如何在Windows 2003中得到登陆密码

作者: 来源: 添加时间:2006-5-23 18:45:23

  下面的代码使用的是很笨,而且很原始的搜索方法,主要是搜索Lsass内存中"LocalSystem Remote Procedure"这个字符串,因为在相当多的测试中,密码都是保存在有这个字符串的地址后一点的位置中,当然了,很多系统并没有这个字符串,或者就算有,我们得到的都是错误的密码。

  附件程序相当于密码定位程序,用来测试在lsass内存中搜索指定的字符串或模拟登陆的密码.

  用法:

  1.locator 字符串 -> 在lsass进程内存中搜索指定的那个"字符串",返回确定的位置

  2.Locator 用户名 密码 -> 在系统中建立一个参数指定的用户,并进行模拟登陆,然后搜索"密码"在lsass进程内存中的位置,生成的帐户程序运行完后会自动删除。
