### Context
The identification of DNS tunneling activity signifies an attempt by the attackers to maintain a covert communication channel with the compromised systems.

### Findings
- **Tunneling Details**: Encoded DNS queries and responses are used to bypass traditional network monitoring.
- **Infrastructure**: Analysis shows multiple subdomains dynamically resolving to various IP addresses, indicating a sophisticated command and control (C2) setup.

### Recommendations
- Deploy DNS monitoring solutions to identify and block tunneling activities.
- Implement strict outbound DNS policies to prevent unauthorized queries.
