I-Keylogger Yini?, Ithuluzi noma iSoftware Engalungile

Yini i-Keylogger?

Ukucacisa ukuthi iyi-Keylogger singasho nje ukuthi iyiyo uhlobo lwesoftware noma i-hardwaree esetshenziselwa ukuqopha nokugcina izinkinobho, iyaziwa nangokuthi Ukhiye we-keystroke Futhi le malware igcina yonke into umsebenzisi ayithayiphayo kwikhompyutha noma kwiselula.

Nakuba into evamile iwukuba i-keylogger igcine izinkinobho zokhiye, kukhona nabakwaziyo ukuthatha izithombe-skrini noma ukwenza ukulandela okuzinikele kakhulu. Kunezinhlelo zokusebenza ezimbalwa zokulawula zabazali ezithatha izithombe-skrini, njenge Izingane zeKaspersky Safe, Qustodio y Umndeni wakwa-Norton, lokhu ukubiza ezimbalwa kulokhu okuthunyelwe futhi uma ufuna ukuqapha umsebenzi wezingane zakho ku-inthanethi.

Kuye nge-keylogger, umsebenzi oqoshiwe ungaboniswa kusuka kukhompyutha efanayo noma kwenye, ngaleyo ndlela ulawule konke okwenziwe. Kukhona nezinkampani ezizinikele ekunikezeni lolu hlobo lohlelo olungayilungele ikhompuyutha futhi zikuvumela ukuthi uluhlole ukude kuphaneli yazo yokulawula kunoma iyiphi idivayisi.

Ama-Keylogger ngokuvamile ayi-spyware esetshenziswa ngokusemthethweni ngezinjongo zokuphepha. ukulawula kwabazali noma ukulawula abasebenzi benkampani, nakuba ngeshwa ibuye isetshenziselwe izinjongo zobugebengu. Lezi zinhloso ezingekho emthethweni ziwukuthwebula imininingwane eyimfihlo yabasebenzisi ngaphandle kwemvume noma imvume yabo. Ngokwesibonelo, sebenzisa ukuze ukugebenga umlingani wakho kungaba isiphetho sobugebengu uma ubengazi noma engazange anikeze imvume yakhe yokuthi ufinyelele lolo hlobo lolwazi. Zaziklanyelwe ukuhlala zifihliwe futhi zinganakwa. Yingakho zingavamile ukutholwa, ngoba ngokusebenza aziyingozi kumishini; ayiwunciphisi, ayithathi isikhala esiningi, futhi ayiphazamisi ukusebenza okuvamile kwesistimu yokusebenza.

Lapha ungakwazi ukwazi mahhala futhi izinhlelo ezikhokhelwayo ongazisebenzisa ukuze uthole futhi ususe Keylogger ngaphakathi PC yakho.

Zingaki izinhlobo ze-Keylogger esingazithola?

Kunezinhlobo eziningana zama-keylogger (abaloga bokhiye), ngayinye enezici zayo kanye nezinsiza. Ezinye zezinhlobo ezivame kakhulu zihlanganisa:

1. I-Software Keylogger: Lolu hlobo lwe-keylogger lufakwe kudivayisi futhi lusebenza ngemuva ukuze lurekhode wonke ama-keystrokes. Ingalandwa futhi isebenze kudivayisi efana nohlelo olujwayelekile.
2. hardware keylogger: Lolu hlobo lwe-keylogger luxhumeka ngokoqobo kudivayisi, kungaba ngembobo ye-USB noma ngokuqondile kukhibhodi, ukuze urekhode ama-keystrokes.
3. i-keylogger eyihlane: Lolu hlobo lwe-keylogger lufakwe kudivayisi futhi lulungiselelwe ukuthumela izinkinobho ezirekhodiwe ekhelini le-imeyili elikude noma iseva.
4. spyware keylogger: Lolu hlobo lwe-keylogger lufakwe kudivayisi njengohlobo lwesofthiwe enobungozi, ngenhloso yokweba ulwazi lomuntu siqu noma lwebhizinisi.
5. i-keylogger ye-firmware: Lolu hlobo lwe-keylogger luyi-firmware efakwe kukhibhodi, kungaba nzima kakhulu ukuyibona nokukhipha.

