商务精灵 V1.22 Build 2003.04.18 时间：2004/10/15 0:57:00来源：本站整理作者：蓝点我要评论(0): 　（1）破解：mwd[DFCG]
（2）目的:找出算法 ,作出注册机。
（3）练习程序: 商务精灵 V1.22 Build 2003.04.18
（4）难度：简单，明码。
（4）下载： http://www.skycn.com/soft/8146.html
（5）工具:Ollydbg,PW32Dasm.PEiD，pe-scan。
（6）开始：PEiD检查程序带ASPack 2.12 -> Alexey Solodovnikov的壳，pe-scan脱壳，
PW32Dasm载入程序找到相关信息，OLL载入程序过程如下：输入注册信息：注册名；DFCG
注册码：121212。
这软件竞然卖120大元~！！！
