Isetshenziswa kanjani i-YARA ukuthola i-malware ethuthukisiwe

¿Isetshenziswa kanjani i-YARA ukuthola i-malware ethuthukisiwe? Lapho izinhlelo ezivamile zokulwa namagciwane zifinyelela umkhawulo wazo futhi abahlaseli bangena kuwo wonke ama-crack, ithuluzi eselibaluleke kakhulu kumalebhu okuphendula izigameko liyaqala ukusebenza: I-YARA, “ummese we-Swiss” wokuzingela uhlelo olungayilungele ikhompuyuthaIdizayinelwe ukuchaza imindeni yesoftware enonya kusetshenziswa amaphethini ombhalo namaphethini kanambambili, ivumela ukuya ngale kokumatanisa kwe-hashi okulula.

Ezandleni ezifanele, i-YARA akuyona nje indawo hhayi kuphela amasampuli aziwa ngohlelo olungayilungele ikhompuyutha, kodwa nezinhlobonhlobo ezintsha, ukuxhashazwa kosuku oluyiziro, kanye namathuluzi ahlaselayo ezentengiselwano.Kulesi sihloko, sizohlola ngokujulile futhi ngokoqobo ukuthi i-YARA isetshenziswa kanjani ukuze kutholwe uhlelo olungayilungele ikhompuyutha, ibhalwa kanjani imithetho eqinile, ihlolwa kanjani, ungayihlanganisa kanjani nezinkundla ezifana ne-Veeam noma ukuhamba kwakho komsebenzi kokuhlaziya, kanye nokuthi iziphi izinqubo ezinhle ezilandelwa umphakathi wochwepheshe.

Iyini i-YARA futhi kungani inamandla kangaka ekutholeni uhlelo olungayilungele ikhompuyutha?

I-YARA imele ukuthi “Yet Another Recursive Acronym” futhi isiphenduke indinganiso yokuhlaziya usongo ngoba Ivumela ukuchaza imindeni yohlelo olungayilungele ikhompuyutha isebenzisa imithetho efundekayo, ecacile, nevumelana nezimo kakhulu.Esikhundleni sokuthembela kuphela kusiginisha esilwa namagciwane esimile, i-YARA isebenza namaphethini ozichaza wona.

Umbono oyisisekelo ulula: umthetho we-YARA uhlola ifayela (noma inkumbulo, noma ukusakazwa kwedatha) futhi uhlole ukuthi uchungechunge lwezimo luyahlangatshezwa yini. izimo ezisekelwe kuyunithi yezinhlamvu zombhalo, ukulandelana kwe-hexadecimal, izengezo ezivamile, noma izici zefayelaUma isimo sihlangatshezwana, kukhona "ukufanisa" futhi ungakwazi ukuxwayisa, ukuvimba, noma ukuhlaziya okujulile.

Le ndlela ivumela amaqembu ezokuphepha Khomba futhi uhlukanise uhlelo olungayilungele ikhompuyutha lwazo zonke izinhlobo: amagciwane akudala, izikelemu, amaTrojan, i-ransomware, ama-webshell, ama-cryptominers, ama-malicious macros, nokunye okuningi.Ayikhawulelwe ezandisweni zefayela ezithile noma amafomethi, ngakho futhi ithola okusebenzisekayo okufihliwe ngesandiso se-.pdf noma ifayela le-HTML eliqukethe igobolondo lewebhu.

Ngaphezu kwalokho, i-YARA isivele ihlanganiswe ezinhlelweni eziningi ezibalulekile namathuluzi we-cybersecurity ecosystem: I-VirusTotal, ama-sandbox afana ne-Cuckoo, izinkundla eziyisipele njenge-Veeam, noma izixazululo zokuzingela ezisongelayo ezivela kubakhiqizi bezinga eliphezuluNgakho-ke, ukwazi i-YARA sekucishe kube yimfuneko kubahlaziyi nabacwaningi abathuthukile.

Izimo zokusetshenziswa okuthuthukisiwe kwe-YARA ekutholweni kwe-malware

Enye yamandla e-YARA ukuthi ijwayela njengegilavu ​​kuzimo eziningi zokuphepha, ukusuka ku-SOC kuya elebhu ye-malware. Imithetho efanayo iyasebenza kukho kokubili ukuzingela kanye kanye nokuqapha okuqhubekayo..

