A Proof of Concept (POC) demonstrating how to expose Mythic (a post-exploitation C2 framework) as an MCP (Multiplayer Command Protocol) server. This allows for interactive command execution in a multiplayer gaming-like environment, blending red team operations with collaborative engagement.
🔗 GitHub Repository: xpn/mythic_mcp
You Should Know:
1. Setting Up Mythic & MCP Server
To deploy this POC, follow these steps:
Prerequisites:
- Docker installed
- Mythic C2 framework set up
- Python 3.x
Steps:
1. Clone the repository:
git clone https://github.com/xpn/mythic_mcp.git cd mythic_mcp
2. Build and run the MCP server:
docker build -t mythic_mcp . docker run -p 5555:5555 mythic_mcp
3. Connect Mythic agents to the MCP server:
python3 mythic_agent.py --server-ip <MCP_SERVER_IP> --port 5555
2. Key Commands for Mythic & MCP Interaction
Mythic C2 Commands:
- List active agents:
mythic list_agents
- Execute a command on an agent:
mythic task_create --command "shell whoami" --agent <AGENT_ID>
MCP Server Commands:
- Check connected clients:
mcp_clients
- Broadcast a command to all agents:
mcp_broadcast "ls -la"
3. Security Considerations
- Isolate the MCP server to prevent unauthorized access.
- Use TLS encryption for MCP communications:
openssl req -new -x509 -keyout server.key -out server.crt -days 365 -nodes
- Monitor MCP logs for suspicious activity:
tail -f /var/log/mcp_server.log
What Undercode Say
This POC demonstrates the creative integration of gaming protocols (MCP) with C2 frameworks (Mythic), enabling collaborative red team operations. However, misuse can lead to severe security risks. Always:
– Restrict MCP server access via firewalls (ufw allow 5555/tcp).
– Audit command logs (grep "exec" /var/log/mcp_server.log).
– Use VPN tunneling for remote connections (wg-quick up wg0).
For defenders, detecting MCP-based C2 involves:
- Network traffic analysis (
tcpdump -i eth0 port 5555). - Endpoint monitoring (
ps aux | grep mythic_agent).
Expected Output:
A functional MCP server linked to Mythic agents, enabling multiplayer-style command execution with logs and security controls in place.
