0x000 简介
K8Cscan扫描器Python版支持Windows和Linux系统
详情参考：https://www.cnblogs.com/k8gege/p/10519321.html
0x001 功能
1.MS17-010漏洞检测
2.SMB协议版本探测
3.存活主机扫描
4.DLL插件扫描(可加载Cscan已发布的DLL，注：该功能仅限Windows且.net版本>=4.0)
PS:由于Cscan功能较多，发现Py可调用.net编写的DLL，偷懒先加载现有插件。
虽然思路一样，但有些功能实现起来不一样，比方其它语言均可ICMP协议实现ping
当然python也可以，但是Py的Socket Raw一定要管理员权限，为了保证任意权限下可用
所以PY版我采用调用系统ping命令这种非常次的方法，来实现内网存活主机的扫描。
没办法我们不是那种可以扛自己的设备去现场接条网线施工的人，打下的权限未必高权限。
很多时候同样的功能由于实现方式不一样，有些工具任意权限下可用，有些仅管理员可用。

0x003 用法
例子1: SMB漏洞之MS17-010扫描
例子2：DLL扫描之Cscan操作系统探测插件
根目录下放osscan.rar中的netscan40.dll即可（其它dll同理,windows下不建议python版）PY受好者请继续
如图所示探测到内网Win7三台、Win10两台、2012一台及主机名、路由一台（开放WEB服务，产品版本等）
例子3：SMB版本探测(可用于判断操作系统，因Linux默认不开启)
SMB版本对应操作系统(可用于判断操作系统，因Linux默认不开启)
Scan Smb Version 192.11.22.118 SMBv3.0 Win8.1 192.11.22.7 SMBv3.0 Win10 192.11.22.41 SMBv2.1 (Win7) SMBv1 XP or 2003 Kali开启SMB后 192.11.22.54 SMBv3.0 192.11.22.54 KALI [Win 6.1] 抓包显示为 Windows Server 2003 3790 Service Pack 2
例子4：Kali下使用
