說明:網上的朋友,大家好!
這是我寫的第二篇破解實戰,如若有紕漏,請各位大蝦多指教!
特別感謝看雪大蝦。是他編輯的破解教材《CRACK教學》,讓我在學習破解的過程中受益匪淺。
首先用Trw2000載入Offline Explorer
輸入註冊資訊
name:xiA Qin
&任意輸入
register key:1949101 &任意輸入
下指令bpx hmemcpy //下中斷點
按F5回到程式,按確定,這時會被Trw2000攔截到。
下指令bd * //屏障中斷點
下指令pmodule //直接跳到程式的領空
按F10來到下面指令
015F:004B8B1F MOV EAX,[EBP-04]
015F:004B8B22 PUSH EAX
015F:004B8B23 LEA EDX,[EBP-08]
015F:004B8B26 MOV EAX,[EBX+02E0]
015F:004B8B2C CALL 00432F2C
015F:004B8B31 MOV EDX,[EBP-08]
015F:004B8B34 MOV EAX,[004D8C4C]
015F:004B8B39 MOV EAX,[EAX]
015F:004B8B3B POP ECX
015F:004B8B3C CALL 004C65E0
->這個CALL有問題,按F8進入。
015F:004B8B41 TEST AL,AL
->檢驗註冊標記
015F:004B8B43 JZ 004B8BAA
->註冊碼不相等,就跳004B8BAA
015F:004B8B45 MOV EAX,[004D8C4C]
015F:004B8B4A MOV EAX,[EAX]
015F:004B8B4C MOV BYTE [EAX+060C],01
015F:004B8B53 LEA EDX,[EBP-04]
...............................
015F:004B8BAA PUSH BYTE +10
015F:004B8BAC LEA ECX,[EBP-10]
015F:004B8BAF MOV EAX,[004D8C4C]
015F:004B8BB4 MOV EAX,[EAX]
015F:004B8BB6 MOV EAX,[EAX+04F8]
015F:004B8BBC MOV EDX,07
015F:004B8BC1 CALL 004A4CB0
015F:004B8BC6 PUSH DWORD [EBP-10]
015F:004B8BC9 PUSH DWORD 004B8CA8
...................
015F:004B8C52 CALL 00404034
015F:004B8C57 MOV ECX,EAX
015F:004B8C59 MOV EDX,004B8CB8
015F:004B8C5E MOV EAX,[004D8E4C]
015F:004B8C63 MOV EAX,[EAX]
015F:004B8C65 CALL 0044F6D8
->到這裡GAME OVER了,
015F:004B8C6A XOR EAX,EAX
向上看什麼地方可以
015F:004B8C6C POP EDX
跳過這個CALL.
015F:004B8C6D POP ECX
=========================================
按F8進入004B8B3C CALL後
按F10來到下面的指令
015F:004C6930 FF75FC PUSH DWORD
[EBP-04]
015F:004C6933 681C6D4C00 PUSH DWORD 004C6D1C

015F:004C6955 E876FAFFFF CALL 004C63D0
015F:004C695A 8B55F0 MOV
EDX,[EBP-10] ->真正的註冊碼 下指令D EDX
015F:004C695D 8B45F8 MOV
EAX,[EBP-08] ->這裡是你輸入的註冊碼
015F:004C6960 E81BD6F3FF CALL 00403F80
