I-Paranoid noma ilungisiwe? Izinhloli edeskini lakho

Ngivame ukuthola imibuzo yokuthi kungani nginesitikha kuma-sensors wokukhanya okuzungezile, ama-laptops ami nefoni. Abanye bacabanga ukuthi angazi umehluko phakathi kwenzwa yokukhanya nekhamera futhi bazama ukungichazela ukuthi lokhu akuyona ikhamera. Abangakaze bazi ukuthi izinzwa zokukhanya ezizungezile zingasetshenziswa nezindlela zokufunda ngomshini ukukhipha idatha njengezithombe ezibuthakathaka.

Ngivame ukuva kubantu: “Kodwa asinalutho ukufihla!” Yebo, unokufihla okuningi kunalokho okucabanga, futhi idatha yakho ingahlanganiswa nedatha ehlukene eqoqwe ngawe kwenye indawo ukukhiqiza ulwazi ezingeni ongakwazi ngalo ukucabanga. Futhi labo abaqoqa idatha akudingeki babe nezinhloso ezilungile. Idatha yakho ingaqoqwa ngabantu abahlukahlukene besongela ukuhlaziya usebenzisa i-AI futhi isetshenziselwe izinjongo ezahlukene nezifiso.

Kwezokuphepha ku-inthanethi, sicasula ukuthi uma uhlobo lokuhlasela lungenzeka futhi kukhona ithuba lokwenza ukuhlasela, kungenzeka kube nesizathu sokuzenzela lezo zinhlobo zokuhlasela. Asicabangi ukuthi labo abangakwazi ukuqoqa idatha bahlale benesizathu esisemthethweni sokuqoqa leyo datha. Futhi asicabangi ukuthi iqembu elilodwa noma inhlangano ixhaphaza ubungozi ukuqoqa leyo datha.

Ngezansi uhlu lwezinye izinto ezingasetshenziswa ukukuhlola okungenzeka ukuthi awazi ukuthi zinamakhono anjalo.

Isikhulumi sakho se-TV singakulalela

Ngingomunye walabo abavame ukukhetha imodeli ye-TV ngaphandle kwemakrofoni noma ikhamera ngaphambi kokuthi ngidinge ukususa ngokomzimba lawo madivayisi. Ngiphinde ngibe ne-firewall yasekhaya kanye nenethiwekhi yangaphakathi ephephile, kodwa ngifunde kuyo yonke le minyaka ukuthi ngingathembeli kuphela ezilawulweni ezinengqondo. Kodwa-ke, ngokususelwa ku-WikiLeaks ukukhishwa ku 2017 futhi imibhalo kusuka 2014, i-CIA (ngokubambisana ne-MI5) yaphenduka izipikha kumamodeli athile we-TV zibe yimakrofoni ukuqoqa idatha. Baze bathuthukisa imodi yokucima inkohliso ukukhombisa ukuthi i-TV icishiwe lapho beqoqa lezo zingxoxo. Uma ucabanga ukuthi i-TV yakho ingase ilalele ingxoxo yakho, kungcono ukuyikhipha uma ingasetshenziswa. Iphinde ikusindise amandla ngoba amadivayisi axhunyiwe ngisho nalapho engasetshenziswa angadla ugesi.

Ithebhulethi yakho noma inzwa yokukhanya kwe-laptop ingabamba isandla sakho noma isithombe sakho

Ngihlala ngilungisa ukukhanya kwesikrini ngesandla, futhi ngikholwa ukuthi nginesizathu esihle salokho.

Inzwa yokukhanya ezungezile isetshenziselwa ukukala inani lokukhanya nokulungisa ukukhanya kwesikrini. Izinzwa zokukhanya ezizungezile zingasetshenziselwa ukuthwebula izithombe noma ukucindezela okhiye ukweba amaphasiwedi nedatha. Iqembu le Abacwaningi be-MIT muva nje udale ubufakazi bomqondo ngokusebenzisa izimpawu zesandla sethebhulethi ye-Android ezithathwe yi-sensor yokukhanya ezungezile ukuthwebula ukuxhumana kokuthinta.

Igundane lakho lingalalela ingxoxo yakho

Lokhu kuyahlambalaza! Igundane alinayo imakrofoni noma ngisho nesikhulumi esizoguqulwa sibe imakrofoni ukulalela noma yini. Kodwa-ke, kukhona ukuhlaselwa kwesiteshi esiseceleni esaziwa ngokuthi “I-Mic-E-Mouse” eyenza umhlaseli alalele izingxoxo zakho ngegundane lakho.

