【文章标题】: “系统优化大师”的破解
【文章作者】: Mr.vit
【下载地址】: 自己搜索下载
【加壳方式】: ASPack v2.12 -> Alexey Solodovnikov
【使用工具】: OD C32ASM
【操作平台】: xp sp2
【作者声明】: 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】
不脱壳,直接用OD载入程序,F9运行程序,ALT+E,打开可执行模块窗口,选择程序的主线程,双击
00401000 04 10 add al,10
00401002 40 inc eax
00401003 0003 add byte ptr ds:[ebx],al
00401005 07 pop es
00401006 42 inc edx
00401007 6F outs dx,dword ptr es:[edi]
00401008 6F outs dx,dword ptr es:[edi]
00401009 6C ins byte ptr es:[edi],dx
0040100A 65:61 popad
0040100C 6E outs dx,byte ptr es:[edi]
再搜索一下字符串,就一句吧“注册信息没有填写齐全”,双击进去,再找到段首

其实这个软件注册码是很好找的
看到 0054E6FB BA 90E85400 mov edx,yhds.0054E890 ; yhdtn.dll
这里是有一个yhdtn.dll的文件,也就是说注册成功以后,就会产生这一个DLL文件,在程序的目录下面的
单步跟踪后,找到注册码,然后关闭OD
打开系统优化大师,把刚才的确认码与注册码填进去,提示会注册成功
我填写的确认码为:123
注册码为:3436k5w126~f3641
这样程序就注册好了
去程序根目录下看一下,这时会多出一个yhdtn.dll,难道这就是一个注册文件???
用C32ASM打开看,显示内容为
01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 01
因为我影子系统开启了,所以重启计算机,刚才装的优化大师就还原了。
所以再装一下优化大师,把yhdtn.dll拷到程序目录,打开程序,点击关系软件,提示授权为已注册,到这里我就确写,这是一个
注册文件了
做绿色软件的话可以把这个文件集成一下,也不用什么注册码,确认码了,哈哈
