我担心你看错了方向，问题不在下载本身。

I fear you are looking in the wrong direction, the problem is not in the download itself.

你应该首先保护自己的网站。

- 强密码。

- 检查黑客是否有机器人创建新用户。

- 确保您的网站页面不包含安全漏洞。

You should rather start by securing your site itself.
- Strong passwords.
- Check that hackers have bot created new users.
- Make sure your site pages don't contain security holes.