Icala eliqondile kakhulu libandakanya ukudala imithetho ethile yohlelo olungayilungele ikhompuyutha noma imindeni yonkeUma inhlangano yakho ihlaselwa umkhankaso osuselwe kumndeni owaziwayo (isibonelo, i-trojan yokufinyelela kude noma usongo lwe-APT), ungakwazi ukufaka iphrofayela iyunithi yezinhlamvu zesici namaphethini futhi uphakamise imithetho ehlonza ngokushesha amasampula amasha ahlobene.

Okunye ukusetshenziswa kwakudala ukugxila kwe I-YARA esekelwe kumasigineshaLe mithetho yakhelwe ukuthola ama-hashes, izintambo zombhalo ezicaciswe kakhulu, amazwibela ekhodi, okhiye bokubhalisa, noma nokulandelana kwebhayithi okukhethekile okuphindwa ngezinhlobonhlobo eziningi zohlelo olungayilungele ikhompuyutha efanayo. Kodwa-ke, khumbula ukuthi uma usesha izintambo ezincane kuphela, uzifaka engcupheni yokukhiqiza izinto ezingamanga.

I-YARA iphinde ikhanye uma kukhulunywa ngokuhlunga izinhlobo zamafayela noma izici zesakhiwoKungenzeka ukudala imithetho esebenza kokusebenzisekayo kwe-PE, imibhalo yasehhovisi, ama-PDF, noma cishe noma iyiphi ifomethi, ngokuhlanganisa izintambo ezinezakhiwo ezifana nosayizi wefayela, izihloko ezithile (isb., 0x5A4D yezinto ezisebenzisekayo ze-PE), noma ukungenisa okusolisayo komsebenzi.

Ezimweni zanamuhla, ukusetshenziswa kwayo kuxhumene ne inteligencia de amenazasAmakhosombe asesidlangalaleni, imibiko yocwaningo, kanye nokuphakelayo kwe-IOC kuhunyushwa emithethweni ye-YARA ehlanganiswe ku-SIEM, EDR, izinkundla eziyisipele, noma amabhokisi esihlabathi. Lokhu kuvumela izinhlangano ukuthi thola ngokushesha izinsongo ezivelayo ezabelana nezici nemikhankaso esihlaziyiwe.

Ukuqonda i-syntax yemithetho ye-YARA

I-syntax ye-YARA ifana ncamashi neka-C, kodwa ngendlela elula negxile kakhulu. Umthetho ngamunye uqukethe igama, isigaba semethadatha ozikhethela sona, isigaba seyunithi yezinhlamvu, futhi, ngempela, isigaba semibandela.Kusukela lapha kuya phambili, amandla alele ekutheni ukuhlanganisa kanjani konke lokho.

Lo primero es el igama lomthethoKufanele ihambe ngemuva kwegama elingukhiye rule (o regla Uma ubhala ngeSpanishi, nakuba igama elingukhiye efayeleni lizoba rulefuthi kufanele kube inkomba evumelekile: azikho izikhala, azinanombolo, futhi azikho i-underscore. Kungumqondo omuhle ukulandela umhlangano ocacile, isibonelo into efana nale I-Malware_Varian_Yomndeni o APT_Actor_Tool, okukuvumela ukuthi ubone nje ukuthi ihloselwe ukuhlonza ini.

Okulandelayo kuza isigaba stringslapho uchaza khona amaphethini ofuna ukuwacinga. Lapha ungasebenzisa izinhlobo ezintathu eziyinhloko: iyunithi yezinhlamvu zombhalo, ukulandelana kwe-hexadecimal, nezinkulumo ezivamileIzinhlamvu zombhalo zilungele amazwibela ekhodi afundeka umuntu, ama-URL, imilayezo yangaphakathi, amagama ezindlela, noma ama-PDB. Ama-hexadecimals akuvumela ukuthi uthwebule amaphethini ebhayithi eluhlaza, awusizo kakhulu uma ikhodi i-obfuscated kodwa egcina ukulandelana okuthile okungaguquki.

