Google har rapporteret om en h\u00e6ndelse, hvor angribere har form\u00e5et at f\u00e5 TLS-certifikater til specifikke Google-dom\u00e6ner (for eksempel google.as), online tjenester og store virksomheder i zonerne «.gh», «.sl» og «.as». Angrebet fandt sted gennem kompromittering af registratorer for nationale top-level dom\u00e6ner — «.gh» (Ghana), «.sl» (Sierra Leone) og «.as» (Amerikansk Samoa), hvilket gjorde det muligt at \u00e6ndre DNS-serverne for dom\u00e6ner i disse zoner og omdirigere anmodninger til angribernes servere. Ved at omdirigere trafikken form\u00e5ede angriberne at bekr\u00e6fte ejerskabet af dom\u00e6nerne og f\u00e5 TLS-certifikater, da kontrolanmodninger fra certificeringsmyndighederne efter \u00e6ndringen af oplysningerne i DNS blev sendt til falske v\u00e6rter i stedet for de reelle. <\/p>\n

Uautoriseret modtagelse af certifikater blev opdaget som et resultat af analysen af logfilerne for Certificate Transparency, hvor certifikatmyndighederne registrerer alle udstedte og tilbagekaldte certifikater. Virksomheden Google blokkerede de illegitime certifikater, der blev erhvervet under angrebet, ved hj\u00e6lp af mekanismen CRLSets i Chrome-browseren og opn\u00e5ede ogs\u00e5 tilbagekaldelse af disse certifikater fra certifikatmyndighederne. Det afsl\u00f8res endnu ikke, til hvilke specifikke dom\u00e6ner<\/a> form\u00e5l de falske certifikater blev udstedt, og hvilke virksomheder der blev ramt af angrebet. <\/p>\n

For at minimere risiciene ved gentagelse af s\u00e5danne h\u00e6ndelser anbefales det til dom\u00e6neejerne at organisere l\u00f8bende overv\u00e5gning af offentlige CT-logs (Certificate Transparency) for at opdage uautoriseret udstedelse af certifikater. Det anbefales at tilf\u00f8je CAA (Certification Authority Authorization) DNS-poster, som definerer listen over certifikatudstedere, der har tilladelse til at udstede certifikater for det angivne dom\u00e6ne. Ops\u00e6tning af en CAA DNS-post vil ikke beskytte mod anmodninger om certifikater efter \u00e6ndring af DNS, men efter genopretning af kontrol over DNS kan det forhindre gentagen udstedelse af certifikater af angribere ved at bruge cachede data til ejerskabskontrol.
