Yintoni omawuyenze ukuba ufumana ii-imeyile ezikrokrisayo kwi-imeyile yakho

Ukufumana i-imeyile ebonakala ngathi ivela kwidilesi yakho kunokothusa, kodwa kwiimeko ezininzi, ayibonisi ukuba i-akhawunti yakho ifunyenwe. Ngasemva koku kuhlala kukho ubuchule bokulinganisa umthumeli (i-imeyile spoofing) esebenzisa ubuthathaka beprotocol ukwenza umyalezo ubonakale usemthethweni xa ungekho.

Izigebenga ze-Cybercriminal zisebenzisa le ndlela yokunganyaniseki, ukusasaza i-malware, okanye ukweba idatha ngokubhenela ngokukhawuleza, ihlazo, okanye uloyiko lokukufumana ukuba uhlawule nge-cryptocurrency okanye ucofe amakhonkco ayingozi. Imibutho efana ne-INCIBE, i-OCU, kunye neengcaphephe zokhuseleko zilumkisa ukuba ezi imeyile zezenkohliso kwaye icebisa ngokuchasene nokunikezela kwi-blackmail okanye ukunika ulwazi lomntu. Siza kukubonisa ukuba njani. ungenza ntoni xa ufumana ii-imeyile ezikrokrisayo kwi-imeyile yakho.

Yintoni i-imeyile spoofing kwaye kutheni ufumana ii-imeyile ezivela "kuwe"?

I-imeyile spoofing bubuchule obubandakanya ubuxoki umthumeli ngokuguqula izihloko zomyalezo ukuze zibonakale zivela komnye umthombo. Njengoko iingcali ze-cybersecurity zichaza, umhlaseli ulungisa iindawo ezinje ngo "Ukusuka" okanye umgca wesihloko ukuze abonakale njengomntu omthembileyo-nokuba nguwe-ngaphandle kokufikelela kwiakhawunti yakho.

Oku kuyenzeka kuba umthetho olandelwayo we-SMTP, olawula ukuthunyelwa kwe-imeyile, ayifuni kuqinisekisa umthumeli ngokwayo. Ngaloo ndlela, ngezixhobo ezilula okanye ii-API, nabani na unokuseta nayiphi na "Ukusuka:" idilesi abayifunayo; abancedisi bathumela umyalezo, kunye nesihloko esibonakalayo kwibhokisi yakho yangaphakathi ibonisa idilesi umhlaseli angenileyo, nokuba asiyiyo yokwenyani.

Izihloko zobugcisa ze-imeyile (izihloko ezipheleleyo) zityhila indlela yokwenyani yomyalezo, Ekubeni beloga yonke i-hop phakathi kweeseva kwiindawo ezifana ne-Received:, abasebenzisi abaninzi abayijongi le mimandla ngaphambi kokunxibelelana nomxholo.

Ukongeza koku Ukusuka: indawo, abakhohlisi basebenzisa "Phendula-Ku" ukuqondisa kwakhona iimpendulo kwenye iakhawunti abayilawulayo, Ke nokuba i-imeyile ibonakala ngathi ithunyelwe nguwe okanye umfowunelwa, impendulo ifikelela kumhlaseli.

Zisebenza njani obu buqhophololo: ukusuka "kubuqhetseba" bomgunyathi ukuya kwi-sextortion

Enye yeepateni eziqhelekileyo yi-imeyile sextortion: umhlaseli ubanga ukuba wosulele, urekhode, okanye ulawule ikhamera yakho kwaye usongela ukusasaza iividiyo ezisondeleyo ukuba awuhlawuli kwiiyure ze-48, ngesiqhelo kwi-Bitcoin. Le miyalezo ihlala ibango lokuba bebekubeka esweni iiveki okanye basebenzise isoftware "evule imakrofoni yakho."

I-INCIBE icacisa ukuba, kolu hlobo lwephulo, umhlaseli akafikelelanga kwizixhobo zakho okanye neevidiyo zokwenyani, kwaye eyona njongo ikukoyikisa ekufumaneni intlawulo okanye idatha yakho. I-OCU yongeza ukuba ifuna ukusasaza i-malware ngokuncamathisela abosulelekileyo okanye amakhonkco.

Olunye uhlobo lwezilumkiso "zePegasus" zobuxoki okanye enye i-malware "enamandla kakhulu", ngebango lokuba zonke izixhobo zakho zisengozini kwaye intlawulo ekhawulezileyo kuphela eya kuthintela iziphumo ezibi. Ngumzekelo oqhelekileyo wobunjineli bezentlalo esekwe kungxamiseko kunye noloyiko.

Abahlaseli badlala ngehlazo ukuze bakunyanzele; Bahlala befuna i-cryptocurrency kuba kunzima ukuyilandela. Ngamanye amaxesha baquka amagama ayimfihlo avuzwe kukwaphulwa kwedatha ukunika intembeko enkulu, nangona oku akuthethi ukuba banolawulo lokwenyani kwiiakhawunti zakho.

Khangela izibonakaliso eziqhelekileyo: iimfuno zemali eziphuthumayo (ingakumbi kwi-cryptocurrencies), izisongelo zokuthumela umxholo osondeleyo, kunye neeyure ezingama-24-48. Olu xinzelelo luhlala lukhona luphawu oluxhaphakileyo lobuqhetseba kunye nokunganyaniseki.

Khangela izicatshulwa ezibhalwe kakubi, iimpazamo zopelo okanye amabinzana “angaqhelekanga” abonisa ukuzenzekela okanye ukuguqulelwa kakubi, kunye nabathumeli abafihliweyo okanye iidilesi ezingahambelaniyo neziko elisemthethweni.

Zilumkele izicelo zolwazi lomntu siqu okanye lwebhanki nge-imeyile, amakhonkco “wokuqinisekisa iakhawunti yakho,” okanye ukukhuphela isoftware, ngakumbi ukuba umyalezo ubonakala ungaqhelekanga okanye ulinganisa ibhanki yakho, umthengisi, okanye uqhagamshelwano losapho. Hlala uqinisekisa ngokusebenzisa amajelo asemthethweni.
