1. Cov Ntsiab Lus Tseem Ceeb
1.1 Confusion: Ntau tus neeg xav tias thaum ua tus yuam sij rau lub intercom, tus tswv sau ib yam dab tsi rau tus yuam sij rau tus yuam sij rau tus yuam sij rau tus yuam sij rau tus yuam sij rau tus yuam sij no tuaj yeem qhib lub intercom. Nyob rau tib lub sijhawm, liam, nrog lwm qhov kev sib nkag siab, tus yuam sij no tsis tuaj yeem ua haujlwm.
1.2 Qhov tseeb, nyob rau hauv lub inwhooming feem ntau ntawm intercom tshuab, tsis muaj kev hloov pauv yog ua rau tus yuam sij. Cov ntaub ntawv sau tseg yog ua rau lub cim xeeb ntawm intercom, thiab tshwj xeeb - tus lej tseem ceeb yog sau rau nws hauv kev tsim khoom ntawm nws. Ntawm chav kawm, cov cai no tuaj yeem raug sau ua ib qho tsis muaj peev xwm ntawm cov neeg coob coob tau tshaj tawm nrog tus yuam sij no, thiab lawv yuav coj nws ua ib txwm muaj.
1.3 Kev Zam: Mifare hom yuam sij. Ntxiv nrog rau lub Hoobkas code, tus yuam sij ntawm hom no muaj ib cheeb tsam nco zoo li cas. Nyob rau hauv xws li ib tug yuam kev tus yuam sij, cov ntaub ntawv raug tsim ua - ib tus password tshwj xeeb nrog nkag mus rau hauv lub cim xeeb tseem ceeb. Thaum cloning (saib hauv qab), tsuas yog lub Hoobkas code yog theej, tab sis tsis yog tus password. Raws li qhov tshwm sim, lub clone ntawm xws tus tseem ceeb yuav tsis lees paub los ntawm Intercom, raws li "raws li daim ntawv hla tebchaws" zoo li nws tus kheej, thiab tus password tsis paub.
1.4 Sau cov yuam sij thiab sau cov yuam sij. Ntawm no kuv thov kom tsis txhob tsis meej pem. Muaj cov yuam sij nrog cov pab pawg sib txuas ua ke hauv lub Hoobkas code, thiab muaj cov yuam sij enterproof, thiaj li hu ua. "Dawdks". Lawv tsis muaj txoj cai hauv lawv tus kheej thiab yog tsim tshwj xeeb kom luam cov cai ntawm ib tus yuam sij uas twb muaj lawm ntawm cov keyboard.
Tab sis cov ntaubntawv povthawj ntawm cov ntaub ntawv tsis yog ua los ntawm tus tswv ua koj lub intercom, tab sis "txiv ntxawm Ast" hauv cov ntaub ntawv tseem ceeb siv cov ntawv tshwj xeeb uas txhawb ntau tus lej sau. Nyob rau hauv txhua rooj plaub, tsuas yog ib txoj cai tuaj yeem sau cia rau ib zaug hauv qhov kev ua haujlwm no. Koj tsis tuaj yeem tso cov cim ntawm ob tus yuam sij sib txawv rau ib qho seem!
Tom qab luam cov cai hauv lub cim xeeb ntawm cov haujlwm ua haujlwm, tus clone tau txais txoj cai ntawm cov khoom tseem ceeb nrog qee qhov kev txwv:
Qee cov intercoms tau nruab nrog cov lim dej anticlon, yog li xyeej cov duplicates ntawm cov yuam sij ntawm cov yuam sij.
Koj tsis tuaj yeem luam cov ntsiab lus ntawm Mifare qhov tseem ceeb, uas tau hais los saum toj no.
2. Dab neeg ntawm cov lus cim tseg "tagnrho
Tsim kom muaj lub universal yuam sij ntawm qee qhov kev txwv yog qhov ua tau. Tab sis kuv yuav hais tam sim ntawd, tsis muaj qhov tseem ceeb ntawm unenalal kiag li, yog tias tsuas yog tsis muaj ib qho tseem ceeb rau kom tau txais cov yuam sij universal:
2.1 Txoj Kev Ncaj Ncees Ncaj Ncees - mus rau npe tus yuam sij rau txhua tus muaj nyob hauv zej zog. Piv txwv li, kev sib tham sib pab ua rau ntau tus yuam sij rau cov tuam txhab ua haujlwm hauv cheeb tsam, thiab cov khoom siv tau tshiab rau txhua qhov haujlwm hauv nroog. Txhua zaus ib qho luam no yog ntxiv rau cov intercom tshiab, tag nrho cov counterparts ntawm tus yuam sij no "hauv kev nkag mus rau lub nkag tshiab. Cov ntawv luam ntawm cov ntsiab lus xws li tau faib los ntawm cov neeg xa ntawv, cov nqi hluav taws xob thiab, tau kawg, tub ceev xwm. Xav txog? Cov yuam sij tau muab faib rau, thiab kev hloov tshiab txuas ntxiv! Txawm li cas los xij, nyob rau hauv no moth barrel muaj ib khub ntawm xav tsis thoob:
▶ Lub ntsiab lus tseem ceeb ntau yam ntawm hom qauv. Qee cov kev ua haujlwm tau ua haujlwm nrog kev sib cuag "ntsiav tshuaj" ntawm ntau yam, lwm tus - nrog cov khoom sib tiv tauj.