Izinkulumo ezivamile zinikeza ukuguquguquka lapho udinga ukumboza ukuhluka okuncane kuyunithi yezinhlamvu, njengokushintsha izizinda noma izingxenye ezishintshwe kancane zekhodi. Ngaphezu kwalokho, zombili izintambo kanye ne-regex zivumela ukuphunyuka ukuthi kumelele amabhayithi akhethekile, okuvula umnyango wamaphethini we-hybrid anembe kakhulu.

La sección condition Iwukuphela kwesibopho futhi ichaza lapho umthetho ubhekwa "njengokufanisa" ifayela. Lapho usebenzisa imisebenzi ye-Boolean ne-arithmetic (futhi, noma, hhayi, +, -, *, /, noma yikuphi, konke, kuqukethe, njll.) ukuveza ukuqonda kahle kokuthola kunento elula "uma le yunithi yezinhlamvu ivela".

Isibonelo, ungacacisa ukuthi umthetho usebenza kuphela uma ifayela lincane kunosayizi othile, uma kuvela zonke izintambo ezibucayi, noma uma okungenani kukhona iyunithi yezinhlamvu eyodwa kwezimbalwa. Ungakwazi futhi ukuhlanganisa izimo ezifana nobude beyunithi yezinhlamvu, inombolo yokufanisa, ama-offset athile efayelini, noma usayizi wefayela ngokwalo.Ukudala lapha kwenza umehluko phakathi kwemithetho ejwayelekile kanye nokutholwa kokuhlinzwa.

Ekugcineni, unesigaba ongasikhetha metaIlungele ukubhala isikhathi. Kuvamile ukufaka umbhali, idethi yokudala, incazelo, inguqulo yangaphakathi, ireferensi yemibiko noma amathikithi futhi, ngokuvamile, noma yiluphi ulwazi olusiza ukugcina inqolobane ihlelekile futhi iqondakala kwabanye abahlaziyi.

Izibonelo ezisebenzayo zemithetho ye-YARA ethuthukisiwe

Ukubeka konke lokhu okungenhla ngombono, kuyasiza ukubona ukuthi umthetho olula wakhiwe kanjani nokuthi uba yinkimbinkimbi kanjani uma amafayela asebenzisekayo, ukungenisa ezweni okusolisayo, noma ukulandelana kwemiyalelo ephindaphindwayo kuqala. Ake siqale ngombusi wethoyizi futhi kancane kancane sandise usayizi..

Umthetho omncane ungaqukatha iyunithi yezinhlamvu kuphela kanye nesimo esiwenza ube yisibopho. Isibonelo, ungasesha iyunithi yezinhlamvu ethile yombhalo noma ummeleli webhayithi yokulandelana kwesiqephu sohlelo olungayilungele ikhompuyutha. Isimo, kuleso simo, singasho nje ukuthi umthetho uyafinyelelwa uma leyo ntambo noma iphethini ivela., ngaphandle kwezihlungi ezengeziwe.

Kodwa-ke, kuzilungiselelo zomhlaba wangempela lokhu kuyafinyela, ngoba Amaketanga alula ngokuvamile akhiqiza amaphuzu amaningi angamangaYingakho kuvamile ukuhlanganisa izintambo ezimbalwa (umbhalo kanye ne-hexadecimal) nemikhawulo eyengeziwe: ukuthi ifayela alidluli usayizi othile, ukuthi liqukethe izihloko ezithize, noma ukuthi lenziwa lisebenze kuphela uma okungenani iyunithi yezinhlamvu eyodwa eqenjini ngalinye elichaziwe.

Isibonelo esijwayelekile ekuhlaziyeni okusebenzisekayo kwe-PE sibandakanya ukungenisa imojuli pe kusuka ku-YARA, ekuvumela ukuthi ubuze izici zangaphakathi ze-binary: imisebenzi engenisiwe, izigaba, izitembu zesikhathi, njll. Umthetho othuthukisiwe ungadinga ukuthi ifayela lingeniswe DalaProcess kusukela Kernel32.dll kanye nomsebenzi othile we-HTTP kusuka i-wininet.dll, ngaphezu kokuqukatha iyunithi yezinhlamvu ethile ebonisa ukuziphatha okunonya.

