Zvakakuita kuti uore mwoyo uchingofunga nezvazvo, handizvo here? 5x3823
Zvino chimbofungidzira uchipfuura nemamiriro ezvinhu aya. Humwe usiku, pashure pezuva refu rebasa, Rafael Pereira, mutori wemifananidzo ane makore 34 okukura, akasarudza kuti yakanga yava nguva yokumira ndokupfuuridzira zvaakanga achiita zuva raitevera. Pakati pehusiku, komputa yake, iyo yakaramba yakabatika, yakaita ruzha rwakakanganisa.
Sezvineiwo, Rafael akaenda kunotarisa kuti chii uye paakaona kuti yaive meseji kubva kuMicrosoft yaibvunza kuwana kuita basa, yakafunga kuti yaive update uye yakati ok. Nenguva isipi, skrini diki MS-DOS (Microsoft Disk Inoshanda Sisitimu) akaisa chimwe chinhu chaasina kuona uye hapana chimwe chakaitika.
Rafael akabva achengeta basa rake, akadzima kombiyuta ndokuenda kunorara murunyararo, achifunga kuti aizomuka nerimwe zuva. Zvisinei, paakamuka ndokudzokera patafura yake, akawana mafaira ose padesktop yake aine a icon yepepa risina chinhu uye iyo mazita anoshamisa.
Pandakaedza kuvhura rimwe remafaira aya, Windows haina kuratidza chirongwa uye pakabva paonekwa hwindo riine meseji yaikumbira kubhadhara mukati. bitcoin kudzima mafaira. Ndakatadza zvachose kuwana chero zvinyorwa paPC - ndaingokwanisa kuwana mafaera enotepad.

Mushure mekurwiswa, Rafael akakumbira rubatsiro kubva kushamwari dzinoshanda muIT, dzakamukurudzira kuti atsvage mapurogiramu anobvisa mafaira mushure mekurwiswa kwecyber. ransomware, asi haana kuwana aizomubatsira.
Rafael aive mumwezve akabatwa nerudzi urwu rwekurwiswa muBrazil. Maererano ne Cyber Threat Report 2021 zve soninwall, nyika yaive yepfumbamwe zvakanyanya kubatwa nekubiwa kwedata muna 2020, ki kweUnited States, South Africa, Italy, United Kingdom, Belgium, Mexico, Netherlands neCanada chete. Pakazara, Brazil yakatambura kupfuura 3.8 miriyoni ransomware kurwisa gore rakapera - pasi rose, nhamba yacho yaiva mamiriyoni 304.6.
Maererano nekutyisidzira intelligence report kubva Tarisa Point Software, sangano reBrazil riri kurwiswa, paavhareji, 803 nguva pasvondo, kurwisa 694 kurwiswa kwesangano pasi rose - izvi mumwedzi mitanhatu yapfuura chete. Uyezve, iyo data inoratidza kuti pakutanga kwaApril, Brazil yakaramba ichitambura nekubiwa kwedata, pamwe rudzikunuro kurwisa mu3,1% yemakambani ekuBrazil zvichienzaniswa ne2% yemasangano epasi rose.
Vatsvakurudzi kubva Tarisa Point Software zvakare fungidzira kuti, muna 2020, mutengo wekubira data US$20 bhiriyoni kumakambani pasi rose, yakatenderedza 75% kupfuura yakabhadharwa gore rapfuura.
Chii chinonzi ransomware attack? 5j1g5t
O kurwisa kwe ransomware kunoitika kana mushandisi akaita imwe mhando ye Software, yakagadzirwa nechinangwa chekubira data rako uye kuidzosera chete kuburikidza nekubhadhara mukutsinhana, sezvakaitika kuna Rafael. Matsotsi encrypt mafaera emushandisi kuti aite kuti asasvike kuti zvidaro zvinenge zvisingaiti dzidzivise pasina kubhadhara rudzikinuro.