▶ lim lim ntau ntau yam intercal thiab cov tricks uas tsis tso cai siv cov ntawv theej tawm.
2.2 emulator - ib lub cuab yeej nrog cov zaub thiab lub cim xeeb hauv cov lej tseem ceeb tau theej nrog nkag mus rau kev sib txawv. Txhua qhov chaws muab rau cov lus hais (ntaus "3rd cov neeg txhim kho txoj kev, lub tsev 25, uas tso cai rau koj kom pom cov cai xav tau hauv kev nco ua ntej thov kom tus nyeem ntawv. Lub ntsiab kom zoo dua ntawm emulator muaj peev xwm qog cov yuam sij ntawm ntau hom: ob qho tib si dallas, thiab metakom, thiab ntuj raug txim hauv ib kauj ruam.
2.3 Npaj nrog txoj cai tshwj xeeb. Cov taub hau ntse pom tias unoccupied intercterter cig yog muaj lej 255 (FF hauv 16-Rice system). Cov naj npawb no yog tus cim ntawm lub xov tooj nco dawb. Raws li qhov tshwm sim, nrog kev pab ntawm duplicator, cov yuam sij nrog cov code ntawm lub qhov rooj "DAWB" tau tsim, cov txiaj ntsig hauv txhua qhov intercom yam tsawg kawg yog ib qho kev cai tshiab , no Libhon tau tshem tawm, tab sis txog xyoo 2005, qhov kev ua yuam kev ua haujlwm txhua txhia qhov chaw.
3. Lub tswvyim ntawm cov yuam sij demagnetic
3.1 Moorthood: Cov yuam sij ntawm Domofon yog yuam kev hu ua "magnitics" lossis "sib nqus yuam sij". Raws li, cov neeg ntshai tias nyob rau hauv kev ua ntawm cov hlau nplaum, tus yuam sij tuaj yeem muab tso cia, vim tias lub qhov rooj yuav nres qhib.
3.2 Qhov tseeb, "ntsiav tshuaj", thiab tsis muaj kev sib cuag tseem ceeb ib zaug yog tsis pom zoo rau cov hlau nplaum. Tus kws sau ntawv tau sim ua cov yuam sij uas tsis zoo nrog lub zog neodymium haib, tab sis lawv tsis yog lo rau nws! Tom qab cov hlau nplaum yog qhov cuam tshuam, cov yuam sij tau khaws cia ua tau zoo.
3.3 Qhov tseeb tsis ntseeg ces? Nyob rau ib lub sijhawm, cov yuam sij sib nqus tau siv hauv kev nkag mus tswj cov tshuab. Thiab tam sim no nkag mus rau qee lub tsev txhab nyiaj tau ua kom tiav los ntawm daim ntawv qhia chaw txhab nyiaj sib nqus. Los ntawm txoj kev, koj tuaj yeem txhais lub txhab nyiaj sib nqus daim npav.
+ Cov yuam sij feem ntau swb. "Cov ntsiav tshuaj", piv txwv li, tuag los ntawm kev rho tawm ntawm cov kab mob zoo li qub. Yog tias peb muaj daim npav tiv toj nyob hauv lub hnab tshos tom qab, tom qab ntawd zaum ib txwm yuav nqa daim npav mus rau lub xeev cracked thiab nws yuav nres ua haujlwm. Feem ntau cov feem ntau, nws yog qhov tseeb no aws thiab yog hu ua "demagnetization." Thaum tus yuam sij tawm ntawm qhov kev txiav txim nqa tau cov txheej txheem lossis cov thawj coj, nws tsis "enchain" nws, tab sis muab ib qho tshiab.
+ Cov yuam sij tiv tauj ntawm hom "ntsiav tshuaj" los ntawm kev siv nquag tau nyob hauv tus tuav thiab nres tiv toj tus nyeem ntawv. Ntawm no, ib yam nkaus, tseem muaj kuj tseem muaj lus hais txog Demagnetization. Cia li muag ib ntsiav tshuaj nyob rau hauv kev coj rov qab ↓
