Shaki ama Diyaar? Basaasyaasha miiskaaga saaran

Caadi ahaan waxaan helaa su'aalo ku saabsan sababta aan u leeyahay shaabad ku dheggan dareemayaasha iftiinka ee kumbuyuutarradayda iyo telefoonadayda. Qaar waxay u maleynayaan inaanan kala garanaynin farqiga u dhexeeya dareemaha iftiinka iyo kamaradda oo isku dayaan inay ii sharxaan in tani aysan ahayn kamarad. Wax aanay ogeyn ayaa ah in dareemayaasha iftiinka deegaanka loo isticmaali karo hababka barashada mashiinka si loo soo saaro xog sida ay u yihiin kamarado daciif ah.

Guud ahaan waxaan ka maqlay dadka: “Laakiin waxba ma qarinno!” Haye, waxaad ka qarinaysaa wax ka badan intaad maleyneyso, iyo xogtaada waxaa lagu wada dari karaa xog kale oo laga soo ururiyey meel kale si loo soo saaro sirdoon heer aad maleynin suurtagal ah. Kuwa xogta ururinaya maaha mar walba kuwa leh niyad wanaag. Xogtaada waxaa ururin kara kooxo kala duwan oo khatar ah si loo falanqeeyo iyadoo la adeegsanayo AI loona isticmaalo ujeedooyin iyo ujeedooyin kala duwan.

Amniga internetka, waxaan u maleyneynaa in haddii nooc weerar ah uu suurtagal yahay oo fursad loo helo in weerar la fuliyo, markaas waxaa jiri kara sabab lagu fuliyo weeraradaas. Ma u maleyneyno in kuwa ururin kara xogta ay mar walba leeyihiin sabab sax ah oo ay xogtaas ururinayaan. Sidoo kale ma u maleynayo in hal dhinac ama hay'ad kaliya ay ka faa'iideystaan nuglaansho si ay xogtaas u ururiyaan.

Hoos waxaa ku qoran liiska waxyaabo kale oo loo adeegsan karo si ay kuu basaasaan oo laga yaabo inaadan ogeyn inay leeyihiin awoodahaas.

Afhayeenka TV-gaaga wuu ku dhageysan karaa

I am one of those who usually choose a TV model without a microphone or camera before I need to physically remove those devices. I also have a home firewall and a secured internal network, but I have learned throughout the years not to only rely on logical controls. However, based on a WikiLeaks release in 2017 iyo documents from 2014, the CIA (in cooperation with MI5) turned speakers in certain TV models into microphones to collect data. They even developed a fake off mode to show that the TV is off when they collect those conversations. If you think your TV might listen to your conversation, it is better to unplug it when not in use. It also saves you some energy because plugged devices even while not in use may consume some electricity.

Kaalaalada iftiinka ee kiniinkaaga ama laptop-kaaga waxay qaban karaan gacantaada ama sawirkaaga

Anigu had iyo jeer waxaan si gacanta ah u hagaajiyaa iftiinka shaashadda, wanaaqay in aan sabab wanaagsan u leeyahay arrintaas.

Kaalada iftiinka deegaanka waxaa loo isticmaalaa in lagu cabbiro heerka iftiinka laguna habeeyo dhalaalka shaashadda. Kaaladaha iftiinka deegaanka waxaa loo isticmaali karaa in lagu qabto sawirro ama furayaasha si loo xado erayada sirta ah iyo xogta. Koox ka tirsan cilmi-baarayaasha MIT justi dhawaan waxay abuureen tusaale cadeyn ah iyagoo isticmaalaya iftiinka deegaanka ee kiniin Android ah si ay u qabtaan dhaq-dhaqaaqa taabashada.

