dnscat2

dnscat2 is a specialized DNS tunneling tool designed to establish an encrypted command-and-control channel over the DNS protocol, allowing data transmission even through restrictive networks. It operates with a client-server architecture, where the client runs on a compromised machine and communicates with an authoritative DNS server set to forward commands and data. Notably, dnscat2 supports tunneling arbitrary data with built-in encryption, distinguishing it from general-purpose tunneling tools.
