🔍 Network Forensics: DNS Tunneling Analysis
DNS tunneling is a sophisticated technique used by attackers to exfiltrate data and establish covert communication channels by encoding information within DNS queries and responses. This challenge will test your ability to analyze DNS traffic patterns and detect malicious data exfiltration attempts.
🎯 What You'll Learn
- ✓ DNS protocol structure and behavior
- ✓ DNS tunneling detection techniques
- ✓ Network traffic analysis methods
- ✓ Data encoding and exfiltration patterns
🔍 Challenge Overview
You've been provided with DNS query logs from a corporate network. Security analysts suspect that an insider threat has been using DNS tunneling to exfiltrate sensitive data. Your task is to analyze the DNS traffic patterns and extract the hidden information.
