Problems arose due to an error in the DNSSEC configuration for the root zone 'DE', made by DENIC, the organization responsible for the top-level domain 'DE'. From May 5, 22:30 to May 6, 1:30 (MSK), attempts to resolve domains in the 'DE' zone through DNS servers that utilize DNSSEC for data authenticity verification resulted in an error. The failure was also observed on DNS servers implementing DNSSEC during resolution. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/domain\/\" title=\"domains\" data-wpil-keyword-link=\"linked\">domains<\/a>, which do not directly use DNSSEC.     <\/p>\n<p>The issue affected many DNS resolvers of providers and public DNS services, such as 1.1.1.1 and 8.8.8.8. As a temporary measure, Cloudflare disabled DNSSEC authentication for domains in the 'DE' zone in its DNS service 1.1.1.1. Users of DNS resolvers where DNSSEC is disabled were not affected.    <\/p>\n<p>The official reasons for the incident have not yet been announced. It is assumed that the problem arose due to an error during the update of the digital signature for the 'DE' zone, which was carried out on May 5 at 20:49 (MSK). The key used for verifying the top-level domain is the root of trust for the other keys used in second-level domains and, in turn, uses the key for the domain '.' as a higher authority to confirm its trustworthiness.         <\/p>\n<p>As a result of the operation performed in the 'DE' domain zone, the cryptographic signature (RRSIG \u2014 Resource Record Signature) for the DNS record NSEC3 turned out to be invalid. The NSEC3 record is used to authenticate DNS responses about the non-existence of a domain to prevent NXDOMAIN response spoofing attacks for existing domains. In case of issues with the digital signature for the NSEC3 record, the DNS server cannot authenticate the hashes with data about existing domains and, accordingly, cannot perform verification, considers the response fake, and returns an error for any domain queries.<br \/>\n<br \/>Source: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65380\">opennet.ru<\/a>