Lolu hlobo lwe-logic luphelele ekutholeni indawo Ama-Trojan anoxhumo olukude noma amakhono okukhiphanoma ngabe amagama wefayela noma izindlela zishintsha zisuka komunye umkhankaso ziye komunye. Into ebalulekile ukugxila ekuziphatheni okuyisisekelo: ukudalwa kwenqubo, izicelo ze-HTTP, ukubethela, ukuphikelela, njll.

Enye indlela ephumelela kakhulu ukubheka ukulandelana kwemiyalelo ephindaphindwayo phakathi kwamasampula omndeni ofanayo. Ngisho noma abahlaseli bepakisha noma befiphaza kanambambili, bavame ukusebenzisa izingxenye zekhodi okunzima ukuzishintsha. Uma, ngemva kokuhlaziya okumile, uthola amabhlogo angaguquki emiyalo, ungakha umthetho ngawo ama-wildcards kuyunithi yezinhlamvu ze-hexadecimal lokho kubamba lelo phethini ngenkathi igcina ukubekezelelana okuthile.

Ngale mithetho "esuselwa ekuziphatheni kwekhodi" kungenzeka landelela yonke imikhankaso yohlelo olungayilungele ikhompuyutha efana naleyo ye-PlugX/Korplug noma eminye imindeni ye-APTAwutholi nje i-hashi ethile, kodwa ulandela isitayela sokuthuthukisa, ngomqondo ongokomfanekiso, sabahlaseli.

Ukusetshenziswa kwe-YARA emikhankasweni yangempela kanye nezinsongo zosuku oluyiziro

I-YARA ikufakazele ukubaluleka kwayo ikakhulukazi emkhakheni wezinsongo ezithuthukile kanye nokuxhashazwa kwezinsuku eziyiziro, lapho izindlela zokuvikela zakudala zifika sekwephuze kakhulu. Isibonelo esaziwa kakhulu ukusetshenziswa kwe-YARA ukuthola ukuxhashazwa ku-Silverlight kusuka kubuhlakani obuncane obuputshuziwe..

Kuleso simo, kusukela kuma-imeyili antshontshiwe enkampanini ezinikele ekuthuthukisweni kwamathuluzi ahlaselayo, amaphethini anele atholwa ukuze kwakhiwe umthetho oqondiswe ekuxhashazweni okuthile. Ngalowo mthetho owodwa, abacwaningi bakwazi ukulandelela isampula olwandle lwamafayela asolisayo.Khomba ukuxhaphaza futhi uphoqelele ukuchibiyela kwayo, ugweme umonakalo omkhulu kakhulu.

Lezi zinhlobo zezindaba zibonisa ukuthi i-YARA ingasebenza kanjani inetha lokudoba olwandle lwamafayelaCabanga ngenethiwekhi yakho yebhizinisi njengolwandle olugcwele "izinhlanzi" (amafayela) azo zonke izinhlobo. Imithetho yakho ifana nezingxenye ezinetha lokudonsa ngodobo: igumbi ngalinye ligcina izinhlanzi ezihambisana nezici ezithile.

Uma uqeda ukudonsa, usukwenzile amasampula aqoqwe ngokufana nemindeni ethile noma amaqembu abahlaseli: “efana ne-Species X”, “efana ne-Species Y”, njll. Amanye alawa masampuli angase abe masha ngokuphelele kuwe (okuhamba ngakubili okusha, imikhankaso emisha), kodwa angena kuphethini eyaziwayo, esheshisa ukuhlukaniswa kwakho nempendulo.

Ukuthola okuningi ku-YARA kulo mongo, izinhlangano eziningi ziyahlangana ukuqeqeshwa okuthuthukile, amalabhorethri asebenzayo kanye nezindawo zokuhlola ezilawulwayoKunezifundo ezikhethekile kakhulu ezinikezelwe ngokukhethekile kubuciko bokubhala imithetho emihle, ngokuvamile esekelwe ezimweni zangempela zobunhloli be-cyber, lapho abafundi bazijwayeza ngamasampula ayiqiniso futhi bafunde ukusesha "into" ngisho nalapho bengazi kahle ukuthi bafunani.

