Mu Okutobala 2017, zidadziwika mosayembekezereka kuti protocol ya Wi-Fi Protected Access II (WPA2) yobisa magalimoto a Wi-Fi inali ndi chiwopsezo chachikulu chomwe chimatha kuwulula mawu achinsinsi a ogwiritsa ntchito ndikumvetsera zomwe wozunzidwayo akulankhula. Chiwopsezocho chidatchedwa KRACK (chidule cha Key Reinstallation Attack) ndipo chidadziwika ndi akatswiri Mathy Vanhoef ndi Eyal Ronen. Atapezeka, chiwopsezo cha KRACK chidatsekedwa ndi firmware yokonzedwa pazida, ndipo protocol ya WPA2 yomwe idalowa m'malo mwa WPA3 chaka chatha iyenera kuyiwalatu za zovuta zachitetezo pamanetiweki a Wi-Fi.
Tsoka ilo, akatswiri omwewo adapeza zowopsa zosachepera mu protocol ya WPA3. Chifukwa chake, muyenera kudikiriranso ndikuyembekeza firmware yatsopano yamalo opanda zingwe ndi zida, apo ayi muyenera kukhala ndi chidziwitso chachitetezo chapanyumba ndi pagulu la Wi-Fi. Zofooka zomwe zimapezeka mu WPA3 pamodzi zimatchedwa Dragonblood.
Mizu ya vutoli, monga kale, yagona pakugwiritsa ntchito njira yolumikizira kulumikizana kapena, monga momwe amatchulidwira, "kugwirana chanza". Makinawa amatchedwa Dragonfly mu WPA3 muyezo. Asanatuluke Dragonblood, ankaona kuti otetezedwa bwino. Pazonse, phukusi la Dragonblood limaphatikizapo zofooka zisanu: kukana ntchito, kusatetezeka kuwiri, ndi zovuta ziwiri zam'mbali.
Kukana ntchito sikuyambitsa kutayikira kwa data, koma kungakhale chochitika chosasangalatsa kwa wogwiritsa ntchito yemwe mobwerezabwereza sangathe kulumikizana ndi malo olowera. Ziwopsezo zotsalira zimalola woukira kuti apezenso mawu achinsinsi olumikiza wogwiritsa ndi malo olowera ndikutsata zidziwitso zilizonse zofunika kwa wogwiritsa ntchito.
Kuwukira kwa ma netiweki kumakupatsani mwayi wokakamiza kusintha mtundu wakale wa protocol ya WPA2 kapena kumitundu yocheperako ya WPA3 encryption algorithms, ndiyeno pitilizani kubera pogwiritsa ntchito njira zodziwika kale. Kuwukira kwapambali kumagwiritsira ntchito ma algorithms a WPA3 ndi kukhazikitsidwa kwawo, komwe kumalolanso kugwiritsa ntchito njira zomwe zidadziwika kale zosokoneza mawu achinsinsi. Werengani zambiri apa. Zida zodziwira zovuta za Dragonblood zitha kupezeka pa ulalo uwu.
Wi-Fi Alliance, yomwe ili ndi udindo wokhazikitsa miyezo ya Wi-Fi, idadziwitsidwa za zovuta zomwe zapezeka. Akuti opanga zida akukonzekera firmware yosinthidwa kuti atseke mabowo otetezedwa omwe apezeka. Sipadzakhala chifukwa chosinthira kapena kubwezeretsa zida.
