# 基本信息
**WHOIS**协议作为一种标准方法,通过特定数据库查询各种互联网资源的**注册者或持有者**。这些资源包括域名、IP地址块和自治系统等。除此之外该协议还应用于访问更广泛的信息。
**默认端口:**43
```
PORT STATE SERVICE
43/tcp open whois?
```
# 枚举
获取 whois 服务对域名的所有信息:
```bash
whois -h <HOST> -p <PORT> "domain.tld"
echo "domain.ltd" | nc -vn <HOST> <PORT>
```
注意有时在向WHOIS服务请求某些信息时响应中会出现正在使用的数据库
![](<../.gitbook/assets/image (147).png>)
此外WHOIS服务始终需要使用**数据库**来存储和提取信息。因此,当从用户提供的信息**查询**数据库时,可能会存在**SQL注入**。例如,执行`whois -h 10.10.10.155 -p 43 "a') or 1=1#"`,您可能能够**提取**数据库中保存的所有**信息**。