Kubalulekile ukusho ukuthi ukusetshenziswa okungagunyaziwe kwama-keylogger akukho emthethweni emazweni amaningi futhi kungabhekwa njengokuphulwa kobumfihlo, kanye nokusetshenziselwa imisebenzi enonya. Kubalulekile ukuwasebenzisa kuphela ngezinjongo zomthetho kanye nokugunyazwa kwangaphambili.

Ivele nini okokuqala i-Keylogger?

Cishe akukho lutho olwaziwayo ngomlando walo, kukholelwa ukuthi leli thuluzi lakha amaRussia ngesikhathi sempi ebandayo. Abanye bathi yaqale yasetshenziswa ukubamba inkunzi ibhange, inegciwane elaziwa ngeBackdoor Coreflood.

Ngo-2005, usomabhizinisi waseFlorida wamangalela iBank of America ngemuva kokuthi bebe ama- $ 90.000 kwi-akhawunti yakhe yasebhange. Uphenyo lukhombise ukuthi ikhompyutha yalo somabhizinisi itheleleke ngaleli gciwane eselikhulume ngalo, iBackdoor Coreflood. Ngoba wenze ukuthengiselana kwakho kwebhange nge-inthanethi, abenzi be-cybercriminals bathole yonke imininingwane yakho eyimfihlo.

Kungaba yingozi kangakanani?

Konakalise kakhulu, ikakhulukazi uma ungazi ukuthi une-Keylogger efakwe kwikhompyutha yakho. Uma ungazi ukuthi ikhibhodi yekhompyutha yakho iqopha konke okuthayiphayo, ungaveza amaphasiwedi, izinombolo zekhadi lesikweletu, ama-akhawunti asebhange, ngisho nempilo yakho yangasese ingaba sengozini.

Yize kuliqiniso ukuthi kunezinhlelo zalolu hlobo ezisetshenziswa ngokomthetho, lapho isetshenziselwa izinhloso zobugebengu, zithathwa njengohlobo lwe-malware yohlobo lwe-spyware. Lokhu kuye kwavela ngokuhamba kwesikhathi; Akusenomsebenzi wayo oyisisekelo we-keystroke kuphela, kepha futhi kuthatha nezithombe-skrini; ikuvumela ukuthi umise ukuthi imuphi umsebenzisi ozogadwa uma ikhompyutha ineziningi zazo; Igcina uhlu lwazo zonke izinhlelo ezenziwayo, konke ukukopisha nokunamathisela kusuka kubhodi yokunameka, amakhasi ewebhu avakashelwe nosuku nesikhathi, kungalungiswa ukuthumela wonke lawa mafayela nge-imeyili.

Ungayakha kanjani i-Keylogger?

Ukudala i-keylogger kulula kunalokho kubonakala, ungakha elula ngisho nolwazi oluncane lokuhlela. Khumbula ukuthi ungayisebenzisi ngezinhloso ezimbi, njengoba kungenzeka ukuthi wenza ubugebengu obukhulu obungakudalela izinkinga zomthetho, kodwa sesike sakhuluma ngalokhu kwesinye isihloko. siyafundisa ukuze udale i-keylogger yendawo emizuzwini emi-3 ukuhlola le ndlela eyaziwayo yokugebenga. Uma uwuhlobo lwabantu abanelukuluku lokwazi, futhi ufuna ukwanelisa ulwazi lwakho lwezemfundo mayelana nokuphepha kwekhompyutha, hlola isifundo esilandelayo:

Ungayakha kanjani i-Keylogger?

Yini ngempela isitolo se-Keylogger? 

