Building Red Team C2 Infrastructure with Havoc

Overview

Havoc is a modern, open-source post-exploitation command and control (C2) framework created by C5pider. 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.

When to Use

Trigger phrases:

"building red team c2 infrastructure with havoc"

Aspect	Recommendation
Domain Age	Register domains 30+ days before engagement
SSL Certificates	Use Let's Encrypt or purchased certificates, never self-signed
Categorization	Submit domain to Bluecoat/Fortiguard for categorization
Sleep/Jitter	Minimum 10s sleep with 30%+ jitter for long-haul operations
User-Agent	Match target organization's common browser user-agent
Kill Date	Set payload expiration to engagement end date
Infrastructure	Separate teamserver, redirector, and phishing infrastructure
Payload Format	Use shellcode with custom loader instead of raw EXE

Technique ID	Name	Phase
T1583.001	Acquire Infrastructure: Domains	Resource Development
T1583.003	Acquire Infrastructure: Virtual Private Server	Resource Development
T1587.001	Develop Capabilities: Malware	Resource Development
T1071.001	Application Layer Protocol: Web Protocols	Command and Control
T1573.002	Encrypted Channel: Asymmetric Cryptography	Command and Control
T1090.002	Proxy: External Proxy	Command and Control
T1105	Ingress Tool Transfer	Command and Control
T1055	Process Injection	Defense Evasion

Rationalization	Reality
"We are too small to be targeted"	Automated attacks target everyone. Size does not matter.
"Security slows us down"	A breach slows you down 100x more. Build security in from the start.
"We will fix it after launch"	Vulnerabilities in production are exploited within hours. Fix before deploy.
