Uyisebenzisa njani i-YARA ukufumanisa i-malware ephezulu

¿Uyisebenzisa njani i-YARA ukufumanisa i-malware ephezulu? Xa iinkqubo ze-antivirus zesiNtu zifikelela kwimida yazo kwaye abahlaseli batyibilika kuyo yonke i-crack enokwenzeka, isixhobo esiye sayimfuneko kwiilebhu zokuphendula izehlo siyadlala: I-YARA, "imela yaseSwitzerland" yokuzingela i-malwareIdizayinelwe ukuchaza iintsapho zesoftware ekhohlakeleyo isebenzisa iipateni ezibhaliweyo kunye neebhinari, ivumela ukuya ngaphaya kokuthelekisa i-hash elula.

Kwizandla ezichanekileyo, i-YARA ayisiyondawo yokufumana kuphela ayisiyiyo iisampulu ze-malware ezaziwayo kuphela, kodwa ukwahluka okutsha, ukuxhaphazwa kosuku lwe-zero, kunye nezixhobo ezikhubekisayo zorhwebo.Kweli nqaku, siza kuphonononga nzulu kwaye sisebenzise i-YARA ekubhaqweni kwe-malware, indlela yokubhala imithetho eyomeleleyo, indlela yokuyivavanya, indlela yokuyidibanisa kumaqonga afana neVeeam okanye uhlalutyo lwakho lokuhamba komsebenzi, kwaye zeziphi iindlela ezilungileyo ezilandelwa luluntu lobuchwephesha.

Yintoni i-YARA kwaye kutheni inamandla kangaka ekubhaqeni i-malware?

I-YARA imele "Kukho enye i-Recursive Acronym" kwaye iye yaba ngumgangatho we-de facto kuhlalutyo lwesisongelo ngenxa yokuba. Ivumela ukuchaza iintsapho ze-malware usebenzisa imithetho efundekayo, ecacileyo, kunye neguquguqukayo kakhulu.Endaweni yokuxhomekeka kuphela kutyikityo lwe-antivirus olungatshintshiyo, i-YARA isebenza ngeepatheni ozichazayo.

Ingcamango esisiseko ilula: umgaqo we-YARA uhlola ifayile (okanye imemori, okanye i-data stream) kwaye ukhangele ukuba uchungechunge lweemeko ludibene. iimeko ezisekwe kuluhlu lwamagama, ulandelelwano lwehexadecimal, intetho eqhelekileyo, okanye iimpawu zefayileUkuba imeko idibene, kukho "umdlalo" kwaye unokulumkisa, uthintele, okanye wenze uhlalutyo olunzulu.

Le ndlela ivumela amaqela okhuseleko Chonga kwaye uhlele i-malware yazo zonke iintlobo: iintsholongwane zakudala, iintshulube, iiTrojans, iransomware, i-webshell, i-cryptominers, i-macros enobungozi, nokunye okuninzi.Ayikhawulelwanga kwizandiso ezithile zefayile okanye iifomati, ngoko ke ikwabhaqa i-disguised executable nge-.pdf extension okanye ifayile ye-HTML equlethe i-webshell.

Ngaphaya koko, i-YARA sele idityaniswe kwiinkonzo ezininzi eziphambili kunye nezixhobo ze-cybersecurity ecosystem: I-VirusTotal, iibhokisi zesanti ezifana neCuckoo, amaqonga agcinayo njengeVeeam, okanye izisombululo zokuzingela ezisongelayo ezivela kubavelisi abakumgangatho ophezuluKe ngoko, ukuqonda i-YARA kuye kwaphantse kwaba yimfuneko kubahlalutyi abaphambili kunye nabaphandi.

Iimeko zokusetyenziswa okuphezulu kwe-YARA ekubhaqweni kwe-malware

Enye yamandla e-YARA kukuba ilungelelanisa njengeglavu kwiimeko ezininzi zokhuseleko, ukusuka kwi-SOC ukuya kwilebhu ye-malware. Kwale mithetho ifanayo iyasebenza kuzo zombini ukuzingela kanye nokubeka iliso rhoqo..