Francisco Camargo, purezidhendi webhodhi re ABES (Brazilian Association of Software Companies), anotsanangura kuti pane chete nzira mbiri kudzoreredza data rakavharidzirwa mune a rudzikunuro kurwisa: kubhadhara mari yakakumbirwa mukutsinhana kiyi yekudzima mafaira kana kuburikidza External hard drives yakagadzirwa kare. Naizvozvo, Camargo anoyambira kuti “zvakakosha kuti masangano everuzhinji neakazvimirira ave nehurongwa hwakasimba hwekuita negadziriro yeparutivi, nemaitiro evakuru, matekinoroji akavimbika uye vanhu vakadzidziswa”.
Kuita kubira data, vanorwisa vanofanirwa kuita pinda mukombuta yemunhu akabatwa (kana kunetiweki yekambani, mune zvakakura-zvikuru) kuisa chirongwa chinokwanisa kuvharidzira mafaera ese pamushini iwoyo. Asi kupaza muchina, kana network, hazvisi nyore, saka vanofanirwa kunyengerera mushandisi kuti atore malware (Software zvakaipa) kana utachiona zvemichina yako.
Nekudaro, hapana angabvuma kudhawunirodha kana kuisa chinhu chakaita seizvi pakombuta yavo achiziva, ndosaka matsotsi achiisa social engineering, kunyengedza vanhu mupfungwa kuti vaite chimwe chinhu kana kuti vagovane mamwe mashoko akavanzika.
Nzira yakajairika parizvino ndeye kuburikidza phishing, kuita kuti mushandisi agoverane ruzivo rwakavanzika kana kudzvanya mafaera uye/kana zvinongedzo kuti atambure nekubirwa ransomware. Chimiro chakajairika che phishing iri kuburikidza nemaemail emanyepo, asi inogona zvakare kuve kuburikidza nemameseji mameseji, akadai seSMS neWhatsApp, pakati pevamwe

Kune mhando mbiri huru dze rudzikunuro kurwisa: imwe inosiya kombiyuta yakavharwa zvachose uye imwe inobvumira kuti muchina ushandiswe, asi nemafaira ose akavharidzirwa, sezvakaitika kuna Rafael, uyo aingokwanisa kushandisa notepad. Kana iyo matsotsi sarudza yekutanga sarudzo, nzira chete yekudzosera komputa ndeye kuronga uye kuisazve iyo inoshanda sisitimu inoshandiswa - mune iyi nyaya, mafaera ese anoguma arasika.
Kunyangwe paine zviitiko zvekubiwa kwedata senge zvaRafael, Pedro Diogenes, CTO (Technical Director) we CLM, anoyambira kuti kurwisa kudai chinangwa chayo chikuru kuwana mari (kunyanya ikozvino ne crypto-coins), ndosaka chinangwa chekurwisa chiri makambani.
Kutsvaga State of Ransomware 2021, yakaitwa na Sophos ine 5.400 IT (Information Technology) nyanzvi munyika makumi matatu dzakasiyana, kusanganisira Brazil, yakaratidza kuti makambani ayo 30% yevashandi ava vanoshanda akarohwa nekubiwa kwedata muna 37 - muongororo yakaitwa gore rapfuura, achitaura nezvekurwiswa muna 2020, iyo muzana yaive 2019%. Zvinoenderana netsvagiridzo, makumi mana neshanu muzana emasangano akatambura nekubirwa data muna 51 aive akakura, kubva pakati pe42 ne2020 vashandi.
Nzira yekuzvidzivirira sei kubva pakubirwa data? 631a
Danho rekutanga nderekugara uchiziva uye kusadzvanya pane zvinokanganisika zvinongedzo kana mafaera aunogamuchira neemail kana meseji. Kusavimba uye kutarisisa kwekutarisa kunogona kukuponesa kubva kune akati wandei ane njodzi mamiriro painternet.
Semuenzaniso, mune email yekubhangi ichikuzivisa nezvekubhadharwa kwebhiri ranonoka, unogona kugara uchitarisa kero yeari kugamuchira uye kubata mukuru wesangano. Kana phishing, pachave nekukanganisa kana mutsauko kubva pane chaiyo. Zvimwe chetezvo zvinoitika nekunongedza mawebhusaiti - kana ukadzvanya pane chinongedzo chinokutungamira kune peji, gara uchitarisa kero URL.
