【文章标题】: VB Decompiler 暴破 VB P-Code 某背单词软件
【软件名称】: 某背单词软件
【软件大小】: 1.14 MB
【下载地址】: 自己搜索下载
【加壳方式】: UPX 0.80 - 0.84 -> Markus & Laszlo
【保护方式】: 壳；字符串加密，注册信息存放加密数据库中
【编写语言】: Microsoft Visual Basic 5.0 / 6.0 (P-code)
【使用工具】: FFI，SmartCheck，VB Decompiler V5.0，WKTVBDE(只用到Help文件)
【操作平台】: Win32
【软件介绍】: 使用全新记忆理念精心打造的一款高效速记背单词软件
【作者声明】: 菜鸟一个，只是感兴趣，没有其他目的。失误之处敬请诸位大侠赐教!
--------------------------------------------------------------------------------
【详细过程】
File Format Identifier (FFI) v1.4 检测为：UPX 0.80 - 0.84 -> Markus & Laszlo
直接 Unpack 得到的 .EXE 大小为：3.49 MB
FFI v1.4 再次检测为：Microsoft Visual Basic 5.0 / 6.0
VB Decompiler V7.6 无法正常反编译，改用 VB Decompiler V 5.0 (gold7n) 修改版 能正常反编译
SmartCheck 加载，大致了解下程序的运行过程，直接在 VB Decompiler 中定位可疑关键点。

或二进制编辑工具修改。这里直接用 VB Decompile 的 Patch data 功能直接修改
[Tools] -> [Patch data] 填入Virtual Address: 62DF6B ,[Get] ,Data:00 5D <FB> 2F 3C
不对!?? 修改的应为 2F ，于是将 Virtual Address 改为: 62DF6C
[Get] ,Data: 5D FB <2F> 3C FF ，2F 改为 3C [Set] [Close]
试运行软件,没有啦烦人的随机提示注册，单词数量限制等也没有啦
帮助菜单显示 "本软件已经授权并激活！"
没有精力分析注册算法了，大概看了下应该注册信息是保存在加密的 .MDB 数据库里。
【经验总结】
软件的所有字符串都作了加密处理，但在 SmartCheck 下完全暴露，没有强的干扰作用
注册判断过程最终只用了 1 处判断，有6处调用注册判断过程，包括用 timer 检查
和各功能限制时检查，但关键处被找到就全军覆没！！！
Visual Basic P-Code 可以直接用 VB Decompile 快速打补丁!
“EqVar” 可改为 “NeVar” 外也可以改为 “LeVar”
VB Decompiler 的 “Decompile to source” 更方便阅读理解程序，
而 “Decompile to mnemonics” 就方便修改、打补丁！