Ukusebenza kwayo kukhuliswe kakhulu, kwaze kwaba sezingeni lokukwazi ukuqopha izingcingo, ukulawula ikhamera nokusebenzisa imakrofoni ephathekayo. Kunezinhlobo ezi-2 ze-Keylogger:

• Ezingeni lesoftware, lokhu kufakwe kudivayisi futhi kuhlukaniswe ngezigaba ezintathu:
  1. IKernel: Ihlala phakathi kwekhompyutha yakho, eyaziwa ngaphansi kwegama le-Kernel, efihliwe ngaphakathi kwesistimu yokusebenza, okwenza kucishe kungenzeki ukutholwa. Ukuthuthukiswa kwabo kuvame ukwenziwa yi-hacker engochwepheshe emkhakheni, ngakho-ke akuvamile kakhulu.
  2. I-API: Kusizakala ngemisebenzi ye-Windows API ukusindisa konke ukucindezela kokhiye okwenziwe ngumsebenzisi kufayela elihlukile. Lawa mafayili ngokuvamile kulula ukuwalulama, njengoba agcinwa kakhulu kunothiphedi.
  3. Umjovo wememori: Lawa ma-Keylogger aguqula amatafula enkumbulo, ngokwenza lolu shintsho uhlelo lungavikela ukulawulwa kwe-akhawunti yeWindows.
• I-keylogger yezinga le-Hardware, abadingi ukufaka noma iyiphi isoftware ohlelweni lokusebenza ukuze isebenze. Lezi izigaba zazo ezingaphansi:
  1. Kususelwa ku-Firmware: I-logger igcina ngokuchofoza ngakunye kukhompyutha, noma kunjalo, i-cybercriminal kumele ikwazi ukufinyelela ikhompyutha ukuthola imininingwane.
  2. Izingxenyekazi zekhompyutha: Ukurekhoda imicimbi, ixhuma nekhibhodi kanye nokunye okufakwayo kukhompyutha. Baziwa ngaphansi kwegama elithi 'KeyGrabber', bazotholakala ngqo ethekwini kungaba i-USB noma i-PS2 yedivayisi yokufaka.
  3. Abasebenzisi bekhibhodi okungenantambo: Zisetshenziselwa igundane namakhibhodi angenantambo, zidlulisa lonke ulwazi oluchofoziwe nolubhalwe phansi; imvamisa yonke le mininingwane ibethelwe, kepha uyakwazi ukuyikhipha.

Ingabe akukho emthethweni ukusebenzisa i-Keylogger?

Ukuze ulawule izingane zakho ku-inthanethi

Ngokuvamile kusemthethweni futhi kusemthethweni ukusebenzisa i-keylogger noma uhlelo lokusebenza lokulawula kwabazali ukuze kuqashwe umsebenzi wezingane zakho kukhompuyutha, inqobo nje uma kunenjongo yokuvikela ukuvikeleka kwazo ku-inthanethi futhi uma kwenzeka zingavuthiwe ngokwanele ukunikeza imvume . Uma sebekhule ngokwanele, kufanele banikeze imvume esobala futhi bazi ukuthi bane-software yokuqapha.

Ngokwesibonelo. ESpain, esimweni sokungabi nemvume yokungena kubumfihlo bomuntu, kungaba semthethweni ukwephula ubumfihlo uma:

• Unamakhodi okufinyelela e-akhawunti yengane yakho ngaphandle kwesidingo sokusebenzisa izindlela zokugebenga.
• Usola ukuthi ingane yakho iyisisulu sobugebengu.

Ukuze ulawule abasebenzi bakho

Kwamanye amazwe kusemthethweni ukusebenzisa a keylogger ukuqapha umsebenzi wabasebenzi yenkampani inqobo nje uma bekwazi. Ezinye zalezi zinhlelo ezithatha izithombe-skrini zabasebenzi yi-Keylogger Spy Monitor, i-Spyrix Keylogger, i-Elite Keylogger, i-Ardamax Keylogger ne-Refog Keylogger.

Ukuba semthethweni kwama-keylogger kungangabazeka futhi kuzoncika ezweni ngalinye, ngakho-ke sikweluleka ukuthi uzazise ngakho.

Sikushiya ukuxhumana okuqondile nencazelo yeSpain neMexico.

I-Boe.es (Spain)

UDof.gob (Mexico)

Ngakolunye uhlangothi, i-Keylogger izohlala ingekho emthethweni uma isetshenziselwa ukwenza ubugebengu njengokuntshontshwa kwamaphasiwedi nolwazi oluyimfihlo.

I-Keylogger ifakwe kanjani emhlabeni wokugebenga?

