Shadow DNS is a router- and DNS-hijacking threat activity cluster associated with selective traffic redirection for online scam operations. The activity is characterized by attackers reprogramming home routers to use attacker-controlled DNS resolvers and employing EDNS0-based evasion to redirect only chosen traffic while reducing the likelihood of detection. This tradecraft indicates a focus on covert manipulation of network infrastructure rather than endpoint malware deployment, enabling spoofing and traffic interception at the DNS layer. Available reporting supports describing Shadow DNS as an intrusion set centered on DNS manipulation and scam enablement, but does not provide high-confidence attribution to a specific country, broader victim geography, or a more extensive alias set.