Hlanganisa i-YARA ibe yizinkundla zokwenza ikhophi yasenqolobaneni nezokubuyisela

Indawo eyodwa lapho i-YARA ingena khona kahle, futhi evame ukunganakwa ngandlela thile, ukuvikelwa kwezipele. Uma izipele zingenwe i-malware noma i-ransomware, ukubuyisela kungase kuqalise kabusha wonke umkhankaso.Kungakho abanye abakhiqizi befake izinjini ze-YARA ngqo kwizixazululo zabo.

Izinkundla zokwenza isipele zesizukulwane esilandelayo zingasungulwa Izikhathi zokuhlaziya ezisekelwe kumthetho we-YARA kumaphoyinti okubuyiselaUmgomo ukabili: ukuthola indawo yokugcina "ehlanzekile" ngaphambi kwesigameko kanye nokuthola okuqukethwe okunonya okufihlwe kumafayela okungenzeka ukuthi awazange aqalwe okunye ukuhlola.

Kulezi zindawo inqubo ejwayelekile ibandakanya ukukhetha inketho "Skena amaphuzu okubuyisela ngerula ye-YARA"phakathi nokucushwa komsebenzi wokuhlaziya. Okulandelayo, indlela eya efayeleni lemithetho iyacaciswa (ngokuvamile ngesandiso esithi .yara noma .yar), ngokuvamile egcinwa kufolda yokucushwa eqondene nesixazululo sokulondoloza."

Ngesikhathi sokubulawa, injini iphindaphinda izinto eziqukethwe ekhophi, isebenzisa imithetho, futhi Irekhoda yonke okufanayo kulogi ethile yokuhlaziya ye-YARA.Umlawuli angakwazi ukubuka lawa malogi kusukela kukhonsoli, abuyekeze izibalo, abone ukuthi yimaphi amafayela acuphe isexwayiso, futhi alandele ngisho nokulandelela ukuthi iyiphi imishini kanye nedethi ethile efanayo ehambisana nayo.

Lokhu kuhlanganiswa kuhambisana nezinye izindlela ezifana nalezi ukutholwa okudidayo, ukuqapha usayizi wesipele, ukusesha ama-IOC athile, noma ukuhlaziya amathuluzi asolisayoKepha uma kukhulunywa ngemithetho eklanyelwe umndeni othile we-ransomware noma umkhankaso, i-YARA iyithuluzi elingcono kakhulu lokucwenga lolo sesho.

Uyivivinya kanjani futhi uqinisekise imithetho ye-YARA ngaphandle kokuphula inethiwekhi yakho

Uma usuqale ukubhala eyakho imithetho, isinyathelo esilandelayo esibalulekile wukuvivinya kahle. Umthetho onolaka ngokweqile ungadala inqwaba yemibono engelona iqiniso, kuyilapho umuntu oxega ngokweqile angavumela izinsongo zangempela zidlule.Yingakho isigaba sokuhlola sibaluleke njengesigaba sokubhala.

Izindaba ezinhle ukuthi awudingi ukumisa ilebhu egcwele uhlelo olungayilungele ikhompuyutha futhi uthelele ingxenye yenethiwekhi ukuze wenze lokhu. Amakhosombe namadathasethi akhona kakade anikeza lolu lwazi. amasampuli aziwa futhi alawulwayo wohlelo olungayilungele ikhompuyutha ngezinjongo zocwaningoUngadawuniloda lawo masampuli endaweni engayodwa futhi uwasebenzise njengendawo yokuhlola yemithetho yakho.

Indlela evamile iwukuqala ngokusebenzisa i-YARA endaweni, kusukela kulayini womyalo, ngokumelene nenkomba equkethe amafayela asolisayo. Uma imithetho yakho ifana nalapho kufanele futhi ingagqekezi kalula amafayela ahlanzekile, usendleleni efanele.Uma zicupha kakhulu, yisikhathi sokubuyekeza izintambo, ukulungisa izimo, noma ukwethula imikhawulo eyengeziwe (usayizi, ukungenisa, ukukhishwa, njll.).

Elinye iphuzu elibalulekile ukuqinisekisa ukuthi imithetho yakho ayiphazamisi ukusebenza. Lapho uskena uhlu lwemibhalo emikhulu, izipele ezigcwele, noma amaqoqo amasampula amakhulu, Imithetho ethuthukiswe kabi inganciphisa ukuhlaziya noma isebenzise izinsiza eziningi kunalokho okulindele.Ngakho-ke, kuyatuseka ukukala izikhathi, ukwenza lula izisho eziyinkimbinkimbi, futhi ugweme i-regex esinda kakhulu.

