Posachedwapa, pa IEEE Symposium on Security and Privacy, gulu la ofufuza ochokera ku Computer Laboratory ya University of Cambridge. za kusatetezeka kwatsopano kwa mafoni am'manja komwe kumalola komanso kulola ogwiritsa ntchito kuyang'aniridwa pa intaneti. Chiwopsezo chomwe chinapezeka chidakhala chosasinthika popanda kulowererapo kwa Apple ndi Google ndipo chidapezeka mumitundu yonse ya iPhone komanso m'mitundu yochepa chabe ya mafoni a m'manja omwe akuyendetsa Android. Mwachitsanzo, imapezeka mumitundu ya Google Pixel 2 ndi 3.
Akatswiri adanenanso za kupezeka kwa chiwopsezo cha Apple mu Ogasiti chaka chatha, ndipo Google idadziwitsidwa mu Disembala. Chiwopsezocho chimatchedwa SensorID ndipo idasankhidwa mwalamulo CVE-2019-8541. Apple idachotsa ngozi yomwe idadziwika ndikutulutsa chigamba cha iOS 12.2 mu Marichi. Ponena za Google, sinayankhebe kuopseza komwe kwadziwika. Komabe, tikubwerezanso kuti ngakhale kuukira kwa SensorID kunkachitika mosavuta pafupifupi mitundu yonse ya mafoni a Apple, mafoni ochepa kwambiri omwe amagwiritsa ntchito Android adapezeka kuti ali pachiwopsezo.
Kodi SensorID ndi chiyani? Kuchokera pa dzina ndizosavuta kumvetsetsa kuti SensorID ndi chizindikiritso chapadera cha masensa. Mtundu wa siginecha ya digito ya chipangizocho, chomwe nthawi zambiri chimafanana ndi foni yamakono ndipo, chifukwa chake, pafupifupi nthawi zonse chimakhala cha munthu wina.
Chifukwa cha khama la ofufuza chitetezo, siginecha yoteroyo anali akonzedwa a mawerengedwe a magnetometer, accelerometer ndi gyroscope masensa (pazifukwa zodziwikiratu, kupanga masensa limodzi ndi kubalalitsa magawo). Deta yoyeserera imalembedwa mu firmware ya chipangizocho ku fakitale, ndipo imakupatsani mwayi wowongolera magwiridwe antchito a mafoni okhala ndi masensa - kukulitsa kulondola kwa malo komanso kuyankha kwa foni yam'manja pamayendedwe. Mukayang'ana tsamba pa intaneti pogwiritsa ntchito msakatuli aliyense kapena poyambitsa pulogalamu, foni yamakono yomwe ili m'manja mwanu nthawi zambiri imakhala yosasunthika. Masamba amawerenga momasuka deta yosinthira kuti agwirizane ndi foni yamakono ndipo izi zimachitika nthawi yomweyo. Chizindikiritsochi chitha kugwiritsidwa ntchito kutsatira munthu yemwe wadziwika kale patsamba lina. Kumene amapita, zomwe amakonda. Njirayi ndiyabwino kwambiri pakutsatsa komwe kumatsata. Ndiponso, kupyolera muzochita zosavuta, chozindikiritsa choterocho chikhoza kugwirizanitsidwa ndi munthu ndi zotsatira zake zonse.
Chiwopsezo chonse cha mafoni a m'manja a Apple pakuwukira kwa SensorID chikufotokozedwa ndikuti pafupifupi ma iPhones onse amatha kugawidwa ngati zida zoyambira, zomwe kupanga, kuphatikiza ma sensor a fakitale, ndi apamwamba kwambiri. Pachifukwa ichi, kusamalitsa uku kunalephera kampani. Ngakhale kukonzanso fakitale sikuchotsa siginecha ya digito ya SensorID. Mafoni a m'manja omwe akuyendetsa Android ndi nkhani ina. Nthawi zambiri, izi ndi zida zotsika mtengo, zosintha za fakitale zomwe sizimatsagana ndi kuwongolera kachipangizo. Zotsatira zake, mafoni ambiri amtundu wa Android alibe siginecha ya digito kuti achite kuwukira kwa SensorID, ngakhale zida zoyambira zimatsimikiziridwa kuti zisonkhanitsidwa ndi mtundu woyenera ndipo zitha kuwukiridwa potengera mawerengedwe a ma calibration.
