Kokkuv\u00f5tted on tehtud<\/a><\/noindex> Chrome brauseri mitmete kahjulike laiendite blokeerimisest, mille ohvriks on langenud miljonid kasutajad. Esimeses etapis avastas s\u00f5ltumatu uurija Jamila Kaya (Jamila Kaya<\/a><\/noindex>) ja ettev\u00f5te Duo Security Chrome Web Store'i kataloogis 71 kahjulikku laiendit. Kokku olid nendel laienditel \u00fcle 1.7 miljoni installi. P\u00e4rast Google\u2019i teavitamist probleemist tuvastati kataloogis veel 430 sarnast laiendit, mille installide arvu ei avaldatud. <\/p>\n

Rohkem kui 1.7 miljoni installi juures on t\u00e4helepanuv\u00e4\u00e4rne, et \u00fchelgi probleemsetest laienditest ei ole kasutajate \u00fclevaateid, mis t\u00f5statab k\u00fcsimusi, kuidas need laiendite installimised toimusid ja kuidas kahjulik tegevus j\u00e4i m\u00e4rkamatuks. Praegu on k\u00f5ik probleemsed laiendid eemaldatud Chrome Web Store'ist.
\nUurijate arvates on seotud kahjulik tegevus, mis on seotud blokeeritud laienditega, alates jaanuarist 2019, kuid m\u00f5ned domeenid, mida kasutati kahjulike tegevuste teostamiseks, registreeriti juba 2017. aastal. <\/p>\n

Enamasti esitati kahjulikke lisandeid tootmisvahendite ja reklaamiteenuste osana (kasutaja vaatab reklaame ja saab tasu). Lisandites kasutati tehnikat, mis suunab reklaamitavatele saitidele, kui avatakse lehti, mis kuvatakse enne taotletud saidi kuvamist. <\/p>\n

K\u00f5igis lisandites kasutati sarnast tehnikat kahjuliku tegevuse varjamiseks ja Chrome Web Store'i lisandite kontrollimise mehhanismidest m\u00f6\u00f6da hiilimiseks. K\u00f5igi lisandite kood oli praktiliselt identne l\u00e4htekoodide tasemel, v\u00e4lja arvatud funktsioonide nimed, mis olid igas lisandis unikaalsed. Kahjuliku loogika edastamine toimus tsentraliseeritud haldusteenuste serverite kaudu. Alguses \u00fchendas lisand domeeniga, mille nimi oli sama nagu lisandi nimi (n\u00e4iteks Mapstrek.com), seej\u00e4rel suunati see \u00fche haldusteenuse serveri poole, mis edastas j\u00e4rgmiste toimingute skripti.<\/p>\n

T\u00e4ienduste kaudu teostatavate toimingute hulgas mainitakse kasutaja konfidentsiaalsete andmete laadimist v\u00e4lisele serverile, suunamist pahatahtlikele saitidele ja pahatahtlike rakenduste installimise soosimist (n\u00e4iteks kuvatakse teade arvuti nakatumise kohta ja pakutakse pahavara, mis esitatakse viiruset\u00f5rjena v\u00f5i brauseri v\u00e4rskendusena). Suunatud domeenide hulgas on mitmesugused fiskingudomeenid ja saidid, mis n\u00f5uavad uuendamata brausereid, mis sisaldavad parendamata haavatavusi (n\u00e4iteks p\u00e4rast r\u00fcndamist tehti katseid pahavaraga, mis salvestab juurdep\u00e4\u00e4suv\u00f5tmeid ja anal\u00fc\u00fcsib konfidentsiaalsete andmete edastamist l\u00f5ikepaneeli kaudu).<\/p>\n
