+# VM Infrastructure Setup Guide
+
+**Mission:** Mission 3 - Ghost in the Machine
+**Purpose:** Docker-based vulnerable VM network for technical challenges
+**Network:** 192.168.100.0/24
+**Date Created:** 2025-12-27
+
+---
+
+## Overview
+
+Mission 3 requires a vulnerable virtual machine network for players to practice network reconnaissance, banner grabbing, and service exploitation. This guide documents the Docker container setup for the training network used by Zero Day Syndicate.
+
+**Architecture:** Docker Compose multi-container setup
+**Network Isolation:** Internal Docker network (192.168.100.0/24)
+**Security:** Containers are isolated from host network, intentionally vulnerable services contained

+
+### 2. distcc Service (Vulnerable)
+
+**Purpose:** Exploitation target demonstrating remote code execution

+
+**Exploitation Flow:**
+1. Player scans network: `nmap -sV 192.168.100.0/24`
+2. Discovers distcc on port 3632
+3. Exploits using Metasploit or manual command injection
+4. Gains access to `/var/log/zeroday/sales_log.txt`
+5. Submits flag: `flag{distcc_legacy_compromised}`
+6. Operational logs appear in game, triggering M2 revelation
+
+**CVE-2004-2687 Explanation:**
+distcc allows arbitrary command execution due to insufficient input validation. Attackers can execute shell commands on the server by sending specially crafted requests.

