Uxhalabile okanye ulungelelanisiweyo? Iimfihlo ezisele kwideski yakho

Ndihlala ndifumana imibuzo malunga nokuba kutheni ndine-sticker kwi-ambient light sensors kumakhompyutha am nakwiifowuni. Abanye bacinga ukuba andazi mehluko phakathi kwesensor yokukhanya kunye nekhamera baze bazame ukundichazela ukuba le ayiyikhamera. Abangaqinisekanga kukuba izinzwa zokukhanya ezisemoyeni zingasetyenziswa kunye neendlela zokufunda zomatshini ukukhupha idatha njengoko zilingana neekhamera ezibuthathaka.

Ndihlala ndiva kubantu: “Kodwa asinanto ifihliweyo!” Ewe, unento eninzi yokuyifihla kunokuba ucinga, kwaye idatha yakho ingadityaniswa nedatha enye eqokelelwe kuwe kwenye indawo ukuvelisa ulwazi kwinqanaba ongacinga ukuba kunokwenzeka. Kwaye abo baqokelela idatha abahlali nje kuphela ngabanezizathu ezifanelekileyo. Idatha yakho ingaqokelelwa ngabahlaseli abohlukeneyo ukuze ihlaziywe isetyenziswa yi-AI kwaye isetyenziswe ngeenjongo ezahlukeneyo kunye nezizathu.

Kwikhompyutha yezokhuseleko (cybersecurity), sicinga ukuba ukuba uhlobo lohlaselo lunokwenzeka kwaye kukho ithuba lokwenza uhlaselo, ke khona kunokuba nezizathu zokwenza loohlaselo. Asicingi ukuba abo banokuqokelela idatha bahlala benesizathu esisemthethweni sokuqokelela loo datha. Asicingi ukuba liqela elinye kuphela okanye iqumrhu elixhaphaza ubuthathaka bokuqokelela loo datha.

Apha ngezantsi kukho uluhlu lwezinye izinto ezinokusetyenziselwa ukuhlola kuwe mhlawumbi awuzazi ukuba zinobuchule obunjalo.

Isithethi sakho seTV sinokukuphulaphula

Ndingomnye wabo bahlala bekhetha imodeli yeTV ngaphandle kwemakrofoni okanye ikhamera ngaphambi kokuba ndisuse ngokwasemzimbeni ezo zixhobo. Ndikwanayo ne-firewall yasekhaya kunye nenethiwekhi yangaphakathi ekhuselekileyo, kodwa ndifunde kuyo yonke le minyaka ukuba ndingaxhomekeki kuphela kulawulo olunengqiqo. Nangona kunjalo, ngokusekelwe kwi-WikiLeaks ukukhutshwa kwi 2017 kunye amaxwebhu ukusuka 2014, i-CIA (ngokubambisana ne-MI5) turned speakers in certain TV models into microphones to collect data. Bade baphuhlisa imowudi yokucima inkohliso ukubonisa ukuba umabonwakude ucinyiwe xa beqokelela ezo ngxoxo. Ukuba ucinga ukuba iTV yakho inokuphulaphula incoko yakho, kungcono ukuyikhupha xa ingasetyenziswa. Ikwakonga amandla kuba izixhobo ezifakiweyo nangona zingasetyenziswanga zinokudla umbane.

Ithebhulethi yakho okanye isivamvo sokukhanya kwelaptop sinokubamba isandla sakho okanye umfanekiso wakho

Ndihlala ndihlengahlengisa ukukhanya kwesikrini ngesandla, kwaye ndiyakholelwa ukuba ndinesizathu esivakalayo saloo nto.

Isivamvo sokukhanya esingqongileyo sisetyenziselwa ukulinganisa ubungakanani bokukhanya kunye nokulungelelanisa ukukhanya kwesikrini. Abenzi boluvo bokukhanya okungqongileyo banokusetyenziselwa ukubamba imifanekiso okanye ukubetha izitshixo ukweba iiphasiwedi kunye nedatha. Iqela le Abaphandi be-MIT Kutshanje udale ubungqina bengqiqo ngokusebenzisa izijekulo zesandla zethebhulethi ye-Android ezibanjwe yi-ambient light sensor ukubamba unxibelelwano lokuchukumisa.

