Excerpt

Analyzing DNS Logs for Exfiltration

When to Use

Use this skill when:

SOC teams suspect data exfiltration through DNS tunneling to bypass firewall/proxy controls
Threat intelligence indicates adversaries using DNS-based C2 channels (e.g., Cobalt Strike DNS beacon)
UEBA detects anomalous DNS query volumes from specific hosts
Malware analysis reveals DNS-over-HTTPS (DoH) or DNS tunneling capabilities

Do not use for standard DNS troubleshooting or availability monitoring — this skill focuses on security-relevant DNS abuse detection.
