Amagciwane Polymorphic - kuyini nendlela yokubhekana nazo?

Sonke wezwa ngezingozi isofthiwe enonya, ikakhulukazi inethiwekhi. Esimisweni esikhethekile ukuvikelwa ezinsongweni ehlukahlukene kukhona imali ebhekile, kodwa ingabe ikhona umuzwa kulezi izindleko? Cabangela izinhlobo ezivamile ukutheleleka kwezokuxhumana, ikakhulukazi eyingozi kakhulu kubo - amagciwane polymorphic.

Okwakushiwo ukutheleleka

Ngu Isifaniso ngomuthi, tangcondvomshini kubhekwe njengento ehlukile "eziphilayo" ukuthi bayakwazi sithathe "ukutheleleka" phakathi nokuxhumana imvelo digital: kusuka ku-intanethi noma ngokusebenzisa abezindaba esikhiphekayo engahloliwe. Yingakho igama lalowo iningi izinhlelo ezinonya - amagciwane. Ekuqaleni ukubonakala kwakhe amagciwane polymorphic babe fun for ochwepheshe, into kokuhlolwa yamakhono awo, kanye ukuhlolwa kwezimiso ezithile ukuvikelwa computer nakunethiwekhi imithombo. Manje kubaduni kusukela Ukumnaka wathutha obala imisebenti yebugebengu, nabo bonke ngenxa kwembulunga yonke ka izinhlelo yasebhange digital ukuthi ukunikeza ukufinyelela e-wallets kusukela cishe noma kuphi emhlabeni. Ulwazi ngokwayo, okuyiwona manje yokuzingela igciwane abalobi, manje ifinyeleleka kakhulu, libe lakhuphuka lafika ku amashumi namakhulu izikhathi kuqhathaniswa bezikhathi zangaphambi digital.

Incazelo nomlando nesenzakalo

amagciwane Polymorphic, njengoba leli gama lisikisela, bayakwazi ukushintsha ikhodi yabo uma udala ikhophi yakho. Ngakho, Nzalo igciwane ayikwazi kuchazwe ejenti elwa namagciwane oyedwa imaski futhi wathola wonke ngoba iluphu elula. Igciwane kuqala ukushintsha siqu ikhodi ubuchwepheshe yayo wadedelwa emuva ngo-1990 ngaphansi kwegama lonwabu. ukuthuthukiswa ezibucayi igciwane lokubhala ubuchwepheshe kwaba kamuva lapho kufika polymorphic ikhodi ugesi, enye yazo ibizwa ngokuthi Trident Polymorphic Engine kwakusakazwa nge imiyalelo enemininingwane e yokugcina umlando BBS. Nge kwesikhathi polymorphism ubuchwepheshe buye zabhekana yiziphi izinguquko ezinkulu, kodwa zikhona ezinye izindlela ukufihla izenzo ezinonya.

ukusabalala amagciwane

Ngaphezu ethandwa phakathi angadingeki bese igciwane abalobi-e-mail izinhlelo, amagciwane asabekayo angangena ikhompyutha yakho kanye amafayela alandiwe, usebenzisa elinegciwane izinsiza i-Inthanethi nge- iisxhumanisi. Ukuze ukutheleleka zingasebenzisa okuphindiwe elinegciwane amasayithi adumile. abezindaba esikhiphekayo, ngokuvamile isula umsebenzi, futhi, kungaba yimbangela ukutheleleka, njengoba kungenzeka iqukethe amafayela onegciwane ukuthi umsebenzisi uyakwazi ukusebenzisa uqobo. izicelo abahlukahlukene Izifaki ukukhubaza anti-virus software okwesikhashana kufanele kube uphawu umsebenzisi, okungenani ukuhlolwa ngokujulile amafayela elisebenzisekayo. ukusatshalaliswa Automatic amagciwane kungenzeka uma ukuthola yalezi zitha nemiphumela ethile engathandeki Ukuvikelwa izinhlelo implementations enjalo isofthiwe ngokuvamile okuhloswe ngazo izinhlobo ezithile amanethiwekhi kanye namasistimu asebenzayo. Popularization software ehhovisi futhi uye yabakhanga abahlaseli, kuphumele amamakhro ekhethekile elinegciwane. Lezi zinhlelo igciwane ube ethile sina, basuke "ohlanganiswe" ukuba uhlobo lwefayela, vumelekile amagciwane kusuka Igama-ifayela Akakwazi ukuhlanganyela i isipredishithi Excel.

