Muna Gumiguru 2017, zvakaonekwa zvisingatarisirwi kuti iyo Wi-Fi Yakachengetedzwa Kupinda II (WPA2) protocol ye encrypting yeWi-Fi traffic yaive nenjodzi yakakomba iyo inogona kuburitsa mapassword evashandisi vobva vanzwa kutaurirana kwemunhu akabatwa. Kusagadzikana uku kwakanzi KRACK (pfupi yeKey Reinstallation Attack) uye yakaonekwa nenyanzvi Mathy Vanhoef naEyal Ronen. Mushure mekuwanikwa, kusagadzikana kweKRACK kwakavharwa neyakagadziriswa firmware yemidziyo, uye WPA2 protocol yakatsiva WPA3 gore rapfuura yaifanira kunge yakanganwa zvachose nezvematambudziko ekuchengetedza muWi-Fi network.
Maiwe, idzo nyanzvi dzakawana kusagona kushomeka muWPA3 protocol. Naizvozvo, iwe zvakare unofanirwa kumirira uye kutarisira kune itsva firmware yeasina waya yekuwana mapoinzi uye zvishandiso, zvikasadaro iwe uchafanirwa kurarama neruzivo rwekusagadzikana kweimba uye yeruzhinji Wi-Fi network. Kusagadzikana kunowanikwa muWPA3 kwakaungana kunonzi Dragonblood.
Midzi yedambudziko, sepakutanga, iri mukushanda kwekubatanidza kugadzirisa michina kana, sezvavanodanwa muyero, "kubata maoko". Muchina uyu unodaidzwa kuti Dragonfly muWPA3 standard. Pamberi pekuwanikwa kweDragonblood, yainzi yakachengetedzwa zvakanaka. Pakazara, iyo Dragonblood package inosanganisira shanu kusadzivirirwa: kurambwa kwesevhisi, kaviri kudzikisira kusasimba, uye maviri epadivi-chiteshi kusamira.
Kurambwa kwesevhisi hakutungamiriri mukudonha kwedata, asi chinogona kuve chiitiko chisingafadzi kumushandisi uyo anoramba achitadza kubatana kune yekuwana nzvimbo. Kusagadzikana kwasara kunobvumira anorwisa kuti atorezve mapassword ekubatanidza mushandisi kunzvimbo yekuwana uye kuteedzera chero ruzivo rwakakoshera mushandisi.
Kurwiswa kunodzikisira kuchengetedzeka kwetiweki kunobvumidza iwe kumanikidza shanduko kune yekare vhezheni yeWPA2 protocol kana kune isina kusimba shanduro yeWPA3 encryption algorithms, uye woenderera mberi nekubira uchishandisa nzira dzagara dzichizivikanwa. Side-channel kurwisa inoshandisa maficha eWPA3 algorithms uye kuita kwayo, iyo inozopedzisira yabvumira kushandiswa kweyaimbozivikanwa nzira dzekupwanya password. Verenga zvakawanda pano. Seti yezvishandiso zvekuratidza kusazvibata kweDragonblood inogona kuwanikwa pane iyi link.
Iyo Wi-Fi Alliance, iyo ine basa rekugadzira mazinga eWi-Fi, yakaziviswa nezvekusagadzikana kwakawanikwa. Zvinonzi vagadziri vemidziyo vari kugadzirira yakagadziridzwa firmware kuvhara maburi ekuchengetedza akawanikwa. Pachave pasina chikonzero chekutsiva kana kudzorera michina.
