内容概览

- Investigating suspected DNS tunneling used for C2 communication or data exfiltration - Analyzing DNS query logs for signs of encoded payloads in subdomain strings - Classifying domains as DGA-generated vs. legitimate using statistical or ML methods - Detecting DNS beaconing patterns (regular intervals, consistent query sizes) - Hunting for Iodine, dnscat2, dns2tcp, Cobalt Strike DNS, or Sliver DNS traffic - Monitoring TXT record abuse for command delivery or staged payload download - Building DNS anomaly detection rules for SOC/SIEM deployment Do not use for general DNS performance monitoring or DNS configuration auditing; use DNS health monitoring tools for those. For HTTP/HTTPS-based C2 detection, use network traffic analysis skills focused on web protocols. DISCLAIMER : DNS tunneling tools referenced in this skill (Iodine, dnscat2, dns2tcp) are dual-use. They have legitimate uses (b…