izinhlobo polymorphism

isakhiwo Polymorphic selihlukene e yinkimbinkimbi algorithm olusetshenziswa amaqembu amaningana. Oligomorfnye - silula - ukusebenzisa njalo ukubethela ikhodi yakho siqu, ngakho ngisho antivirus ukukhanya uyakwazi ukubala futhi iwukudambisa kubo. Lokhu kulandelwa amakhodi iziqondiso nje ezimbalwa for ukubethela ukusetshenziswa ikhodi "ezingenalutho", ukuthola isimiso esinjalo samagciwane kufanele ukwazi zivundulula iqembu udoti.

Amagciwane isicelo ukushintsha isakhiwo ayo ngaphandle ukulahlekelwa ukusebenza, kanye nezinye amasu cryptographic eqaphela eliphansi, kakade ukumela kuyinselele engathí sina ukuthola namagciwane. Ezingelapheki amagciwane polymorphic, ehlanganisa amabhlogo isofthiwe Ungafaka ingxenye ikhodi ezindaweni ezahlukene ifayela elinegciwane. Eqinisweni, le virus akudingekile ukusebenzisa ikhodi "ezingenalutho", elisetshenziswa njengesibonakaliso ikhodi elisebenzisekayo amafayela onegciwane. Ngenhlanhla abasebenzisi anti-virus Onjiniyela software ngokubhala la magciwane kudinga ulwazi ezibucayi assembler futhi itholakala kuphela program ezingeni eliphezulu kakhulu.

Izifiso, izimpokophelo Umgomo we operation

Ikhodi okunobuthi njengengxenye isibungu inethiwekhi kungaba usongo olukhulu, ngoba, ngaphezu velocity esiphelweni, inikeza idatha emiphumeleni elimazayo futhi ukungcoliswa amafayela system. Shona-virus polymorph lichaza ekwakheni izibungu noma ngesisekelo ikhodi yabo kwenza kube lula yokuwuthola izici zokuphepha kukhompyutha yakho. e amagciwane imigomo zingase zihluke kakhulu, kusukela ukweba elula futhi ukubhujiswa okuphelele kwalelizwe idatha aqoshiwe kwi unomphela kwisitoreji semidiya, kanye ukuphazamiseka wokusebenza futhi destabilization yabo ephelele. Ezinye izinhlelo igciwane uyakwati kudlulisela ukulawula abahlaseli computer ukuvula noma icuphe kufihlwe nezinye iprog Ramm, ukuxhuma kunethiwekhi izinsiza noma ikhokhwe ukudlulisa ifayela lula. Abanye bayakwazi komzamo "baphile" kumemori futhi ukulawula inqubo yamanje kwezicelo egijima ucinge amafayela ezifanele ukuthelela noma ukudala ukuphazamisa umsebenzisi.

izindlela yokuvikela

Ukufaka anti-virus kumelwe for iyiphi ikhompuyutha exhunywe kwi inethiwekhi, njengoba uhlelo lokusebenza awukwazi ukuzivikela wena kwi-malware, kodwa elula kakhulu. I Ukuvuselela esifike yolwazi kanye ukuskena esihleliwe amafayela, ngaphezu unomphela uhlelo lokuqapha, izosiza ukuba aqaphele ukutheleleka nekugwema umthombo. Lapho usebenzisa i-computer amadala noma okulengayo namuhla kungaba lula ukufaka isofthiwe unqulo wesi arab kuphela esebenzisa isitoreji ifu semininingwane igciwane. Ukukhethwa kwezinhlelo ezinjalo ubanzi kakhulu, futhi konke ngempumelelo ntshashintshe nge intengo anti-virus software akuyona ukhuluma ngokuthembeka kwakhe okusezingeni eliphezulu ngaso sonke isikhathi. A plus ocacile izinhlelo ezikhokhelwayo - khona esebenzayo ukwesekwa kwamakhasimende kanye izibuyekezo njalo igciwane yolwazi, Nokho, isikhathi analogue nazo ephendula ukuvela igciwane amasignisha amasha e inethiwekhi.
