performing-dns-tunneling-detection

What problem does it solve?

Detects covert DNS data channels by analyzing DNS query patterns to reveal tunneling activity, helping security teams surface data exfiltration attempts.

Core Features & Use Cases

• Entropy-based analysis of DNS query names to identify encoded or encrypted data
• Query length distribution checks to flag unusually long subdomains
• TXT record payload inspection to detect data-carrying channels
• Subdomain cardinality analysis to reveal high-volume or dynamic tunneling traffic
• Use Case: Monitor DNS traffic in lab or production environments to surface suspected tunneling for incident response.

Quick Start

Run the agent against a PCAP file to generate a report of DNS tunneling indicators.
