SiphonDNS Tool Demonstrates Covert DNS Data Exfiltration Techniques
/ 1 min read
🌀 New techniques for covert data exfiltration using DNS unveiled. A recent article discusses innovative methods for hiding data traffic within DNS queries to evade traditional detection systems. The author introduces a proof of concept tool, SiphonDNS, which demonstrates various techniques for data exfiltration without relying on subdomains, thus reducing the likelihood of detection. Key methods include using EDNS extensions to transmit larger data chunks and leveraging DNS query structures to obscure information. While these techniques can enhance stealth, they may compromise performance and are still susceptible to monitoring if not tailored to specific environments. The article emphasizes the importance of adapting these methods to avoid detection while exploring the evolving landscape of DNS protocols.