Ngemva kokudlula kuleso sigaba sokuhlola ilabhorethri, uzokwazi Gqugquzela imithetho endaweni yokukhiqizaKungakhathaliseki ukuthi iku-SIEM yakho, izinhlelo zakho eziyisipele, amaseva e-imeyili, nanoma yikuphi lapho ofuna ukuwahlanganisa. Futhi ungakhohlwa ukugcina umjikelezo wokubuyekeza oqhubekayo: njengoba imikhankaso ishintsha, imithetho yakho izodinga ukulungiswa ngezikhathi ezithile.

Amathuluzi, izinhlelo nokuhamba komsebenzi nge-YARA

Ngaphandle kokusebenza kanambambili okusemthethweni, ochwepheshe abaningi benze izinhlelo ezincane nemibhalo ezungeze i-YARA ukuze kube lula ukusetshenziswa kwayo kwansuku zonke. Indlela ejwayelekile ihlanganisa ukudala isicelo hlanganisa ikhithi yakho yokuvikela efunda ngokuzenzakalelayo yonke imithetho kufolda futhi iyisebenzise kuhla lwemibhalo lokuhlaziya.

Lezi zinhlobo zamathuluzi enziwe ekhaya ngokuvamile zisebenza ngesakhiwo sohla lwemibhalo esilula: ifolda eyodwa ye- imithetho elandiwe ku-inthanethi (ngokwesibonelo, “rulesar”) nenye ifolda ye- amafayela asolisayo azohlaziywa (isibonelo, “i-malware”). Lapho uhlelo luqala, luhlola ukuthi womabili amafolda akhona, lubhala imithetho esibukweni, bese lulungiselela ukukhishwa.

Uma ucindezela inkinobho efana nokuthi “Qala ukuhlolaUhlelo lube sethula i-YARA esebenzisekayo ngemingcele efiselekayo: ukuskena wonke amafayela kufolda, ukuhlaziya okuphindaphindiwe kwemibhalo engaphansi, izibalo eziphumayo, imethadatha yokunyathelisa, njll. Noma yikuphi okufanayo kuboniswa efasiteleni lemiphumela, okubonisa ukuthi yiliphi ifayela elihambisana nomuphi umthetho.

Lokhu kugeleza komsebenzi kuvumela, isibonelo, ukutholwa kwezinkinga kuqoqo lama-imeyili athunyelwe. izithombe ezishumekiwe ezinonya, izinanyathiselwa eziyingozi, noma amagobolondo ewebhu afihlwe kumafayela abonakala emsulwaUphenyo oluningi lwe-forensic ezindaweni zebhizinisi luncike ngokunembile kulolu hlobo lwendlela.

Mayelana namapharamitha awusizo kakhulu lapho ucela i-YARA, izinketho ezinjengalezi ezilandelayo ziyagqama: -r ukusesha ngokuphindaphindiwe, -S ukubonisa izibalo, -m ukukhipha imethadatha, kanye -w ukuziba izixwayisoNgokuhlanganisa lawa mafulegi ungakwazi ukulungisa indlela yokuziphatha esimweni sakho: kusukela ekuhlaziyweni okusheshayo kumkhombandlela othize kuya ekuskeneni okuphelele kwesakhiwo sefolda eyinkimbinkimbi.

Imikhuba emihle kakhulu lapho ubhala futhi ugcina imithetho ye-YARA

Ukuze uvimbele inqolobane yakho yemithetho ekubeni isiphithiphithi esingalawuleki, kuyatuseka ukuthi usebenzise uchungechunge lwezinqubo ezihamba phambili. Okokuqala ukusebenza ngezifanekiso ezingaguquki kanye nezimiso zokuqamba amagamaukuze noma yimuphi umhlaziyi aqonde ukuthi umthetho ngamunye wenzani.

