30. jaanuaril kell 18:20 (MSK) seisid kasutajad silmitsi ulatusliku hostide tuvastamise rikke t\u00f5ttu .ru domeenitsoonis, mille p\u00f5hjustas viga v\u00f5tmete vahetamisel, mida kasutati domeeni .ru valideerimiseks l\u00e4bi DNSSEC. Selle t\u00f5rke t\u00f5ttu l\u00f5petasid DNS-serverid, mis rakendavad DNSSEC andmete kontrollimiseks, k\u00f5igi .ru domeeni alla kuuluvate domeenide tuvastamise. Probleem m\u00f5jutas vaid neid kasutajaid, kes kasutasid teenusepakkujate v\u00f5i avalikke DNS-teenuseid nagu 8.8.8.8, mis valideerivad p\u00e4ringute \u00f5igusp\u00e4rasust kasutades DNSSEC. DNS-resolverite kasutajad, kus DNSSEC on v\u00e4lja l\u00fclitatud, ei olnud kahjustatud. <\/p>\n

Toimunu meenutab eelmisel aastal juhtunud intsidendi InternetNZ-iga, mis vastutab .NZ domeenitsooni eest ning mis p\u00f5hjustas t\u00f5rke resolvings. domeeninime<\/a> domeenitsoonis .nz KSK-v\u00f5tmete (Key Signing Key) vahetamise t\u00f5ttu, mida kasutatakse DNSKEY kirje digitaalsete allkirjade jaoks, esitades domeenitsooni v\u00f5tmed (ZSK, Zone Signing Key). InternetNZ-i puhul oli viga seotud v\u00f5tmete formaadi muutmisega, kui \u00fclemineku k\u00e4igus uude registri infos\u00fcsteemi. RU domeenitsoonis juhtunu p\u00f5hjused ei ole siiani detailselt v\u00e4lja toodud - RU domeenide koordineerimiskeskus on vaid \u00fcldiselt kinnitanud, et probleem on seotud DNSSEC-i \u00fcmberkonfigureerimisega. <\/p>\n

V\u00e4liselt n\u00e4ib rikkumine toimunud v\u00f5tme vahetamise katse t\u00f5ttu, mida kasutati RU domeeni valideerimiseks. See v\u00f5ti on usaldusv\u00f5rgustiku alus teiste v\u00f5tmete jaoks, mida rakendatakse teise taseme domeenides, ning kasutab omakorda domeeni . kui oma usaldusteabe kinnitamiseks. 26. jaanuaril lisandus RU domeenitsooni DNSEC seadistustes peamise 44301 identifikaatoriga v\u00f5tme k\u00f5rval t\u00e4iendav v\u00f5ti 52263.

Eile, umbes kell 18:20, hakati uut v\u00f5tit kasutama RU tsooni kirjade autentimiseks, kuid p\u00e4rast uuele v\u00f5tmele \u00fcleminekut lakkas autentimine toimimast.

Vana v\u00f5tmega allkiri taastati umbes kell 21:00 (MSK), samas kui esimene \u00f5ige vastus fikseeriti teenuse dnsviz.net poolt kell 22:07 (MSK). Vead p\u00fcsisid ligikaudu kaks ja pool tundi, kuid valeandmete j\u00e4\u00e4kide t\u00f5ttu DNS-serveri vahemikus on t\u00e4ielik taastamine saadaval ainult siis, kui jooksvaid vahemikke ei puhastata. M\u00f5ned teenusepakkujad lahendasid probleemi kiiremini ja radikaalselt, deaktiveerides ajutiselt DNSSEC-i kontrolli oma resolverite seadetes.
