analyzing-command-and-control-communication
Analyzes malware C2 communication over HTTP, HTTPS, DNS, and custom protocols to reverse-engineer beacon patterns, command structures, data encoding, and infrastructure (primary servers, fallback domains, dead drops). Use after reverse engineering reveals network traffic needing protocol analysis or when building detection signatures for a framework like Cobalt Strike, Metasploit, or Sliver.

# Analyzing Command-and-Control Communication
## When to Use
- Reverse engineering a malware sample has revealed network communication that needs protocol analysis
- Building network-level detection signatures for a specific C2 framework (Cobalt Strike, Metasploit, Sliver)
- Mapping C2 infrastructure including primary servers, fallback domains, and dead drops
- Analyzing encrypted or encoded C2 traffic to understand the command set and data format
- Attributing malware to a threat actor based on C2 infrastructure patterns and tooling
**Do not use** for general network anomaly detection; this is specifically for understanding known or suspected C2 protocols from malware analysis.
