Podjetje Google je sporo\u010dilo o incidentu, v katerem so napadalci uspeli pridobiti TLS certifikate za posamezne domene Google (na primer, google.as), spletne storitve in velike podjetja na obmo\u010djih '.gh', '.sl' in '.as'. Napad je bil izveden preko kompromitacije registrarjev nacionalnih vrhnjih domen - '.gh' (Gana), '.sl' (Sierra Leone) in '.as' (Ameri\u0161ka Samoa), kar je omogo\u010dilo zamenjavo DNS stre\u017enikov za domene v teh obmo\u010djih in preusmeritev zahtevkov na stre\u017enike zlonamerne programske opreme. S preusmeritvijo prometa so napadalci lahko potrdili lastni\u0161tvo domen in pridobili TLS certifikate, saj so po spremembi podatkov v DNS preverjevalni zahtevki iz overitvenih centrov bili poslani ne na dejanske, temve\u010d na prevarantske gostitelje in obdelani na njih. <\/p>\n

Neovla\u0161\u0107eno dobijanje sertifikata otkriveno je analizom logova Certificate Transparency, u kojima sertifikacioni centri bele\u017ee sve izdate i opozvane sertifikate. Kompanija Google je blokirala dobijene tokom napada nelegitimne sertifikate pomo\u0107u mehanizma CRLSets u pretra\u017eiva\u010du Chrome, kao i uspela da postigne opoziv tih sertifikata od strane sertifikacionih centara. Za sada se ne otkrivaju za koje ta\u010dno domena<\/a> su izdati la\u017eni sertifikati i koje su kompanije pretrpele \u0161tetu od napada. <\/p>\n

Kako bi minimalizovali rizike od ponovnog pojavljivanja sli\u010dnih incidenata, vlasnicima domena preporu\u010duje se da organizuju stalni nadzor javnih logova CT (Certificate Transparency) za otkrivanje neovla\u0161\u0107enog izdavanja sertifikata. U DNS se savetuje dodavanje CAA zapisa (Certification Authority Authorization), koji defini\u0161u listu sertifikacionih centara kojima je dozvoljeno izdavanje sertifikata za navedeni domen. Postavljanje DNS CAA zapisa ne\u0107e za\u0161tititi od zahteva za sertifikat nakon promene DNS-a, ali \u0107e nakon vra\u0107anja kontrole nad DNS-om spre\u010diti ponovno izdavanje sertifikata od strane napada\u010da koriste\u0107i kesirane podatke o vlasni\u0161tvu domena.
