信息收集是渗透前期最为重要的一步，其中被动信息收集相对主动信息收集（访问）更具有隐蔽和无害性。便于进行社工攻击。
被动信息收集主要特点
公开渠道可获得的信息
与目标系统不产生直接交互
尽量避免留下一切痕迹
主要归纳应用收集信息
信息收集的内容有很多，简略其下：
- IP地址段
- 域名信息
- 邮件地址
- ⽂档图⽚数据
- 公司地址
- 公司组织架构
- 联系电话 / 传真号码
- ⼈员姓名 / 职务
- 目标系统使⽤的技术架构
- 公开的商业信息
1.信息收集-DNS
域名记录：
- A: 主机记录，他会把一个域名解析到ip地址上
- Cname : 别名记录，他会把一个域名解析到另外一个域名上
- NS ：这个域的域名服务器的地址记录
- MX: 邮件交换记录，它会指向这个域的SMTP交换记录
- ptr :反向解析，把ip 解析成域名的
完整的： www.baidu.com.
首次解析查询会进行迭代查询，先查（全球13台）根域服务器.-->com服务器 baidu.com. -->baidu.com的域名服务器找到：www.baidu.com.
我们运营商的DNS服务器是缓存服务器。这样把上面首次的ip与域名的对应记录本地DNS服务器会保存一份，后续就直接拿来直接用，即递归查询。
1.1 DNS信息收集-NSLOOKUP的使用
• nslookup www.sina.com • server //指定dns服务器查询 • type=a、mx、ns、any //指定查询类型；any是全部 • nslookup -type=ns example.com 156.154.70.22 //一句命令行查询