Zvisinei, isu vanhu tiri pasi pekukundikana uye, nekuda kwechikonzero chipi, tinogona kutsauswa nematsotsi, saka danho rechipiri nderekudyara mune yakanaka kuchengetedza sisitimu yekombuta yako kuti urege kubatwa chitsotsi. rudzikunuro kurwisa. Muchinoitika chaRafael, aitofanira kudzidza ichi chidzidzo nenzira yakashata zvikurusa inobvira.
Ndagara ndisina hanya nekuchengetedzwa kwekombiyuta. Pasinei nekushanda zvakananga pairi, handina kumbobvira ndaita backups nguva dzose kana kuva neantivirus yakanaka - Iniwo ndaigara ndakamisa Windows updates kubva muhusimbe.

Pasinei nekubatsira, antivirus zvega hazvina kukwana kuchengetedza vashandisi kubva kunjodzi dzemazuva ano, kusanganisira kubiwa kwedata. Chimwe chishandiso chinobatsira kudzivirira kurwiswa kwemhando dzakasiyana ndeye BDU (Endpoint Detect uye Mhinduro) yakaiswa mukushanda sisitimu - tekinoroji inoshanda sebhokisi dema, kurekodha uye kurekodha zviitiko munguva chaiyo.
Camargo anotsanangura kuti kuchengetedzwa kwemashoko Iyo tripod inogadzirwa tekinoroji, maitiro uye vanhu. Nzira yekudzivirira sei kurwiswa kubva ransomware Izvo zvakafanana kune chero imwe mhando yecyber kurwisa, mbiru nhatu dzinofanirwa kucherechedzwa kudzivirira kubiwa kwedata.
Nezve mbiru yekutanga (tekinoroji), Camargo inosimbisa kukosha kwekugadzirisa zvigadziriso uye makwapa akasvibirika chengetedzo kune ese masisitimu, shandisa kuchengetedza mhinduro EPP (Endpoint Dziviriro Platforme BDU (Endpoint Detection uye Mhinduro), kuita nguva dzose backups, uye nguva dzose shandisa chechipiri chekusimbisa chinhu.
Kana iri mbiru yechipiri (maitirwo), inoshandiswa kunyanya panyaya yemasangano, mazano anofanira kuva nawo Information Security Policy (PSI) yakajeka uye yakagadziridzwa, dzidza iyo GDPR (General Data Protection Law) uye uwane nzira dzekuishandisa nekukurumidza sezvinobvira, dzidzisa vashandi vose maererano nePSI yesangano uye nekuchengetedza ruzivo maitiro akanakisa.
Mbiru yekupedzisira (vanhu) ndiyo yakanyanya kusimba, sezvo vashandisi vanogona kuwira nyore kune social engineering matekiniki. Chengetedzo munyika yedhijitari haina kusiyana neiri munyika yenyama. Pakati pezvirongwa zviripo, Camargo inosimbisa kusavhura kana kudzvanya pane zvinongedzo mumaemail kubva kune vausingazive, usingakanganwe kukiya komputa kana usiri kuishandisa, kungwarira zvakanyanya kune mumwe munhu kune rumwe rutivi rwechidzitiro, uye kusatevedzera mumwe. data dzevanhu.
Diogenes anogovera mamwe matipi akanaka ekuita mudhijitari, sekusaisa pendrive yako mune chero komputa - uye kutarisa pendrives isiri yako neantivirus -, kugadzira ma akaoma (uye kusaagovana nevamwe vanhu), kudzivisa kupinda munzvimbo dzisingazivikanwe. (uye kana kupa kuri kwakanaka kwazvo, nyumwira), iva nezvakawanda chenjera paunenge uchidhawunirodha pawebhusaiti isingazivikanwe uye usaise zvirongwa zvepirated.
Pasinei nekubiwa kwedata kwaakatambura, Rafael haana kurasikirwa nemafaira akawanda akakosha, sezvo mazhinji acho akakwanisa kuitazve (mune nyaya yemifananidzo kana zvidimbu zvekugadzira) kana kupora nekuti akachengetwa mumaemail akatumirwa.
Iye zvino ndiri kugara ndichivandudza Windows uye kuchengeta yakanaka yakabhadharwa uye yakagadziridzwa antivirus. Iniwo ndinowanzoita backups akanyanya kukosha faira mavhiki emamwe masevhisi ekuchengetedza gore akadai seDropbox uye OneDrive
