Rhizen Crypt

One in ten newly registered domains is algorithmically generated — tens of thousands each day. Malware, scams and malvertising campaigns use these domains to evade detection and blocking. Today, we are introducing another new security heuristic — Algorithmically Generated Domains. By combining advanced lexical and domain similarity analysis with frontier large language models, we can identify and block random-looking character strings, generated word combinations and numbered families — including names that may look ordinary on their own. This goes far beyond limited lists of known DGA domains and basic entropy checks that attackers can deliberately evade. Block Algorithmically Generated Domains now in the Security tab. Follow @NextDNS for more security releases in the coming days.