Elona tyala lithe ngqo libandakanya ukudala imigaqo ethile ye-malware okanye iintsapho zonkeUkuba umbutho wakho uhlaselwa yiphulo elisekelwe kwintsapho eyaziwayo (umzekelo, i-trojan yokufikelela kude okanye isongelo se-APT), unokwazi ukwenza iphrofayili imitya yeempawu kunye neepatheni kwaye uphakamise imigaqo echonga ngokukhawuleza iisampuli ezintsha ezinxulumeneyo.

Olunye usetyenziso lwakudala lugxininiso lwe I-YARA isekelwe kwiisigneshaLe migaqo yenzelwe ukufumana i-hashes, imitya yokubhaliweyo ethe ngqo, iziqwengana zekhowudi, izitshixo zobhaliso, okanye ulandelelwano oluthile lwe-byte oluphindwayo kwiintlobo ezininzi ze-malware efanayo. Nangona kunjalo, khumbula ukuba ukuba ukhangela kuphela imitya encinci, ubeka umngcipheko wokuvelisa izinto ezingezizo.

I-YARA ikwaqaqambile xa isiza kuhluzo iintlobo zefayile okanye iimpawu zesakhiwoKuyenzeka ukuba wenze imigaqo esebenzayo kwi-PE executables, amaxwebhu e-ofisi, ii-PDF, okanye phantse nayiphi na ifomathi, ngokudibanisa iintambo ezineempawu ezifana nobukhulu befayile, iiheader ezithile (umzekelo, i-0x5A4D ye-PE executables), okanye ukungenisa umsebenzi okrokrelayo.

Kwiindawo zanamhlanje, ukusetyenziswa kwayo kunxulunyaniswa ne inteligencia de amenazasIingxelo zoluntu, iingxelo zophando, kunye nokutya kwe-IOC ziguqulelwa kwimithetho ye-YARA ehlanganiswe kwi-SIEM, i-EDR, iiplatifomu zokugcina, okanye iibhokisi zesanti. Oku kuvumela imibutho ukuba ngokukhawuleza ukubona izoyikiso ezivelayo ezabelana ngeempawu kunye namaphulo asele ehlalutyiwe.

Ukuqonda i-syntax yemithetho ye-YARA

I-syntax ye-YARA iyafana naleyo ka-C, kodwa ngendlela elula negxininise ngakumbi. Umgaqo ngamnye unegama, icandelo lemethadatha elikhethiweyo, icandelo lomtya, kwaye, ngokuyimfuneko, icandelo lemeko.Ukusuka apha ukuya phambili, amandla alele kwindlela odibanisa ngayo yonke loo nto.

Lo primero es el lawula igamaKufuneka ihambe kanye emva kwegama elingundoqo rule (o regla Ukuba ubhala ngeSpanish, nangona igama elingundoqo kwifayile liya kuba rulekwaye kufuneka ibe sisazisi esisebenzayo: akukho zithuba, akukho manani, kwaye akukho underscore. Kungumbono olungileyo ukulandela ingqungquthela ecacileyo, umzekelo into efana I-Malware_Iyantlukwano_Yosapho o APT_Umdlali_Isixhobo, ekuvumela ukuba uchonge ngokukrwaqula oko kujongwe ukubhaqa.

Okulandelayo kuza icandelo stringsapho uchaza iipateni ofuna ukuziphendla. Apha ungasebenzisa iintlobo ezintathu eziphambili: Imitya yokubhaliweyo, ulandelelwano lwe-hexadecimal, kunye nentetho eqhelekileyoImitya yokubhaliweyo ilungele iziqwengana zekhowudi ezifundeka ngabantu, ii-URL, imiyalezo yangaphakathi, amagama endlela, okanye iiPDB. Iihexadecimals zikuvumela ukuba ubambe iipateni ze-byte ekrwada, eziluncedo kakhulu xa ikhowudi ibonakalisiwe kodwa igcina ulandelelwano oluthile oluqhubekayo.

Iintetho eziqhelekileyo zibonelela ngokuguquguquka xa ufuna ukugubungela utshintsho oluncinci kumtya, njengokutshintsha imimandla okanye iindawo ezitshintshwe kancinci zekhowudi. Ngaphaya koko, yomibini imitya kunye ne-regex ivumela ukubaleka ukumela ii-bytes ezingafanelekanga, evula umnyango kwiipateni ze-hybride ezichanekileyo.

