Swivutiso Leswi Vutisiwaka Nkarhi Na Nkarhi

I yini xifaniso xa makete wa switoko xa 1986 lexi nga endliwa hi ndlela yo tlhelela endzhaku?

Xifaniso xo sungula a ku ri xiphemu xa software xa vuphayona ku sukela hi 1986 lexi a xi modela mahanyelo ya makete wa switoko hi ku tirhisa tialgorithm leti nga emahlweni hi ndlela yo hlamarisa eka nguva ya yona. Eka malembe manharhu ya vuinjhiniyere byo tlherisela endzhaku hi vukheta, muendli u decode logic ya yena ya vulawuri, a paluxa ndlela leyi vaendli va tiprogreme vo sungula va tshinelelaka ku tekelela makete hi switirhisiwa leswi nga nyawuriki swa khomphyuta. Phurojeke yi kombisa hilaha milawu ya vunjhiniyara bya software ya khale ya ha khomeke nkoka hakona eka ku endliwa ka xikombiso xa timali xa manguva lawa na dizayini ya mintlangu.

Ha yini munhu a nga heta malembe manharhu a ri karhi a reverse-engineering software ya khale?

Sofwere ya ndzhaka ya vunjhiniyara byo tlherisela endzhaku yi hlayisa matimu ya xidijitali na ku paluxa tithekiniki leti rivariweke. Eka mhaka leyi, simulator ya 1986 a yi ri na ti algorithms to hlawuleka ta makete-modeling leti nga si tshamaka ti tsariwa erivaleni. Ku twisisa maendlelo lawa swi nyika vutivi eka timali ta xibalo ta le ku sunguleni. Eka vatumbuluxi na vatumbuluxi lava tekelaka enhlokweni ku dyondza ku suka eka nkarhi lowu hundzeke, tipulatifomo to fana na Mewayz ti nyika mfikelelo eka ku tlula 207 wa mimojula leyi hlayisiweke hi $19/mo ntsena, ku ku pfuna ku aka eka masungulo lama tiyisisiweke ku tlula ku sungula ku suka eka xiyimo xa le hansi.

Hi yihi mintlhontlho ya xithekiniki leyi katsekaka eka ku tlherisela endzhaku vunjhiniyara bya nongonoko wa malembe ya 40?

Mintlhontlho leyikulu yi katsa ku tirha na ti-architecture ta hardware leti nga ha tirhisiwiki, khodi ya muchini leyi nga riki na maphepha, na ti toolchains ta nhluvukiso leti lahlekeke. Muendli wa yona a a fanele a hlamusela swiletelo swa nhlengeletano leyi nga si swekiwaka, a pfuxeta swivumbeko swa data handle ka khodi ya xihlovo, ni ku endla mepe wa ku khuluka ka phurogireme eka magidi ya maendlelo. Tindhawu ta ku tekelela a ti ri ta nkoka eka ku kambela tihypothesis. Ntirho wun’wana na wun’wana lowu decoded a wu lava ku cross-referencing mahanyelo lama xiyiweke na disassembled code — endlelo ro tika leri lavaka ku lehisa mbilu na vutshila byo enta bya xiyimo xa tisisiteme.

Ndzi nga sungula njhani ku aka kumbe ku lavisisa tiphurojeke ta xithekiniki to fana na leyi?

Sungulani hi ku dyondza masungulo — vumaki bya khompyuta, ririmi ro hlengeleta, na switirhisiwa swa vuinjhiniyere byo tlhelela endzhaku ku fana na Ghidra kumbe IDA. Hlanganyela na miganga ya xihlovo lexi pfulekeke laha tiphurojeke ta ntirhisano ti humelelaka. Loko u lava ku hatlisisa ku dyondza ka wena eka tidyondzo to tala, Mewayz yi nyika mimojula ya 207 leyi katsaka tinhlokomhaka ta nhluvukiso, dizayini, na xithekiniki hi $19/mo, yi ku nyika ndlela leyi hlelekeke yo ndlandlamuxa vuswikoti bya wena na ku langutana na tiphurojeke leti nga na xikongomelo hi ku titshemba.
