Preventing Internet Route Hijack with SIDRops Technology

Route hijack attacks cause malicious rerouting of Internet traffic by exploiting the trusting nature of the Internet’s routing system. During the summer of 2025, a route hijack attack affected the Domain Name System’s (DNS) root servers. If it were more widely deployed, technology developed in the IETF’s Secure Inter-Domain Routing Operations (SIDRops) Working Group could have quickly detected and defeated this attack.