Fartaada kombiyuutarka ayaa laga yaabaa inay dhageysato wada sheekeysigaaga

Tan waa mid layaab leh! Farta kombiyuutarka ma laha makarafoon ama xitaa afka hadalka si loogu beddelo makarafoon si ay u dhagaystaan wax kasta. However, waxaa jira weerar dhinac ah oo loo yaqaan “Mic-E-Mouse” taas oo u oggolaanaysa weeraryahanka inuu dhageysto wada sheekaysiiyadaada jiirkaaga.

Mouse ciyaar waxqabad sare leh (DPI sare) waxaa lagu qabsan karaa dareemaha indhaha, marka aad hadasho, gariirka codka waxaa lagu cabbiri karaa dareemayaashan. Iyadoo la adeegsanayo algorithms machine learning iyo xog ka timaadda dareemayaasha jiirka, cilmi-baarayaasha amniga waxay garan karaan hadal la fahmi karo oo ka yimaada gariirka.

Weerarada kanaalada dhinaca waa nooc ka mid ah weerar jireed oo cabbiraya isbeddelka wax soo saarka qalabka inta qalabku sameynayo action. Noocan weerarka badanaa waa mid ka sii horumarsan wuxuuna beegsadaa hanti gaar ah sida furayaasha sirta ah. However, haddii hab weerar loo horumariyo noocyo gaar ah oo qalab ah, ma adkaan doonto in la ballaariyo qalabka kale ee la midka ah oo xitaa si toos ah loo sameeyo.

dareemayaasha dhaqdhaqaaqa (gyroscope) waxaa loo isticmaali karaa in lagu duubo codkaaga

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, making it perfect for side-channel attacks and to capture voice, as sound waves can produce tiny vibrations.

Your hard disk drive (HDD) noise can be captured to steal sensitive data

Now that we’ve learned about side channel attacks, there is a type of attack called DiskFiltration developed by a group of Israeli researchers that can capture sensitive data from the sound of a hard disk drive working. This type of attack is sophisticated and aims at devices with an air gap. Qalabka hawada ka go'an, qalab ma ku xirna shabakad kasta sida internetka waxaana caadi ahaan lagu hayaa goobo xasaasi ah. Qalabka hawada ka go'an ma aha kuwo ka badbaado badan weerarada internetka. Tusaale caadi ah oo weeraradan ah waa Stuxnet oo bartilmaameedsaday nidaamyada nukliyeerka ee Iran kuwaas oo dhammaan hawada ka go'an ahayd.

Noocan weerarka ah, Weeraryahanku wuxuu qalabka ku soo galaa malware bedelaya sida qalabka u shaqeeyo. Malwaren-ka waxaa nidaamka lagu soo galin karaa qof dakhli ah ama habab kale. Qalabka waa hawada ka go'an, markaa malware-ku ma diri karo wax dibadda. However, waxay qalabka ku shaqaysaa qaab gaar ah si gacanta drive-ku ugu dhaqaaqdo qaabab go'an. A nearby smartphone or device that is not air gapped can be used to capture the sound of the hard disk drive to decode it back to data while it is written or read on disk effectively removing the air gap.

Your computer fan can compromise your data

You have an SSD on your system and don’t use a cheap and noisy HDD. So if your device is air gapped, then sensitive data cannot be exfiltrated. Haye! 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. Noocan weerarka ah, malware first infects the air gapped system (perhaps by an intruder to a secured facility), kadib xawaaraha taageerada qaboojinta ayaa lagu beddeli doonaa qaabab gaar ah. Codka ayaa xogta u gudbin kara aalad dhagaysan oo ku dhow.

Calaamadaha WiFi-ga waxay ka arki karaan darbiyadaada

Calaamadaha WiFi-ga waxay ka boodi karaan dadka ku jira qolka. Cilmi-baarayaal waxay arki karaan darbiyada dhex mara si ay u ogaadaan tirada dadka ku jira qolka isla markaana ay u aqoonsadaan shaqsiyaadka iyadoo la raacayo dhaqdhaqaaqa iyo qaabka jidhka iyada oo aan loo baahnayn kamarad.