Igundane lokudlala eliphezulu (i-DPI ephezulu) ingathunjwa yinzwa yayo ebonakalayo, ngakho-ke uma ukhuluma, ukudlidliza kwezwi kungalinganiswa ngalezi zinzwa. Ukusebenzisa ama-algorithms wokufunda ngomshini kanye nedatha evela ezinzwa zegundane, abacwaningi bezokuphepha bangakwazi ukukhomba inkulumo eqondakalayo kusuka ekudlidlizeni.

Side channel attacks are a type of physical attack that measures changes in device output while a device performs an action. This type of attack is usually more sophisticated and targets certain assets like encryption keys. Kodwa-ke, if an attack method is developed for certain types of devices, it won’t be very difficult to expand it to other similar devices and even automate it.

Motion sensors (gyroscope) can be used to record your voice

Now that we learned your mouse can be used to record your talking, it’s good to know that motion sensors can also be used for the same purpose. This is important as almost all modern smart devices like phones and tablets have a gyroscope or motion sensor. The sensor acts as a vibrating device, ukwenza kube kuphelele ekuhlaselweni kwesiteshi esiseceleni nokubamba izwi, njengoba amagagasi omsindo angakhiqiza ukudlidliza okuncane.

I-hard disk drive yakho (HDD) umsindo ungabanjwa ukweba idatha ebucayi

Manje njengoba sesifunde ngokuhlaselwa kwesiteshi esiseceleni, kukhona uhlobo lokuhlaselwa olubizwa nge- DiskFiltration eyenziwe yiqembu labacwaningi bakwa-Israyeli abangabamba idatha ebucayi kusuka kumsindo we-hard disk drive esebenzayo. Lolu hlobo lokuhlaselwa luyinkimbinkimbi futhi luhlose amadivayisi anegebe lomoya. Ngamadivayisi e-air gapted, idivayisi ayixhunyiwe kunoma iyiphi inethiwekhi efana ne-inthanethi futhi ivame ukugcinwa ezindaweni ezibucayi. Amadivaysi e-Air gapped awavikelekile ekuhlaselweni kwe-cyber. Isibonelo esijwayelekile salokhu kuhlaselwa yi-Stuxnet ebhekiswe ezinhlelweni zenuzi zase-Iran zonke emoyeni.

Kule nhlobo yokuhlasela, umhlaseli ufaka uhlelo olungelona olwejwayelekile kudivayisi olushintsha indlela idivayisi esebenza ngayo. Lolu hlelo oluphazamisayo lungangeniswa ohlelweni ngumhlaseli noma ngezinye izindlela. Idivayisi imiswe ukuthi ingahlangani nenethiwekhi, ngakho-ke uhlelo oluphazamisayo alukwazi ukuthumela lutho ngaphandle. Kodwa-ke, lwenza idivayisi isebenze ngendlela ethile ukuze ingalo ye-drive ihambe ngezinhlaka ezithile. Iselula esiseduze noma enye idivayisi engaxhumekanga enethwekhi ingasetshenziswa ukurekhoda umsindo we-hard disk drive ukuze uyiguqulele emuva kudatha njengoba ibhalwa noma ifundwa ku-disk ngaleyo ndlela isusa umgomo wokungaxhumani nenethiwekhi.

I-fan yekhompyutha yakho ingase iphule ubumfihlo bedatha yakho

Unesistimu ye-SSD ohlelweni lwakho futhi awusebenzisi i-HDD ebiza kancane futhi enomsindo. Ngakho-ke uma idivayisi yakho ingaxhumekile enethwekhi, datha ebucayi ayinakuphuma kuyo. Yebo! Another group of Israeli researchers invented a method for you. Although your SSD doesn’t have an arm to rotate to make noise like with an HDD, your computer fan can be used to capture sound to compromise sensitive data from your air gapped computer. Kule nhlobo yokuhlasela, malware first infects the air gapped system (perhaps by an intruder to a secured facility), then the speed of the cooling fan will be changed in certain patterns. The sound can transmit the data to a nearby listening device.

WiFi signals can see through your walls

WiFi signals bounce off humans in a room. Researchers can see through walls to know how many people are in the room and identify individuals by movement and posture without needing any camera.
