我的服务器是不是被人盯上了？

[hhhhhh123]

我刚刚发现 nginx 日志里面 有个 ip 疯狂在访问，这是为啥， 其实平常也是有很多不同的 ip 会访问，但是没在意。 虽然不知为啥，，然后我的网站还没弄好 域名都还没申请。很好奇他们是在干嘛？都是国外的 ip 因为我的服务器是亚马逊的。 这是一部分 IP

@hhhhhh123 你仔细看路径，都是扫描的 php 文件，发 get ，判断文件是否存在。phpinfo.php 是攻击者经常使用的探针，攻击者利用网站漏洞，写入 phpinfo 文件，通过访问这个文件可以看到服务器的 php 配置信息。

你要自己测试的话，可以搭建一个 php 环境，写一个 phpinfo.php ，内容为<?php phpinfo(); ?>，访问该文件，就能看到服务器的详细配置了。

攻击者通过访问该探针，获取服务器的更多信息，找到有漏洞的组件进行进一步的攻击。

当然，对于网站后门，攻击者也喜欢写成 phpinfo.php 。

日志中，只是单纯的判断这些后门文件是否存在，所以可以初步断定为是云运营商安全组件的扫描。

如果是攻击者的扫描行为，路径中会包含攻击代码。比如 SQL 注入会有 and 1=1 或者是 and 1=2 之类的关键字，XSS 攻击会有<script>或者是</script>关键字。

@eason1874 已经在学习 nginx 语法了， 准备屏蔽了

[hhhhhh123]

@onice 很好奇，都说要防止 sql 注入， 我在想 这种 sql 入侵都是什么情况下会发生？ 想不到场景

[onice]

@hhhhhh123 SQL 注入发生在用户的输入和数据库有交互的地方。比如查询商品信息。url 可能如下： https://xx.com/goods?id=1 ，id 参数是商品编号。用户传入不同的编号，页面上可以显示不同的商品信息。

对于不怀好意的用户(攻击者)，他们不会老老实实的只传编号，而是尝试传入攻击语句。由于编号会作为查询条件带入 sql 交予数据库去执行，所以把编号换成攻击语句，数据库也会执行攻击语句。这样就达到攻击的效果了。

只要是用户输入的东西，和数据库有交互的功能，而开发者也没有对用户传入的参数进行过滤和处理，都可能存在 SQL 注入漏洞。

SQL 注入漏洞的核心是通过用户的输入，控制原有的 sql 语句，达到攻击的效果。所以 sql 能做的事情，sql 注入都能做。这就是 SQL 注入的危害。

轻则泄露管理员用户和密码，直接进后台。重则通过 sql 直接写入后门文件直接控制网站。

设置禁止 ip 直接访问。

[chainsR]

nginx 装个 waf ，过几天你去看防护日志，会发现更多牛鬼蛇神

[AS4694lAS4808]

复杂服务在端口前加个 aws waf 。简单服务的话直接 fail2ban 读日志，禁用高频访问

冷知识，放到公网上总会被人扫描。不管就是了
