Cov qauv siv ua qauv qhia yog muab los ntawm cov tuam ntxhab kom paub zoo dua nrog lawv cov khoom. Raws li txoj cai, tom qab xaus lub sijhawm sim, qhov kev zov me nyuam tsis ua haujlwm thiab yuav tsum tau nkag tus lej tseem ceeb lossis them nyiaj hauv Is Taws Nem.
Cov Lus Qhia
Kauj ruam 1
Nws yuav tsum nkag siab tias tom qab qhov kawg ntawm lub sijhawm sim ntawm qhov kev zov me nyuam, tsuas yog txoj kev xaiv kom them nyiaj rau nws txoj kev siv txuas ntxiv. Txawm li cas los xij, tus nqi uas cov tuam txhab tsim tawm rau lawv cov kev pab cuam qee zaum siab heev thiab tsis muaj peev xwm tshaj tawm rau cov neeg muaj nyiaj tsawg. Ib qho ntxiv, ntau tus neeg siv tsis xav tau cov kev pabcuam rau kev siv tus kws tshaj lij, tabsis rau kev ua haujlwm ib zaug ua qee txoj haujlwm. Coj qhov no mus rau hauv tus account, lo lus nug tshwm sim ntawm yuav ua li cas ncua lub sijhawm sim ntawm qhov kev zov me nyuam lossis yuav ua li cas nres lub sijhawm taug qab nrog qhov demo version.

Yog tias qhov demo version ntawm qhov kev zov me nyuam koj siv tau ua tiav kev ua haujlwm, tab sis tsis ua haujlwm tom qab qee lub sijhawm, qhov kev xaiv yooj yim tshaj plaws yog tshem tawm cov program hauv koj lub computer thiab rov nruab nws. Hauv qhov no, koj yuav tau txais dua los ua haujlwm thaum lub sijhawm sim. Txhawm rau tshem tawm demos, siv Uninstall Tool, uas tshem tag nrho cov kab ntawm qhov kev pab cuam nruab ntawm koj lub computer.

Yog tias qhov kev rov xaiv dua tshiab tsis haum koj lossis qhov demo version ntawm qhov kev pabcuam tsis muaj txhua txoj kev tuaj yeem, koj tuaj yeem sim nres qhov kev sim mus kuaj koj tus kheej. Xav txog ib qho tseem ceeb: tsis muaj leej twg muaj cai los tiv thaiv koj ntawm kev tshawb fawb cov haujlwm. Tab sis yog tias koj muab tso ib qho kev nyiag nkas hauv lub network rau kev siv rau pej xeem, ces qhov no twb tau ua txhaum kev ncaj ncees rau cov cai no nrog txhua qhov yuav tshwm sim los ntawm qhov tseeb no.

Txhawm rau tshawb xyuas cov haujlwm, siv cov khoom siv tshwj xeeb. Ua ntej, PEID, yuav qhia koj tias qhov program sau dab tsi lossis sau dab tsi lub thawv ntim nrog. Nyob rau hauv rooj plaub tom kawg, qhov kev zov me nyuam yuav tsum tau nrawm siv cov txheej txheem tsis tsim nyog. Piv txwv, yog tias ib qho kev pab cuam raug ntim siv UPX, ces nws yuav tsum tsis tau ntim nrog cov kev siv tsim nyog - piv txwv li, Unpacker rau UPX. Thov nco ntsoov tias qhov kev zov me nyuam tuaj yeem tiv thaiv tau ntxiv ib tus cryptor, uas tseem yuav tau muab tshem tawm.

Tom qab tsis tsim nyog, qhov kev zov me nyuam yuav tsum tau qhib hauv qhov debugger - qhov kev pabcuam tshwj xeeb uas tso cai rau koj ua haujlwm nrog cov cai tswjfwm kev lag luam. Qhov yooj yim thiab yooj yim debugger yog Ole Debugger. Muaj cov ntawv Lavxias-lus Lavxias ntawm nws, tab sis nws zoo dua los siv cov lus Askiv qub, txij li ntau phau ntawv qhia txog yuav ua li cas nrog nws ua haujlwm. Rub tawm qhov program thiab nws cov plugins (xav tau), yog tsis muaj lawv lub debugger yuav tsis muaj tag nrho cov haujlwm tsim nyog.

Cov txheej txheem tiag tiag rau kev tshem tawm cov kev sim tawm zoo li qhov no. Thaum qhov kev zov me nyuam nyob rau hauv kev tshawb nrhiav pib, nws kuaj xyuas seb puas pom tus yuam pib nkag mus hauv. Yog tias muaj tus yuam sij, qhov dhia tau raws cai (yog tias muaj tus yuam sij, tom qab ntawd …) hloov kev tswj mus rau ib ntu ntawm cov code uas tso tawm qhov kev ua haujlwm puv ntawm qhov kev zov me nyuam, thiab tsis muaj lub ceeb toom qhia pom.

Yog tias tus yuam sij tsis pom, lwm qhov xwm txheej tau ntsib thiab hloov mus rau lwm ntu ntawm qhov chaws tshwm sim, qhov chaw ceeb toom ceeb toom qhia rau tus neeg siv. Txhawm rau tshem tawm kev sim tawm, koj yuav tsum hloov cov kev cai dhia mus rau qhov chaw ua haujlwm ntawm tus lej nrog qhov tsis muaj qhov tshwj xeeb - uas yog, ncaj qha. Qhov no tuaj yeem ua ncaj qha ib ntus hauv lub debugger. Tom qab ua kom paub tseeb tias txhua yam ua haujlwm thiab qhov program tsis muaj lus ceeb toom ntxiv, koj yuav tsum nco ntsoov ntu ntu kev hloov pauv (hauv hexadecimal encoding) thiab qhov qub - qhov ntawd yog, ib qho uas ua ntej qhov kev hloov pauv.
Kauj ruam 8
Theem kawg: cov kev pabcuam qub tau qhib nyob rau hauv tus lej code tus lej 60, qhov chaw uas tsis raug cai cov cim dhia tau pom los ntawm kev tshawb, uas yog yuav hloov nrog cov cim dhia tsis raug cai. Hloov pauv tau, hloov tau txais kev cawmdim. Cov phiaj xwm tiav tuaj yeem rov ua dua kom txo nws qhov loj.
