SWF探索者(SWFExplorer)XP V1.11.2002.326 破解过程
破解撰写：leeyam[BCG]
运行该程序，随意输入注册信息，提示需要重新启动软件验证注册码。
判断该程序先将输入的注册码存放某个位置，然后启动时调用！
用Language发现是用PECompact加的壳，用UnPECompact自动脱壳。再用PEditor载入脱壳后的程序，选择"sections"修改Pec1为.data。然后利用W32Dasm反编，查找字串，发现程序会调用注册表，双击进入第一个调入：

:004B4E31 8B55E4 mov edx, dword ptr [ebp-1C]…………………………调入真码
:004B4E34 A1ECED4B00 mov eax, dword ptr [004BEDEC]…………………………调入假码

:004B4E3E 0F9405E0ED4B00 sete byte ptr [004BEDE0]
看到这里眼前一亮，发现上面004B4E39的Call可疑，于是开始用TRW2000直接下中断bpx 4b4e39 顺利拦截，D edx 看见真码。 |