Abasebenzisi abaningi bathinteka yi-Keylogger ngezindlela ezahlukahlukene, okuvame kakhulu ngokusebenzisa ama-imeyili (ama-imeyili wokweba imininingwane ebucayi) ngento enamathiselwe equkethe usongo. I-Keylogger ingaba khona kudivayisi ye-USB, iwebhusayithi ebucayi, phakathi kwabanye.

Uma uthola "amaholide ajabulisayo" ikhadi likaKhisimusi liziba, "i-trojan" futhi ozokuthola cishe "i-malware ejabulisayo" njengoba izigebengu ze-inthanethi zisebenzisa ithuba lenkathi yamaholide ukusabalalisa amagciwane, ukukhwabanisa nohlelo olungayilungele ikhompuyutha. Ngemva kokuchofoza isixhumanisi noma ukuvula okunamathiselwe, uvumela i-Keylogger ukuthi ifakwe kukhompyutha yakho noma idivayisi yeselula enikeza ukufinyelela kulwazi lwakho oluyimfihlo. Iqiniso liwukuthi kubaduni abanolwazi olunzulu kulolu hlobo lwe I-malware bayakwazi fihla i-keylogger sengathi i-PDF, iZwi ngisho neJPG noma amanye amafomethi asetshenziswa kabanzi. Ngalesi sizathu, siyakugcizelela lokho ungavuli okuqukethwe ongakucelanga.

Kumele kwaziwe ukuthi, uma ikhompyutha yakho ikunethiwekhi eyabiwe, kulula uthole ukufinyelela kuyo futhi uyithelele. Akufanele ufake imininingwane eyimfihlo, ama-akhawunti asebhange namakhadi esikweletu kulolu hlobo lwezinto zokusebenza.

Isabalalisa kanjani iTrojan?

Indlela ejwayeleke kakhulu yokusabalalisa nge-intanethi, basebenzisa amathuluzi amahle kakhulu ukukunxenxa ukuthi ulande igciwane eliyingozi ngezinhloso zabo zobugebengu. Nawa amaTrojans ama-4 ajwayelekile kakhulu:

• Landa amafayela aqhekekile, Ukulandwa kwesoftware okungekho emthethweni kungahle kube nosongo olufihliwe.
• Isoftware yamahhalaSicela ungalandi izinhlelo zokusebenza zamahhala ngaphambi kokuqinisekisa ukuthi iwebhusayithi ithembekile, lokhu okulandwayo kumelela ubungozi obukhulu.
• Ubugebengu bokweba imininingwane ebucayi, Le ndlela ejwayelekile kakhulu yokuhlaselwa kweTrojan ukuthelela amadivayisi ngama-imeyili, abahlaseli bakha izinkampani ezinkulu zezinkampani, bakhuthaza isisulu ukuthi sichofoze kusixhumanisi noma silande izinanyathiselwa.
• Amabhanela asolisayo, unaka kakhulu amabhanela abawanikezayo ukukhushulwa okusolisayo, kungenzeka atheleleke ngaleli gciwane.

Ukugwema ukuba yisisulu salolu hlobo lwegciwane, sincoma ukuthi ufunde isihloko esilandelayo: Ungalikhomba kanjani igciwane lobugebengu bokweba imininingwane ebucayi?

Ngiyisusa kanjani i-Keylogger?

Ama-Keylogger alula, afakwe futhi anikwa amandla yi-API, kulula ukuwasusa. Kodwa-ke, kukhona ezinye ezifakwe njengohlelo olusemthethweni, ngakho-ke uma usebenzisa i-antivirus noma i- i-antimalware cha se bayakwazi ukuthola futhi zinganakwa ngokuphelele, kwesinye isikhathi zize zizifihle njengabashayeli bohlelo lokusebenza.

Ngakho-ke, uma usola ukuthi ubhekwe yi-Keylogger, kungcono kakhulu thola a i-antimalware, azipheli; Uma kwenzeka lokhu kungakusebenzeli, ungakucinga usebenzisa i- Umphathi womsebenzi weWindows. Kufanele ubuyekeze ngokucophelela izinqubo ezisebenzayo eziqukethe i-pc yakho uze uthole noma yiziphi eziyinqaba ongaziboni.
