HardHat C2
A cross-platform, collaborative, Command & Control framework written in C#, designed for red teaming and ease of use
HardHat is a multi-user C# .NET-based command and control (C2) framework designed to aid in red team engagements and penetration testing. It aims to improve quality-of-life during engagements by providing a robust, easy-to-use C2 framework.
HardHat has three main components:
- An ASP.NET teamserver
- A Blazor .NET client
- Built-in C# based implants
- Support for 3rd party implants in other languages
Full documentation is available at https://docs.hardhat-c2.net/.
NOTE: HardHat is in an Alpha release; it will have bugs, missing features, and unexpected things will happen. Thank you for trying it, and please report back any issues or missing features so they can be addressed.

Getting Started
Installation
Docker
- Install Docker and Docker Compose
- Run
docker compose up -d- Optionally, provide
HARDHAT_ADMIN_USERNAMEand/orHARDHAT_ADMIN_PASSWORDas environment variables; if omitted, the default admin username and randomly generated password will be written to the teamserver logs on first run
- Optionally, provide
- Navigate to https://localhost:7096/ in your browser
Manual
- Install .NET 7 SDK from Microsoft
- Run
dotnet runfrom the.\TeamServerdirectory to build and start the teamserver - Run
dotnet run https://<TEAMSERVER_HOST>:<TEAMSERVER_PORT>from theHardHatC2Clientdirectory- For example, assuming your teamserver is running on the same host and default port:
dotnet run https://127.0.0.1:5000
- For example, assuming your teamserver is running on the same host and default port:
- Navigate to https://localhost:7096/ in your browser
To configure the teamserver's listening address (i.e., where clients will connect), edit .\TeamServer\Properties\LaunchSettings.json and change "applicationUrl": "https://127.0.0.1:5000" to the desired location and port.
Setup
- Login to the client web UI using the username and password set with environment variable or printed to STDOUT by the teamserver
- Navigate to the Settings page and create a new user account
- If successful, a message will appear; you may then login with that account to access the full client