La sección condition Nguwo kuphela ogunyazisiweyo kwaye uchaza xa umthetho uthathwa ngokuba "uhambelana" nefayile. Apho usebenzisa imisebenzi yeBoolean kunye ne-arithmetic (kwaye, okanye, hayi, +, -, *, /, nayiphi na, yonke, iqulathe, njl.) ukuvakalisa ingqiqo yobhaqo ephucukileyo kunelula "ukuba lo mtya uyavela".

Umzekelo, ungakhankanya ukuba umgaqo uyasebenza kuphela ukuba ifayile incinci kunobungakanani obuthile, ukuba zonke iintambo ezibalulekileyo zivela, okanye ukuba enye yeentambo ezininzi ikhona. Unokudibanisa iimeko ezifana nobude bomtya, inani leematshisi, ii-offsets ezithile kwifayile, okanye ubungakanani befayile ngokwayo.Ukuyila apha kwenza umahluko phakathi kwemithetho yegeneric kunye nokubhaqwa kotyando.

Ekugqibeleni, unecandelo lokuzikhethela metaIfanelekile ekubhalweni ixesha. Kuqhelekile ukubandakanya umbhali, umhla wokudala, inkcazelo, inguqulelo yangaphakathi, ireferensi yeengxelo okanye amatikiti kwaye, ngokubanzi, naluphi na ulwazi olunceda ukugcina indawo yokugcina ihlelekile kwaye iyaqondakala kwabanye abahlalutyi.

Imizekelo esebenzayo yemithetho ye-YARA ephezulu

Ukubeka konke oku kungasentla kwimbono, kuyanceda ukubona indlela umthetho olula omiswe ngayo kwaye uba nzima njani xa iifayile eziphunyeziweyo, ukungenisa elizweni okukrokrisayo, okanye ulandelelwano lwemiyalelo oluphindaphindwayo luqala ukudlala. Masiqale ngerula yokudlala kwaye ngokuthe ngcembe sandise ubungakanani..

Umgaqo omncinci unokuqulatha kuphela umtya kunye nemeko eyenza kube yimfuneko. Umzekelo, unokukhangela umtya othile wokubhaliweyo okanye ummeli wolandelelwano lwe-byte yeqhekeza le-malware. Umqathango, kuloo meko, unokuchaza nje ukuba umgaqo ufezekisiwe ukuba loo mtya okanye ipateni ibonakala., ngaphandle kwezinye izihluzi.

Nangona kunjalo, kwiisetingi zehlabathi lokwenyani oku kuyawa ngokufutshane, kuba Amatyathanga alula ahlala evelisa izinto ezininzi zobuxokiYiyo loo nto kuqhelekile ukudibanisa imitya emininzi (okubhaliweyo kunye ne-hexadecimal) kunye nezithintelo ezongezelelweyo: ukuba ifayile ayidluli ubungakanani obuthile, ukuba iqulethe iiheader ezithile, okanye isebenze kuphela ukuba ubuncinane umtya omnye kwiqela ngalinye elichaziweyo lifunyenwe.

Umzekelo oqhelekileyo kuhlalutyo olusebenzisekayo lwe-PE ubandakanya ukungenisa imodyuli pe isuka ku YARA, ekuvumela ukuba ubuze iimpawu zangaphakathi zokubini: imisebenzi ethathwa ngaphandle, amacandelo, izitampu zamaxesha, njl. njl. CreateProcess desde Kernel32.dll kunye nomsebenzi othile weHTTP ukusuka iwininet.dll, ngaphezu kokuqulatha umtya othile obonisa ukuziphatha okungalunganga.

Olu hlobo lwengqiqo lufanelekile ekufumaneni indawo IiTrojans ezinoqhagamshelo olukude okanye amandla okukhuphanaxa amagama efayile okanye iindlela zitshintsha ukusuka kwelinye iphulo ukuya kwelinye. Into ebalulekileyo kukugxila kwindlela yokuziphatha ephantsi: ukudalwa kwenkqubo, izicelo ze-HTTP, i-encryption, ukuzingisa, njl.

Enye indlela esebenzayo kakhulu kukujonga i Ulandelelwano lwemiyalelo ephindaphindwayo phakathi kweesampuli ezivela kusapho olunye. Nokuba ngaba abahlaseli bapakishe okanye bayayifihla ibini, bahlala besebenzisa iinxalenye zekhowudi ekunzima ukuzitshintsha. Ukuba, emva kohlalutyo lwe-static, ufumana iibhloko zemiyalelo rhoqo, unokwenza umgaqo kunye wildcards kwimitya enehexadecimal leyo ibamba loo pateni ngelixa igcina unyamezelo oluthile.

