Cavern C2 Blends With Google Apps Script and DNS
TL;DR. A new command and control framework, Cavern C2, leverages DNS tunneling and Google Apps Script to evade detection and blend with legitimate network traffic. - This sophisticated technique hides attacker communications, making it difficult for traditional security measures to identify malicious activity. - The use of Google services adds a layer of legitimacy, allowing C2 traffic to bypass many corporate network security policies. - Organizations must implement advanced behavioral analytics and DNS monitoring to detect such evasive C2 frameworks.
- Cavern C2 is a command and control framework.
- It uses DNS tunneling to exfiltrate data and receive commands.
- Google Apps Script provides a robust and legitimate-looking communication channel for attackers.
- The method makes C2 traffic hard to distinguish from normal network activity.
- Defenders need advanced detection strategies beyond simple signature-based tools.
