Inkampani yokucubungula inkokhelo ye-VISA, Idayisi ukuthi abathengisi baseNyakatho Melika abasebenza amagalaji kagesi bavezwauchungechunge lokuhlaselwa lamaqembu ezingelekeqe ezifuna i-dphaka i-malware kumatheminali iphuzu lokuthengisa (POS) kumanethiwekhi abo.
Isebenza Kanjani I-Malware Eziteshini Zikagesi
Ezixwayisweni ezimbili zokuphepha ezikhishwe ngoNovemba nangoDisemba, ngokulandelana, iVISA ithe ithimba lalo lezokuphepha langenelela okungenani izehlakalo ezinhlanu ezifana nalezi.
Inkampani ekhipha amakhadi esikweletu ithi amaqembu obugebengu be-cyber ahlasela nge Inhloso eyinhloko yokuthola ukufinyelela kumanethiwekhi wabathengisi kaphethiloli, ukuze faka i-malware kumatheminali wokuthengisa.
I-malware ekhomba ukuthengiswa iyasebenza iskena ngokuqhubekayo i-RAM yekhompyutha ngalokho okubukeka njengedatha yekhadi lokukhokha elingabhalwanga, eliqoqa bese lilayishwa kuseva ekude.
Ithimba le-VISA Payment Fraud Interruption (PFD) ligcina ukuthi amaqembu obugebengu be-cyber kufanele bathole iphuzu elibuthakathaka kuzinqubo zokuqoqa ezisetshenziswa egalaji likaphethiloli.
Yize izindawo eziningi ze-POS zabathengisi abathile zingasekela ukuthengiselana nge-chip, i- Iningi labafundi bamakhadi abafakwe emaphampu egesi abanalo leli khono.
Laba bafundi bekhadi lesikweletu abasetshenziswa iziteshi eziningi zegesi kusasebenza ubuchwepheshe obudala ingafunda kuphela idatha yokukhokha kusuka kumugqa kazibuthe wekhadi.
Imininingwane evela kulaba bafundi bamakhadi abaphelelwe yisikhathi zithunyelwa zingabhalwanga kunethiwekhi enkulu yesiteshi sikaphethiloli. Yilapho izigebengu zithole khona ukuthi zingazinqanda.
NgoNovemba 2019, i-VISA ibike ukuthi ibibhalise ukwephulwa kwezindawo ezimbili zokuhambisa uphethiloli, Kungezwe ezixwayisweni ezintathu ezingezwe ngoDisemba walo nyaka, zigqamisa lokho abakwa-cybercriminals bathole umgomo omusha kanye ne-modus operandi entsha.
Ngokwazi, ukuhlaselwa kwaqala ehlobo lomhlaba osenyakatho futhi okungenani ababili babo kungumsebenzi weqembu labasebenza ngokulandela umthetho abizwa nge-FIN8.
Noma kunjalo, akubonakali njengokwephulwa kwezokuphepha okunzima kakhulu ukuvala.
IVISA ithe indlela elula yezinkampani ezidayisa uphethiloli ukuvikela amakhasimende azo ukubethela kwemininingwane yekhadi ngenkathi idluliswa ngenethiwekhi noma igcinwe kwimemori. Enye inketho shintsha amatheminali amanje ngezinye zesimanje ezingafunda ama-chips wamakhadi.
Kubonakala kungangabazeki ukuthi iyiphi inketho ekhethwayo ye-VISA:
Abathengisi bamafutha kufanele banake lo msebenzi futhi bathumele amadivayisi asekela i-chip lapho kungenzeka khona, ngoba lokhu kuzonciphisa kakhulu amathuba okuhlaselwa.
Futhi lokhu kungaphezu kwesiphakamiso nje.
Abahlinzeki be-Fuel dispenser banazo kuze kube ngu-Okthoba 2020 ukuze phaka abafundi bekhadi elihambisana ne-chip emaphampu abo egesi. Kusukela ngo-Okthoba 2020, i-VISA ihlela ukushintsha umthwalo wanoma yikuphi ukukhwabanisa kwekhadi kusuka kubanikezeli bamakhadi kubathengisi. Akungabazeki ukuthi kuyisikhuthazo esihle kakhulu kuma-opharetha amaningi ukunquma ukuvuselela abafundi babo bekhadi lesikweletu. Kuze kube yileso sikhathi, abaningi bahlala besengozini yokuhlaselwa.
Okwamanje, uma uhlela ukuhamba ngemoto e-United States, ngaphezu kokukhetha iphampu yegesi eholile noma engenayo, kuzofanele uhambe naleyo eza ne-malware noma engenayo.
Futhi, ngoba izigebengu zihlala zithola izindlela ezintsha zokweba idatha yethu, kufanelekile nokuhlola ukusetshenziswa kwethu njalo kuwebhusayithi yethu yekhadi lesikweletu. Ngemuva kwakho konke, njengoba kusho u-Andy Grove omkhulu
Ama-paranoid kuphela asindayo.