+2. Browses to `/pricing/data.txt`
+3. Recognizes Base64 encoding
+4. Uses CyberChef workstation to decode
+5. Submits flag: `flag{pricing_intel_decoded}`
+
+---
+
+## Setup Instructions
+
+### Prerequisites
+- Docker Engine 20.10+
+- Docker Compose 1.29+
+- 2GB available RAM
+- Network isolation from production environment
+
+### Installation Steps
+
+1. **Create project directory:**
+```bash
+mkdir -p m03_ghost_vm_network
+cd m03_ghost_vm_network
+```
+
+2. **Create directory structure:**
+```bash
+mkdir -p ftp-data distcc http-data/pricing
+```
+
+3. **Copy configuration files:**
+- Save `docker-compose.yml` to project root
+- Save `proftpd.conf` to project root
+- Save `distcc/Dockerfile` to `distcc/` directory
+- Save `distcc/operational_logs.txt` to `distcc/` directory
+- Save HTML/text files to appropriate `http-data/` directories
+
+4. **Build and start containers:**
+```bash
+docker-compose up -d
+```
+
+5. **Verify network:**
+```bash
+docker-compose ps
+docker network inspect m03_ghost_vm_network_zeroday_network
+```
+
+6. **Test connectivity from player VM terminal:**
+```bash
+# From game's VM terminal interface
+nmap -sV 192.168.100.0/24
+nc 192.168.100.10 21
+curl http://192.168.100.30/pricing/data.txt
+```
+
+### Teardown
+
+```bash
+docker-compose down
+docker network prune
+```
+
+---
+
+## Integration with Game
+
+### VM Terminal Access
+
+The game's VM terminal should have network access to the Docker bridge network. This can be achieved through:
+
+**Option 1: Docker Network Sharing**
+- Game VM container joins `zeroday_network`
+- Direct IP access to 192.168.100.x hosts
+
+**Option 2: Port Forwarding**
+- Expose container ports to host
+- Game VM accesses via localhost:port
+- Less realistic but simpler setup
+
+**Recommended:** Option 1 for realistic network topology
+
+### Flag Validation
+
+**Flag Submission Flow:**
+1. Player completes VM challenge (nmap, netcat, exploitation)
+2. Terminal displays flag (e.g., `flag{ftp_intel_gathered}`)
+3. Player submits flag at drop-site terminal
+4. Game validates flag against objectives.json
+5. Ink script `m03_terminal_dropsite.ink` triggers narrative response
+6. distcc flag specifically triggers M2 revelation event
+
+**Flag List:**
+- `flag{network_scan_complete}` - nmap scan completed
+- `flag{ftp_intel_gathered}` - FTP banner captured
+- `flag{pricing_intel_decoded}` - HTTP Base64 pricing decoded
+- `flag{distcc_legacy_compromised}` - distcc exploitation successful (triggers M2 revelation)
+
+---
+
+## Security Considerations
+
+### Isolation
+
+**CRITICAL:** This network contains intentionally vulnerable services.
+
+- ✅ Docker network isolated from host network
+- ✅ Containers do NOT expose ports to 0.0.0.0 (host machine)
+- ✅ No outbound internet access from vulnerable containers
+- ✅ User permissions minimized (non-root where possible)
+
+### Firewall Rules
+
+If deploying in cloud/production environment:
+
+```bash
+# Block external access to vulnerable services
+iptables -A INPUT -p tcp --dport 21 -j DROP
+iptables -A INPUT -p tcp --dport 3632 -j DROP
+iptables -A INPUT -p tcp --dport 80 -j DROP
+
+# Allow only from game server subnet
+iptables -I INPUT -p tcp -s <GAME_SERVER_IP> --dport 21 -j ACCEPT
+iptables -I INPUT -p tcp -s <GAME_SERVER_IP> --dport 3632 -j ACCEPT
+iptables -I INPUT -p tcp -s <GAME_SERVER_IP> --dport 80 -j ACCEPT
+```
+
+### Monitoring
+
+Monitor container logs for unexpected activity:
+
+```bash
+docker-compose logs -f
+```
+
+Set up alerts for:
+- Unexpected external connections
+- Resource exhaustion
+- Container restart loops
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+**Issue:** Containers can't communicate
+- **Solution:** Verify Docker network: `docker network inspect m03_ghost_vm_network_zeroday_network`
+- Check IP assignments match `docker-compose.yml`
+
+**Issue:** FTP banner not appearing
+- **Solution:** Check ProFTPD config syntax: `docker exec m03_ftp_server proftpd -t`
+- Restart container: `docker-compose restart ftp-server`
+
+**Issue:** distcc exploitation failing
+- **Solution:** Verify distcc version 2.18.3 installed
+- Check logs: `docker logs m03_distcc_server`
+- Ensure `--allow 0.0.0.0/0` flag present
+
+**Issue:** Player VM can't reach Docker network
+- **Solution:** Add player VM to Docker network:
+  ```bash
+  docker network connect zeroday_network <player_vm_container>
+  ```
+
+---
+
+## Testing Checklist
+
+Before deployment, verify:
+
+- [ ] All containers start successfully
+- [ ] IP addresses assigned correctly (192.168.100.10, .20, .30)
+- [ ] FTP banner shows "ProFTPD 1.3.5" when connecting via netcat
+- [ ] HTTP server serves Base64 encoded pricing data
+- [ ] distcc service responds on port 3632
+- [ ] Operational logs accessible after distcc exploitation
+- [ ] Network isolated from external internet
+- [ ] Firewall rules configured (if production environment)
+- [ ] Flag validation works in game
+- [ ] M2 revelation event triggers after distcc flag
+
+---
+
+## Maintenance
+
+### Updates
+
+**DO NOT** update vulnerable service versions:
+- ProFTPD must remain 1.3.5
+- distcc must remain 2.18.3
+- Apache can be updated (no known vulnerabilities used)
+
+### Backups
+
+Configuration files to version control:
+- `docker-compose.yml`
+- `proftpd.conf`
+- `distcc/Dockerfile`
+- `distcc/operational_logs.txt`
+- All `http-data/` content
+
+Data volumes (if persistent data needed):
+- `ftp-data/` directory
+

+
+## Educational Notes
+
+### Learning Objectives Supported
+
+This VM network enables players to:
+
+1. **Network Reconnaissance**
+   - Use nmap for service discovery
+   - Understand CIDR notation (/24)
+   - Identify open ports and service versions
+
+2. **Banner Grabbing**
+   - Use netcat for manual service enumeration
+   - Understand information disclosure via banners
+   - Correlate version information with CVE databases
+
+3. **Service Exploitation**
+   - Understand CVE-2004-2687 (distcc RCE)
+   - Practice responsible exploit usage (isolated environment)
+   - Connect technical exploitation to narrative impact
+
+4. **Intelligence Correlation**
+   - Combine digital evidence (logs) with physical evidence (from rooms)
+   - Understand how attackers monetize vulnerabilities
+   - Recognize attack attribution patterns
+
+### Real-World Parallels
+
+- **Zero Day Markets:** Underground exploit marketplaces exist (Zerodium, etc.)
+- **Sector Premiums:** Real exploits command higher prices for critical sectors
+- **Healthcare Attacks:** Ransomware targeting hospitals is a real threat (see: Change Healthcare 2024)