Ngale mithetho “yendlela yokuziphatha esekwe kwikhowudi” iyenzeka jonga onke amaphulo e-malware afana nalawo ePlugX/Korplug okanye ezinye iintsapho ze-APTAwufumani nje i-hash ethile, kodwa ulandela isitayile sophuhliso, ukuze uthethe, sabahlaseli.

Ukusetyenziswa kweYARA kumaphulo okwenyani kunye nezoyikiso zosuku lwe-zero

I-YARA ibonakalise ukubaluleka kwayo ngakumbi kwicandelo lezoyikiso eziphambili kunye nokuxhaphaza kweentsuku zero, apho iindlela zokukhusela zakudala zifika kade kakhulu. Umzekelo owaziwayo kukusetyenziswa kweYARA ukufumana ixhoba kwiSilverlight ukusuka kubukrelekrele obuvuzayo obuncinci..

Kwimeko apho, kwii-imeyile ezibiweyo kwinkampani ezinikele ekuphuhliseni izixhobo ezikhubekisayo, iipateni ezaneleyo zagqitywa ukwakha umgaqo ojoliswe ekuxhatshazweni okuthile. Ngalo mgaqo mnye, abaphandi bakwazile ukulandelela isampuli kulwandle lweefayile ezikrokrelayo.Chonga i-exploit kwaye unyanzelise ukubamba kwayo, ukuthintela umonakalo omkhulu ngakumbi.

Ezi ntlobo zamabali zibonisa indlela i-YARA inokusebenza ngayo umnatha wokuloba kulwandle lweefayileYiba nomfanekiso wenethiwekhi yakho yenkampani njengolwandle olugcwele "iintlanzi" (iifayile) zazo zonke iintlobo. Imithetho yakho ifana namagumbi kumnatha wokuloba: igumbi ngalinye ligcina intlanzi ehambelana neempawu ezithile.

Xa ugqiba ukutsala, unayo iisampulu eziqokelelwe ngokufana kwiintsapho ezithile okanye amaqela abahlaseli: "ifana ne-Species X", "ifana ne-Species Y", njl njl. Ezinye zezi sampuli zinokuba zintsha ngokupheleleyo kuwe (amabini amatsha, amaphulo amatsha), kodwa zingena kwipatheni eyaziwayo, eyenza isantya sohlelo lwakho kunye nempendulo.

Ukufumana okuninzi kwi-YARA kulo mongo, imibutho emininzi iyadibanisa uqeqesho olukwizinga eliphezulu, iilabhoratri zepraktikhali kunye nemimandla yovavanyo elawulwayoKukho iikhosi ezikhethekileyo ezinikezelwe kuphela kubugcisa bokubhala imithetho elungileyo, ehlala isekelwe kumatyala okwenene e-cyber espionage, apho abafundi baziqhelanisa nesampulu eziyinyani kwaye bafunde ukukhangela "into" naxa bengayazi eyona nto bayikhangelayo.

Hlanganisa i-YARA kwi-backup kunye neqonga lokubuyisela

Enye indawo apho i-YARA ingena ngokugqibeleleyo, kwaye ihlala ingaqatshelwanga, kukhuseleko lwee-backups. Ukuba ii-backups zosulelwe yi-malware okanye i-ransomware, ukubuyisela kunokuqalisa kwakhona iphulo lonke.Yiyo loo nto abanye abavelisi befake iinjini ze-YARA ngokuthe ngqo kwizisombululo zabo.

Iiplatifti zokuxhasa isizukulwana esilandelayo zinokusungulwa Iiseshoni zokuhlalutya ezisekelwe kumgaqo we-YARA kumanqaku okubuyiselaIinjongo zimbini: kukufumana indawo yokugqibela "ecocekileyo" phambi kwesiganeko kunye nokubhaqa umxholo ongalunganga ofihlwe kwiifayile ekusenokwenzeka ukuba azizange ziqalwe zezinye iitshekhi.

Kwezi meko-bume inkqubo eqhelekileyo ibandakanya ukukhetha ukhetho lwe "Skena amanqaku okubuyisela ngerula ye-YARA"ngexesha lokucwangciswa komsebenzi wokuhlalutya. Okulandelayo, indlela eya kwifayile yemigaqo icacisiwe (ngokuqhelekileyo kunye nokwandiswa .yara okanye .yar), egcinwa ngokuqhelekileyo kwifolda yoqwalaselo olukhethekileyo kwisisombululo sokulondoloza."

