Problemi su nastali zbog gre\u0161ke u postavkama DNSSEC za korijensku zonu &#171;DE&#187;, koju provodi organizacija DENIC, odgovorna za domenu prvoga nivoa &#171;DE&#187;. Od 5. svibnja 22:30 do 6. svibnja 1:30 (MSK) poku\u0161aji rezolviranja domena u zoni &#171;DE&#187; putem DNS poslu\u017eitelja koji koriste DNSSEC za provjeru autenti\u010dnosti podataka zavr\u0161avali su gre\u0161kom. Na DNS poslu\u017eiteljima koji koriste DNSSEC, kvarovi su se tako\u0111er primijetili prilikom rezolviranja. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/hr\/domain\/\" title=\"domena\" data-wpil-keyword-link=\"linked\">domena<\/a>, izravno ne koriste\u0107i DNSSEC.     <\/p>\n<p>Problem je pogodio mnoge DNS rezolvore pru\u017eatelja i javne DNS usluge, kao \u0161to su 1.1.1.1 i 8.8.8.8. Kao privremena mjera, tvrtka Cloudflare je u svojoj DNS usluzi 1.1.1.1 onemogu\u0107ila provjeru autenti\u010dnosti putem DNSSEC-a za domene u zoni &#171;DE&#187;. Korisnici DNS rezolvora na kojima je DNSSEC onemogu\u0107en nisu pretrpjeli \u0161tetu.    <\/p>\n<p>Slu\u017ebeno, uzroci incidenta jo\u0161 nisu objavljeni. Pretpostavlja se da je problem nastao zbog gre\u0161ke prilikom a\u017euriranja digitalnog potpisa za zonu &#171;DE&#187;, izvr\u0161enog 5. svibnja u 20:49 (MSK). Klju\u010d koji se koristi za verifikaciju domene prvog nivoa predstavlja korijen povjerenja za ostale klju\u010deve koji se koriste u domenama drugog nivoa, i, zauzvrat, koristi klju\u010d domene &#171;.&#187; kao nadre\u0111eni za potvr\u0111ivanje svog povjerenja.         <\/p>\n<p>Kao rezultat operacije provedene u domeni zone &#171;DE&#187;, kriptografski potpis (RRSIG \u2014 Resource Record Signature) za DNS zapis NSEC3 ispao je neispravan. Zapis NSEC3 se koristi za potvrdu autenti\u010dnosti DNS odgovora o nepostojanju domene, kako bi se isklju\u010dili napadi pomo\u0107u la\u017enih NXDOMAIN odgovora za postoje\u0107e domene. U slu\u010daju problema s digitalnim potpisom za zapis NSEC3, DNS poslu\u017eitelj ne mo\u017ee potvrditi autenti\u010dnost he\u0161ova s podacima o postojanju domena i, shodno tome, ne mo\u017ee provesti provjeru, smatra odgovor la\u017enim i na zahtjeve o bilo kojoj domeni izdaje gre\u0161ku.<br \/>\n<br \/>Izvor: <a rel=\"nofollow\"