Imouse yakho inokuphulaphula incoko yakho

Le iyacaphukisa! Imouse ayinayo imakrofoni okanye isithethi esiza kuguqulwa sibe yimakrofoni ukumamela nantoni na. Nangona kunjalo, kukho uhlaselo lwejelo elisecaleni elaziwa ngokuthi “I-Mic-E-Mouse” eyenza ukuba umhlaseli aphulaphule iincoko zakho ngemouse yakho.

Imouse yokudlala ephezulu (i-DPI ephezulu) inokuxhwilwa yi-sensor yayo ebonakalayo, ke xa uthetha, Ukungcangcazela kwelizwi kunokulinganiswa ngezi sensors. Ukusebenzisa ii-algorithms zokufunda ngomatshini kunye nedatha evela kwii-sensors zemouse, abaphandi bezokhuseleko banokuchonga intetho eqondakalayo evela kwi-vibrations.

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. Nangona kunjalo, 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. Isivamvo sisebenza njengesixhobo esivuthayo, okwenza sibe sempumelelo kwiintshukumo zesebe-lasemacaleni nasekufumaneni ilizwi, njengokuba amaza omsindo anokwenza ukuvuthuza okuncinci.

I-hard disk drive yakho (HDD) umsindo ungabanjwa ukugqiba ulwazi olubalulekileyo

Ngoku xa sesifunde malunga neentshukumo zesebe-lasemacaleni, kunohlobo lwentshukumo olubizwa ngokuba yi DiskFiltration eyakhiwe liqela locwaningi base-Israel eza banakho ukubamba ulwazi olubalulekileyo kumsindo we-hard disk drive esebenza. Uhlobo lwentshukumo olunjalo luphuhlile kwaye luqwalasela izixhobo ezine-air gap. Ngemveliso ezinama air gap, isixhobo asidibani nanoma yintoni inethiwekhi enjenge-intanethi kwaye ngokuqhelekileyo sigcinwa kwiindawo ezibalulekileyo. Izixhobo ezinama air gap azisoze zinganyangekiyo kwiintshukumo ze-cyber. Umzekelo wokwenyani wale mihla yokuhlaselwa yiStuxnet eyayijolise kwiinkqubo zemabini zase-Iran ezenze zonke i-air gapped.

Kolu hlobo lokuhlaselwa, umhlaseli ushukumisa isixhobo ngemalware etshintsha indlela isixhobo esisebenza ngayo. IMalware ingangena kwinkqubo ngumhlaseli okanye ngezinye iindlela. Isixhobo sihlukanisiwe ngemoya, ngoko ke i-malware ayinakuthumela nantoni na ngaphandle. Nangona kunjalo, iyenza isixhobo sisebenze ngandlela thile ukuze ingalo ye-drive ihambe ngeendlela ezithile. Ifowuni ephakathi okanye isixhobo esingahlukaniswanga ngemoya singasetyenziswa ukubamba isandi se-hard disk drive ukusihumusha siphinde sibuyisele idatha ngelixa ibhalwa okanye ifundwa kwi-disk, ifumana ngendlela ephumelelayo umgca womoya.

Ifeni yekhompyutha yakho inokubangela ingozi kwidatha yakho

Unayo i-SSD kwinkqubo yakho kwaye awusebenzisi i-HDD engabizi kwaye enengxolo. Ngoko ke ukuba isixhobo sakho sihlukanisiwe ngemoya, ke idatha ebucayi ayinakuphumla. Ewe! Iqela elinye labaphandi base-Israyeli badala indlela yokuba wena. Nangona i-SSD yakho ingenamandla okujikeleza ukwenza ingxolo njengokuba kwenzeka nge-HDD, ifan yasemakhompyutheni ingasetyenziswa ukuthatha ingxolo ukuphula idatha ebucayi kwiikhompyutheni zakho ezine-air gapped. Kolu hlobo lokuhlaselwa, i-malware kuqala ifaka umonakalo kwisistim ye-air gapped (mhlawumbi ngumphangi kwindawo ekhuselekileyo), okwesibini isantya sefan ekhayeni liya kuguqulwa ngeendlela ezithile. Ingxolo ingadlulisa idatha kwisixhobo esizungezileyo sokuphulaphula.

Izikhululo ze-WiFi zinokubona ngaphezulu kweendonga zakho

Izikhululo ze-WiFi zibuyela ebantwini abagcwele igumbi. Abaphandi banokubona ngokusebenzisa iindonga ukwazi ukuba bangaphi abantu abasegumbini kwaye uchonge abantu ngokuhamba kunye nokuma ngaphandle kokufuna ikhamera.
