using the Noise_NNpsk0_25519_AESGCM_SHA256 noise protocol and derives the pre-shared key using SHA256.
The noise protocol provides a framework for building encrypted channels, and Ghost Shell uses it to secure communication between the client and server. The pre-shared key is derived using the SHA256 hash function, ensuring secure key exchange. The encryption algorithm, AES-GCM, provides authenticated encryption with additional data (AEAD), which ensures data integrity, authenticity, and confidentiality. These measures provide end-to-end security, protecting against eavesdropping, tampering, and forgery of messages.
Rust (1.48 or later)
Building and Running
To build the project, run the following command:
git clone https://github.com/unclesp1d3r/ghost_shell.git cd ghost_shell cargo build --release
To run the server, use the following command and pass in the password as the first argument:
To run the client, use the following command and pass in the password as the first argument:
Once connected to the server, the client can send shell commands to the server, and the server will execute the command and return the output to the client. The client can also exit the connection by sending the exit command.
Ghost Shell currently supports the following commands:
echo: Echoes back the input provided as an argument.
exec: Executes a command on the server and returns the output.
exit: Exits the remote shell and terminates the connection.
Additional commands may be added in the future.
Ghost Shell uses the Noise_NNpsk0_25519_AESGCM_SHA256 noise protocol to encrypt the communication channel between the client and the server. This protocol provides end-to-end security, protecting against eavesdropping, tampering, and forgery of messages.
The Noise_NNpsk0_25519_AESGCM_SHA256 protocol utilizes Elliptic-curve Diffie-Hellman key agreement with Curve25519, a strong and efficient key exchange mechanism. The pre-shared key is derived using the SHA256 hash function, ensuring secure key exchange. The encryption algorithm, AES-GCM, provides authenticated encryption with additional data (AEAD), which ensures data integrity, authenticity, and confidentiality.
While we have taken steps to ensure the security of the communication channel, it is important to note that no security solution is foolproof. Therefore, Ghost Shell may be vulnerable to attacks such as brute-force password cracking or implementation-specific attacks.
Furthermore, Ghost Shell is a work in progress and has not been audited in any way. Therefore, we do not recommend using it in a production environment without first conducting a thorough security review.
