win下实现切换帐号的方法

by:dumplogin https://www.xfocus.net/

目前实现的方法有几种:
1.CreateProcessWithLogonW() //需要密码
2.LogonUser(),CreateProcessAsUser() //也需要密码
3.NtCreateToken(),CreateProcessAsUser() //不需要密码

1,2外面都有很多工具. 3的话bingle的wsu -f可以实现.
不过bingle的wsu只是做了SID的处理, 他切换到guest后,该环境下依然对system32目录有写权限.切换到SYSTEM后,对sam键还是打不开.
根据bingle的wsu原形,重写了一下SU, 可以真正做到权限切换,即使帐号被禁止
缺点是在终端下只能su到admin组和SYSTEM帐号.不能切换到普通用户,这个问题我是放弃了, 如果谁可以做到欢迎帮我完善.

搞这个东西搞的我疲惫不堪. 苦啊. 将我的代码贴出来,希望以后对大家有所帮助, 少走弯路.

在这个期间易做图扰bingle和tk n次,谢谢他们。

这个东东目前只在win2k sp4 cn上测试过, xp/2003缺少环境, 希望有人能帮我测试. :)

附:su4.c

/* su切换用户
* 2004/12/28 1.0,发现Bingle的wsu是假冒令牌,权限并没有真正设置.
* 2004/12/29 2.0,真正实现模拟用户令牌的动作.
* 2004/12/29 3.0,即使帐号禁止也可以模拟用户
* 2004/12/30 4.0, 可以模拟SYSTEM用户,权限24个,全部默认开放
* 2004/12/30 4.1 终端登陆用户可以获取管理员组/SYSTEM权限.普通用户失败.
