What C2 Communication Analysis does

C2 Communication Analysis examines malware command-and-control traffic over HTTP, HTTPS, DNS, and custom protocols to identify beaconing patterns, decode message structure, map infrastructure, and attribute threat actors.

C2 Communication Analysis is cataloged under Data on DirSkills. C2 Communication Analysis comes from a repository tagged ai-agents, claude-code, cloud-security, cybersecurity and devsecops.

Documentation

README

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.

Prerequisites

This is the opening of the README. Read the full README on GitHub.