Amaqembu amaningi asebenzisa ifomethi evamile ehlanganisa unhlokweni onemethadatha, amathegi abonisa uhlobo lokusongela, umlingisi noma inkundla, kanye nencazelo ecacile yalokho okutholwayoLokhu kusiza hhayi ngaphakathi kuphela, kodwa nalapho wabelana ngemithetho nomphakathi noma unikela kumakhosombe omphakathi.

Esinye isincomo ukuthi uhlale ukukhumbula lokho I-YARA iyingqimba eyodwa nje yokuzivikelaAyithathi indawo yesofthiwe ye-antivirus noma i-EDR, kodwa kunalokho iyawaphelelisa ngamasu okuthi Vikela i-Windows PC yakhoNgokufanelekile, i-YARA kufanele ilingane nezinhlaka ezibanzi zereferensi, njengohlaka lwe-NIST, oluphinde lubhekane nokuhlonzwa kwempahla, ukuvikelwa, ukutholwa, ukusabela, nokutholwa.

Ngokombono wezobuchwepheshe, kufanelekile ukuzinikezela isikhathi evitar falsos positivosLokhu kuhilela ukugwema izintambo ezijwayelekile kakhulu, ukuhlanganisa izimo ezimbalwa, nokusebenzisa ama-opharetha afana nalawa all of o any of Sebenzisa ikhanda lakho futhi usebenzise izakhiwo zesakhiwo sefayela. Uma kucace kakhudlwana ukuqonda okuzungezile ukuziphatha kohlelo olungayilungele ikhompuyutha, kuba ngcono.

Okokugcina, gcina isiyalo se inguqulo nokubuyekezwa ngezikhathi ezithile Ibalulekile. Imindeni yohlelo olungayilungele ikhompuyutha iyashintsha, izinkomba ziyashintsha, futhi imithetho esebenzayo namuhla ingase ibe mfushane noma iphelelwe yisikhathi. Ukubuyekeza nokucwenga umthetho wakho osethiwe ngezikhathi ezithile kuyingxenye yomdlalo wekati negundane we-cybersecurity.

Umphakathi we-YARA nezinsiza ezitholakalayo

Esinye sezizathu eziyinhloko ukuthi i-YARA ize kuze kube manje amandla omphakathi wayo. Abacwaningi, amafemu okuvikela, namathimba okuphendula avela emhlabeni wonke abelana ngokuqhubekayo ngemithetho, izibonelo, kanye nemibhalo.ukudala i-ecosystem ecebile kakhulu.

Iphuzu eliyinhloko lokubhekisela kulo yi- Indawo esemthethweni ye-YARA ku-GitHubLapho uzothola izinguqulo zakamuva zethuluzi, ikhodi yomthombo, nezixhumanisi zokuya kumadokhumenti. Ukusuka lapho ungalandela ukuqhubeka kwephrojekthi, ubike izinkinga, noma unikele ngokuthuthukiswa uma uthanda.

Imibhalo esemthethweni, etholakala ezisekelweni ezifana ne-ReadTheDocs, iyanikezwa umhlahlandlela ophelele we-syntax, amamojula atholakalayo, izibonelo zemithetho, nezinkomba zokusebenzisaKuyisisetshenziswa esibalulekile sokuthatha ithuba lemisebenzi ethuthuke kakhulu, njengokuhlola i-PE, i-ELF, imithetho yenkumbulo, noma ukuhlanganiswa namanye amathuluzi.

Ngaphezu kwalokho, kukhona izinqolobane zomphakathi zemithetho ye-YARA namasignesha lapho abahlaziyi abavela kuwo wonke umhlaba Bashicilela amaqoqo alungele ukusetshenziswa noma amaqoqo angavunyelaniswa nezidingo zakho.Lawa makhosombe ngokuvamile ahlanganisa imithetho yemindeni ethile yohlelo olungayilungele ikhompuyutha, izinsiza zokuxhaphaza, amathuluzi okuhlola asetshenziswa kabi, amagobolondo ewebhu, ama-cryptominers, nokunye okuningi.

Ngokuhambisanayo, abakhiqizi abaningi namaqembu ocwaningo anikela Ukuqeqeshwa okukhethekile kwa-YARA, kusuka emazingeni ayisisekelo kuya ezifundweni ezithuthuke kakhulungokuvamile ngamalebhu abonakalayo kanye nokuzivocavoca okusekelwe kumacala omhlaba wangempela.