Ngexesha lokubulawa, i-injini iphindaphinda izinto eziqulethwe kwikopi, isebenzisa imigaqo, kwaye Irekhoda yonke imidlalo kwilog yohlalutyo lwe-YARA.Umlawuli unokujonga ezi logs ukusuka kwikhonsoli, uphonononge izibalo, ubone ukuba zeziphi iifayile ezibangele isilumkiso, kwaye nokuba ulandelele ukuba ngabaphi oomatshini kunye nomhla othile umdlalo ngamnye ohambelana nawo.

Olu hlanganiso luncediswa zezinye iindlela ezifana ukufunyaniswa okungaqhelekanga, ukujonga ubungakanani bogcino, ukukhangela ii-IOC ezithile, okanye uhlalutyo lwezixhobo ezikrokrisayoKodwa xa kufikwa kwimithetho eyenzelwe usapho oluthile lwe-ransomware okanye iphulo, i-YARA sesona sixhobo silungileyo sokucokisa olo phendlo.

Uyivavanya njani kwaye uyiqinisekise imithetho ye-YARA ngaphandle kokwaphula inethiwekhi yakho

Nje ukuba uqalise ukubhala eyakho imithetho, inyathelo elilandelayo elibalulekileyo kukuvavanya ngocoselelo. Umthetho onobundlongo-ndlongo ogqithisileyo unokuvelisa iziphumo ezingezizo ezingeyonyani, ngelixa umntu oyekelela ngokugqithisileyo enokuvumela izoyikiso zokwenyani zidlule.Yiyo loo nto isigaba sovavanyo sibaluleke njengesigaba sokubhala.

Iindaba ezimnandi zezokuba awudingi kuseka ilebhu egcwele i-malware esebenzayo kwaye wosulele isiqingatha senethiwekhi ukwenza oku. Iindawo zokugcina kunye neeseti zedatha sele zikhona ezinikezela ngolu lwazi. iisampulu ezaziwayo nezilawulwayo ze-malware ngeenjongo zophandoUnokuzikhuphela ezo sampuli kwindawo ekwanti kwaye uzisebenzise njengovavanyo lwemithetho yakho.

Indlela eqhelekileyo kukuqala ngokusebenzisa iYARA ekuhlaleni, ukusuka kumgca womyalelo, ngokuchasene nolawulo oluqulathe iifayile ezikrokrisayo. Ukuba imithetho yakho ihambelana nalapho kufanele kwaye ingaphumi kwiifayile ezicocekileyo, ukwindlela elungileyo.Ukuba zibangela kakhulu, lixesha lokuphonononga iintambo, ukucokisa iimeko, okanye ukwazisa izithintelo ezongezelelweyo (ubungakanani, ukungenisa elizweni, ukuchithwa, njl.).

Enye inqaku eliphambili kukuqinisekisa ukuba imithetho yakho ayiphazamisi ukusebenza. Xa uskena abalawuli abakhulu, ii-backups ezigcweleyo, okanye ingqokelela yeesampulu ezinkulu, Imithetho engalungiswanga kakuhle inokucothisa uhlalutyo okanye isebenzise izixhobo ezingaphezulu kunoko unqwenelayo.Ke ngoko, kuyacetyiswa ukulinganisa amaxesha, ukwenza lula amabinzana antsokothileyo, kwaye unqande i-regex enzima kakhulu.

Emva kokudlula kweso sigaba sovavanyo lwebhubhoratri, uya kukwazi Ukukhuthaza imithetho kubume bemvelisoNokuba ikwi-SIEM yakho, iinkqubo zakho zogcino, iiseva ze-imeyile, okanye naphi na apho ufuna ukuzidibanisa. Kwaye ungalibali ukugcina umjikelo wophononongo oqhubekayo: njengoko amaphulo eguquka, imithetho yakho iya kufuna uhlengahlengiso ngamaxesha athile.

