DNSFS works by splitting files into small chunks (roughly 180 bytes) and storing them as base64-encoded strings within . Users can "upload" files to open DNS resolvers and retrieve them later using specific hostname queries, effectively treating the DNS cache as a temporary storage medium. IETF RFC 6763 (DNS-SD)

This research focuses on detecting botnets that use DNS TXT records for command and control (C&C) or data exfiltration, a mechanism very similar to how DNSFS operates. Access: Available via ResearchGate . RFC 6763 (DNS-based Service Discovery) dnsf.txt

The official standard for structuring DNS records (specifically PTR, SRV, and TXT) to facilitate service discovery across networks. Access: IETF RFC 6763 . Key Concept of DNSFS DNSFS works by splitting files into small chunks
