通过NPC名称找NPC数组

扫描 NPC名字  ASIC型

发现全部都有后缀

那么采用 字节集的方式去扫描

也是扫不到

说明:不是ASIC型字符串

扫描 NPC名字  Unicode型

没有结果

那么转换成字节集去扫描

终于发现结果了

把结果挨个修改字符串

 

发现   其中两个是可以用的     22和23    分别是人物头顶字符串和血条字符串

那么都可以使用

对名称下访问断

7692D335 >  8BFF            mov     edi, edi

7692D337    55              push    ebp

7692D338    8BEC            mov     ebp, esp

7692D33A    8B45 08         mov     eax, dword ptr [ebp+8]

7692D33D    66:8B08         mov     cx, word ptr [eax]               ; eax

7692D340    40              inc     eax

7692D341    40              inc     eax

7692D342    66:85C9         test    cx, cx

7692D345  ^ 75 F6           jnz     short 7692D33D

7692D347    2B45 08         sub     eax, dword ptr [ebp+8]

7692D34A    D1F8            sar     eax, 1

7692D34C    48              dec     eax

7692D34D    5D              pop     ebp

7692D34E    C3              retn

 

断到非游戏领空 ，并且该位置下断即断，其实是系统模块,所有字符串都会进行访问

那么我们只能通过堆栈跳回游戏领空

在断下的情况堆栈搜索 字符串指针   CTRL+L找到字符串最早出现的位置

来源某层CALL 的第一个参数

追第一个参数EAX即可

其中  [ebp+318]并非参数

分析ebp发现   其不是堆栈地址，那么318只是一个正常偏移而已

 

 

追到这里 我们需要进CALL 找EAX 的来源

但是 CALL里有很多代码  和跳转  那么我们需要 F7 走一遍 知道 CALL里面的跳转是怎么执行的

然后再-号逆向追寄存器即可