Izixhobo, iinkqubo kunye nokuhamba komsebenzi kunye ne-YARA

Ngaphaya kokubini okusemthethweni, uninzi lweengcali ziye zaphuhlisa iinkqubo ezincinci kunye nemibhalo ejikeleze i-YARA ukuququzelela ukusetyenziswa kwayo kwemihla ngemihla. Indlela eqhelekileyo ibandakanya ukwenza isicelo hlanganisa eyakho ikhithi yokhuseleko efunda ngokuzenzekelayo yonke imigaqo kwifolda kwaye iyisebenzise kulawulo lohlalutyo.

Ezi ntlobo zezixhobo zasekhaya zihlala zisebenza kunye nesakhiwo esilula solawulo: incwadi enye ye imithetho ekhutshelwe kwi-Intanethi (umzekelo, “rulesyar”) kunye nenye incwadi eneenkcukacha iifayile ezikrokrelekayo eziya kuhlalutywa (umzekelo, "i-malware"). Xa udweliso lwenkqubo luqala, lujonga ukuba zombini iifolda zikhona, dwelisa imithetho kwisikrini, kwaye lulungiselela ukwenziwa.

Xa ucofa iqhosha elifana ne “Qala ukujongaIsicelo siqalise i-YARA ephunyeziweyo kunye neeparamitha ezifunwayo: ukuskena zonke iifayile kwifolda, uhlalutyo oluphinda-phindayo lwe-subdirectories, izibalo ezikhuphayo, i-metadata yokushicilela, njl. njl.

Oku kuhamba komsebenzi kuvumela, umzekelo, ukufunyanwa kwemiba kwibhetshi yee-imeyile ezithunyelwa ngaphandle. imifanekiso elungisiweyo eyingozi, uncamathiselo oluyingozi, okanye amaqokobhe ewebhu afihlwe kwiifayile ezibonakala zingenabungoziUphando oluninzi lwasenkundleni kwiindawo zeshishini luxhomekeke ngokuchanekileyo kolu hlobo lomatshini.

Ngokumalunga neyona parameters iluncedo xa ubiza i-YARA, ukhetho olunjengolu lulandelayo lugqamile: -r ukukhangela ngokuphindaphindiweyo, -S ukubonisa izibalo, -m ukukhupha imetadata, kunye -w ukungahoyi izilumkisoNgokudibanisa ezi flegi ungalungelelanisa impatho kwimeko yakho: ukusuka kuhlalutyo olukhawulezayo kulawulo oluthile ukuya kuvavanyo olupheleleyo lwesakhiwo sefolda enzima.

Iindlela ezilungileyo xa ubhala kwaye ugcina imithetho ye-YARA

Ukuthintela uvimba wakho wemithetho ekubeni ube bubugqwirha obungalawulekiyo, kuyacetyiswa ukuba usebenzise uthotho lwezona ndlela zilungileyo. Eyokuqala kukusebenza ngeetemplates ezihambelanayo kunye nemigaqo yamagamaukuze nawuphi na umhlalutyi anokuqonda ngokukrwaqula into eyenziwa ngumgaqo ngamnye.

Amaqela amaninzi amkela ifomathi eqhelekileyo ebandakanya Isihloko esinemethadatha, iithegi ezibonisa uhlobo lwesisongelo, umdlali okanye iqonga, kunye nenkcazo ecacileyo yento ebhaqiweyo.Oku akuncedi ngaphakathi kuphela, kodwa naxa usabelana ngemithetho noluntu okanye ufaka isandla kwiindawo zokugcina uluntu.

Enye ingcebiso kukuhlala uyikhumbula loo nto I-YARA ngomnye nje umaleko wokuzikhuselaAyithathi indawo yesoftware ye-antivirus okanye i-EDR, kodwa kunoko iyabancedisa kwizicwangciso Khusela iWindows PC yakhoNgokunqwenelekayo, i-YARA kufuneka ilingane phakathi kwezakhelo zereferensi ezibanzi, ezifana nesakhelo se-NIST, esikwajongana nokuchongwa kwe-asethi, ukhuseleko, ukubhaqwa, ukuphendula, kunye nokubuyiselwa.

Ukusuka kumbono wobugcisa, kuyafaneleka ukunikezela ixesha evitar falsos positivosOku kubandakanya ukuphepha imitya eqhelekileyo, ukudibanisa iimeko ezininzi, kunye nokusetyenziswa kwabaqhubi ezifana all of o any of Sebenzisa intloko yakho kwaye uthathe inzuzo yezakhiwo zefayile. Okukhona ingqiqo ejikeleze i-malware, ingcono.

