A team of researchers from UC Irvine and Tsinghua University has developed a new powerful cache poisoning attack named 'MaginotDNS,' that targets Conditional DNS (CDNS) resolvers and can compromise entire TLDs top-level domains.
The attack is made possible thanks to inconsistencies in implementing security checks in different DNS software and server modes (recursive resolvers and forwarders), leaving roughly one-third of all CDNS servers vulnerable.
