一个未完成的破解 (SubmitWolf Enterprise V4.02 CN build: 003 Script: 1.000)

时间:2004/10/15 1:02:00来源:本站整理作者:蓝点我要评论(0)

 软件的功能概述:
~~~~~~~~~~~~~~
    SubmitWolf是宣传因特网站点的自动提交向导,它能够在几分钟内将一个URL排列
到数百个搜索引擎和链接目录上。

保护方法:
~~~~~~~~
    简单的name/code保护;未注册版本中,大多数站点不可使用,URL只能被提交到少数
几个选定的站点。

破解过程:
~~~~~~~~
(第一次)    启动TRW2000,按OK,TRW2000已隐藏在TaskBar了。运行SubmitWolf,按“注册”,
            分别填入:

注册名称:iloveeagle
序列号:  10101010

CTRL-N,进入TRW2000,下断点bpx getdlgitemtexta,再CTRL-N,按“确定”。程序中断在:

走到:004185C0处,看看跳转的两个方向,都没要出对话框的意思。那么先F10跟它走,看看有何结果。我们来
到:00418637处。

走到这里,抬头看看eax,它的值为0。程序不会跳走,再看看下面的语句,将要显示一个出错对话框。我们

(第二次)    CTRL-N,回到程序,重新输入注册信息。这次CODE我输的是191919(为了便于进行内存搜索,我
            每次都输不同的CODE,这是个小经验)。CTRL-N进入TRW2000,在:0041859D处双击鼠标,设置断
            点。再CTRL-N回到程序,按下“确定”钮。(BC *)清除所有断点,F10一直到

(第三次)   这里我略去了一个繁长的计算过程。其实第二次我们不会来到这里,反而会很快跳到:00419209
           处,返回eax=0,跳到失败。从第二次的过程我们看到,注册码的前两位必须是“PY”或“EY”
           并且必须有一位是“-”。再从头来一次,这次输入name:QQQ/code:EY2000-121212。进入

           :0041865B E890090000              call 00418FF0
          
           后,反正是F10,一路按下。突然,看看下面,多么熟悉的身影映入眼帘。这样你就得到了一个
           正确的注册码组合。若想作注册机就仔细研究一下略去的部分。

事情完了吗?没有。我们应该研究一下两个标有(***)的程序段。第一个程序段在判断CODE中含有“R”
后,把NAME和CODE在内存的地址对调;第二个程序段是判断NAME中是否含有字符“@”。见下面总结:

总结:

这个程序存在两种类型的注册码:

1、一种注册码形式如:
Name:QQQ/code:EY2000-121212
    这里,"EY"和"-"间的数字随意。“-”后的数字由Name和“-”前的字符(包括EY)
算出。“EY”也可以是“PY”。当然"EY"和"-"间也可以没东西,这样注册后也可看到
注册成功的画面。但在联网升级时,会发生错误,连选择升级组件的列表都不出现;我
用上面的注册码注册时,会出现选择升级组件的列表,选好组件后,要求我输入email地
址,这时我才犯难了。我怎么知道有哪些email地址在它的服务器上注了册,我又不是
黑客。

2、另一种注册码形式如:
Name:anything@anything/code:EYR2002-121212
    这种形式的注册码和NAME是无关的。注册码中必须含有“R”,前两位也必须是
“EY”或“PY”。“-”后的数字由字符“EPAK”和“-”前的字符(包括“EY”或“PY”)
算出。而NAME中的“@”是必须有的,作者很可能想让你输入email地址。这种注册码也许和
引擎软件包(Engine Pack)的升级有关。