Okokugqibela, gcina uqeqesho lwe uguqulelo kunye nophononongo lwamaxesha ngamaxesha Ibalulekile. Iintsapho ze-Malware ziyavela, izikhombisi ziyatshintsha, kwaye imithetho esebenzayo namhlanje inokusilela okanye iphelelwe lixesha. Ukuphonononga kunye nokucokisa umthetho wakho oseti ngamaxesha yinxalenye yomdlalo wekati kunye nempuku wokhuseleko lwe-cyber.

Uluntu lweYARA kunye nezixhobo ezikhoyo

Esinye sezizathu eziphambili ze-YARA ukuza kuthi ga ngoku ngamandla oluntu lwayo. Abaphandi, iifemu zokhuseleko, kunye namaqela okuphendula avela kwihlabathi liphela abelana ngemithetho, imizekelo kunye namaxwebhu.ukudala i-ecosystem etyebe kakhulu.

Ingongoma ephambili ekubhekiselwa kuyo yi Indawo yokugcina esemthethweni ye-YARA kwi-GitHubApho uya kufumana iinguqulelo zamva nje zesixhobo, ikhowudi yemvelaphi, kunye namakhonkco kumaxwebhu. Ukusuka apho ungalandela inkqubela yeprojekthi, unike ingxelo ngemiba, okanye unikele ngophuculo ukuba uyathanda.

Amaxwebhu asemthethweni, afumaneka kumaqonga afana ne-ReadTheDocs, anikezela isikhokelo esipheleleyo se-syntax, iimodyuli ezikhoyo, imizekelo yomthetho, kunye neereferensi zokusetyenziswaIngumthombo obalulekileyo wokusebenzisa imisebenzi ephezulu kakhulu, njengokuhlolwa kwe-PE, i-ELF, imithetho yememori, okanye ukudibanisa nezinye izixhobo.

Ukongeza, kukho iindawo zokugcina uluntu lwemithetho ye-YARA kunye nokutyikitya apho abahlalutyi abavela kwihlabathi liphela Bapapasha ingqokelela esele ilungele ukusetyenziswa okanye ingqokelela enokuthi ilungelelaniswe neemfuno zakho.Ezi zixhobo zibandakanya imigaqo yosapho oluthile lwe-malware, izixhobo zokuxhaphaza, izixhobo ezisetyenziswa ngokukhohlakeleyo, ii-webshell, i-cryptominers, nokunye okuninzi.

Ngokuhambelanayo, abaninzi abavelisi kunye namaqela ophando anikezela Uqeqesho oluthe ngqo kwi-YARA, ukusuka kumanqanaba asisiseko ukuya kwizifundo eziphambili kakhuluLa manyathelo ahlala ebandakanya iilebhu zenyani kunye nokuzilolonga ngezandla okusekwe kwimeko yelizwe lokwenyani. Ezinye zide zinikezelwe simahla kwimibutho engenzi nzuzo okanye amaqumrhu asemngciphekweni wokuhlaselwa ekujoliswe kuwo.

Yonke le ecosystem ithetha ukuba, ngokuzinikela okuncinci, ungasuka ekubhaleni imithetho yakho yokuqala esisiseko ukuya phuhlisa iisuite eziphucukileyo ezikwaziyo ukulandelela amaphulo antsonkothileyo kunye nokufumanisa izoyikiso ezingazange zibonwe ngaphambiliKwaye, ngokudibanisa i-YARA kunye ne-antivirus yemveli, i-backup ekhuselekileyo, kunye nobukrelekrele bezoyikiso, wenza izinto zibe nzima kakhulu kubadlali abakhohlakeleyo abazulazula kwi-intanethi.

Ngayo yonke le nto ingentla, kucacile ukuba i-YARA ingaphezulu kwesixhobo esilula somyalelo: yi pieza clave kulo naliphi na iqhinga eliphambili lokubona i-malware, isixhobo esiguqukayo esiziqhelanisa nendlela yakho yokucinga njengomhlalutyi kunye Ulwimi oluqhelekileyo edibanisa iilabhoratri, ii-SOC kunye noluntu lophando kwihlabathi jikelele, ukuvumela umthetho omtsha ngamnye ukuba wongeze omnye umaleko wokhuseleko kumaphulo anobunkunkqele.
