Iikhomputha ze-imeyili ziyaziwa nangokuthi 'i-spoof' i-imeyile, okuthetha 'ukunyaniseka'. Yilapho umthumeli ngokuzenzekelayo utshintsha iinqununu ze-imeyile ukuba zijonge njengokuba zibhalwe ngumnye umntu. Ngokuqhelekileyo, igama lomthumeli / idilesi kunye nomzimba womyalezo ufomathiweyo ukuba avele kumthombo osemthethweni, njengokungathi i-imeyili ivela kwibhankini okanye iphephandaba okanye inkampani esemthethweni kwiWebhu. Ngamanye amaxesha, i-spoofer iya kwenza i-imeyile ibonakale ivela kummi wabucala kwenye indawo.
Kwiimeko ezininzi ezinobungozi zee-imeyile, le miyalezo isetshenziselwa ukusasaza iinkolelo zasezidolophini kunye namabali ahamba phambili (umzekelo, uMel Gibson wayetshiswa ngokutshatyalaliswa njengomntwana osemtsha; Kwezinye iimeko ezixhatshazayo, i-imeyli ene-spoofed inxalenye yesohlwayo (ukudibanisa umntu). Kwezinye iimeko, i-imeyile ekhutshiwe isetyenziselwa ukuthengisa ngokungekho mthethweni inkonzo enokuthengiswa okanye ukuthengisa umkhiqizo onobuqhetseba njenge- scareware .
Yintoni i-imeyli ye-Hoax / Spoofed View?
Nantsi imimiselo ye-imeyli yokuphangisa ephihliweyo ukuba ibonakale imthethweni .
Kutheni Umntu Okhohlakeleyo & # 39; Spoof & # 39; i-imeyile?
Iikhomputha ze-imeyile zenzelwe ngokukodwa iinjongo ezinobungcali.
Injongo yoku-1: i-spoofer ye-imeyile izama uku "phish" amagama akho asepayili kunye namagama angena ngemvume
I-Phishing yilapho umthumeli ongathembeki ethemba ukukukhohlisa ekuthembeleni i-imeyile. Iwebhusayithi yekhohlisi (iphoswe) iya kulinda kwicala, ngokucokisekileyo ukuguqulwa ukubonakala ngathi iwebhusayithi yebhanki esemthethweni kwi-intanethi okanye inkonzo ye-Web ehlawulwe, njenge-eBay. Kude kakhulu, amaxhoba aya kukholelwa i-imeyli ene-spoofed ngokungazi kwaye unqakraza kwiwebhusayithi yobuxoki. Ukuthembela kwiwebhsayithi ephosiweyo, ixhoba liya kufaka iphasiwedi kwaye ingene ngemvume, ukuba yifumane umyalezo wephutha lobuxoki othi "iwebhusayithi ayifumaneki". Ngethuba le nto, i-spoofer engathembeki iya kuthatha ulwazi oluyimfihlo yecala, kwaye iqhubeke nokurhoxisa imali yexhoba okanye yenza intsebenzo engathembekiyo yokufumana imali.
Injongo yesi-2: i-spoofer ye-imeyili ngu-spammer ezama ukufihla ubungqina bakhe bokwenyani, ngelixa egcwalisa ibhokisi lakho leposi ngeentengiso.
Ukusebenzisa isofthiwe yokuthumela i- massware ebizwa ngokuthi "i- ratware ", i-spammers izakuguqula idilesi ye-imeyile ukuba ibonakale njengommi ongenatyala, okanye njengenkampani esemthethweni okanye iqumrhu likarhulumente. Injongo, njenge-phishing, kukuba abantu bathemba i-imeyile ngokwaneleyo ukuze bayivule kwaye bafunde ukukhangisa kogaxekile ngaphakathi.
I-imeyile ifakwe njani ngeSpoofed?
Abasebenzisi abangathembekanga baya kutshintshana amacandelo ahlukeneyo e-imeyile ukuze badibanise umthumeli njengomnye umntu. Imizekelo yeepropati ezikhutshwayo:
- KWIgama / idilesi
- UKUFUNDA-Igama / idilesi
- I-RETURN-PATH idilesi
- I-IP ye-SOURCE idilesi okanye "i-X-ORIGIN" idilesi
Ezi zakhiwo ezintathu zokuqala zingatshintsha ngokulula ngokusebenzisa izicwangciso kwi-Microsoft Outlook, Gmail, Hotmail, okanye enye i-software ye-imeyile. Ipropati yesine ngasentla, idilesi ye-IP, inokuguqulwa, kodwa ngokuqhelekileyo idinga ulwazi oluninzi olusetyenzisiweyo lokwenza idilesi ye-IP ekhohlisayo.
Ngaba i-imeyile ifakelwe ngesandla okanye ngeekhompyutha?
Nangona ii-imeyile ezitshintshiweyo zichithwa ngesandla, uninzi lwee-imeyile ezikhutshiwe zidalwe yi-software ekhethekileyo. Ukusetyenziswa kwee-mass-mailing "i- ratware " iinkqubo zixhaphake phakathi kogaxekile. Iiprogram ze-Ratware ziza kusebenza ngezinye iilwimi zamagama ezizakhelekileyo ukuze zenze iithayibhile ze-imeyile ezijoliswe kuyo, zikhuphe i-imeyile ye-source, ize ikhuphe i-imeyile ye-spoof kulezo thagethi. Ngamanye amaxesha, iinkqubo ze-ratware ziza kuthatha uluhlu olungenalo mthethweni lweedilesi zee-imeyile, kwaye ke zithumele ugaxekile ngokufanelekileyo.
Ngaphandle kweeprogram ze-ratware, iimpompo zamathume-mvume nazo zininzi
Iifom zizinto zokuziphendulela ezizenzayo njengoluhlobo lwegciwane. Kanye kwikhompyutheni yakho, i-worm-mail worm iya kufunda idilesi yakho yeedilesi. Emva koko i-worm-mailing worm izakuphazamisa umyalezo ophumayo oza kubonakala uthumela evela kwigama lakho ledilesi, kwaye uqhubeke uthumela lo myalezo kubo bonke uluhlu lwabahlobo. Oku akugcini nje ukucaphukisa amaninzi wabamkeli, kodwa uyangcolisa idumela lomngane wakho ongenacala. Ezinye ziyazi kakuhle iimpompo zokuthumela i-mass-size ziquka: Sober , Klez , kunye ne-ILOVEYOU.
Ndiyazi njani kwaye ndikhusela njani ii-imeyile?
Njengawe nawuphi na umdlalo womdlalo ebomini, ukukhusela kwakho okulungileyo kukungathembeki. Ukuba awukholelwa ukuba i-imeyile iyinyaniso, okanye ukuba umthumeli uvumelekile, ke ungakhange ucofe kwikhonkco uze uthayiphe idilesi yakho ye-imeyile. Ukuba kukho ifayile yokunamathisela, musa ukuyivula, hleze iqulethe inkokhelo yokuhlawula igciwane. Ukuba i-imeyile ibonakala ingcono kakhulu ukuba yinyani, mhlawumbi kunjalo, kwaye ukungaqiniseki kwakho kuyakusindisa ekuchazeni ulwazi lwakho lwebhanki.
Nayi imimiselo emininzi yeenkcukacha ze-phishing ne-spoof ze-imeyili. Zijonge wena, kwaye uqeqeshe iso lakho ukuba ungathembeli ezi ntlobo zee-imeyile.
