那些专职搞破坏的畜生
从开始接触互联网，应该还是2000年左右，记得当时和一个小电脑专卖店老板关系不错，他拉了一条联通的100M的光纤到办公室，还带有固定IP。要知道，那时绝大部分国内互联网用户都还只是使用电话线来拔号上网，网速只有56K的样子。网吧倒是10M/100M，不过毕竟不带固定IP的。然后老板在办公室搞了一台电脑，装了个WIN2000，用作服务器。
那时候我就开始倒腾这台电脑，在上面装上asp/IIS环境，搞几个小网站玩。
结果有一天深夜，发现电脑数据有些奇怪，好多文件都打不开。重启电脑，发现所有文档全部消失，桌面上还有遗留的文档让打钱找回文档。这才意识到碰到黑客。之前大家都没什么安全意识的，还好电脑里也没什么重要资料，直接格式化重装，然后稍微设置了一下安全策略。
这是我第一次碰到黑客。
后面应该在2017年左右，我心血来潮在客厅里搞了一个小服务器，自己组的DIY电脑，主要用来远程下载，还有在家里的电视、手机上看电影，还有存放一些下载的电子书之类的东西。服务器装的是ESXI，虚拟了好多个系统，其中有个WIN10系统，我又打通了这个WIN10的主要端口到外网，方便在公司也能远程连接上去。
某天晚上也不知道发什么病，居然把超级管理员Administrator的密码，改成了123456，因为弄得太晚，就忘记修改回来了。结果第二天早上起来一看，中了勒索木马，所有文件全部上锁，让打比特币解锁。
没办法，只能删除这个虚拟机，重新挂一个上去。
第是我第二次碰到黑客。
后来就一直在玩云服务器，结果首先要解决的问题，就是遍布全网的暴力破解问题。
查询linux服务器SSH登录失败日志
使用以下命令查询SSH登录失败log：
utmpdump /var/log/btmp不出意外，你就能看到一屏一屏的失败信息滚过。如果你一周不清理，你看下能滚个几分钟信不信？
防范措施
- 修改SSH端口
- 仅使用密钥登录
- 使用虚拟局域网，只允许特定内网IP登录
- 安装fail2ban来灵活封锁疑似IP
以上安装大家可以去搜索一下就好。实在不会，安装个宝塔，在安全里直接设置也比较方便。
今天想说的是，我查了一下我所有VPS的被fail2ban给封锁的IP来源。
大厂一般来说，有专门的网络安全配置，比如阿里云、腾讯云、亚马逊云、甲骨文云、UCLOUD等等，都有。不过我还有一些在国外淘的一些小厂VPS，这些只能依靠在系统里的安全措施保证自身安全。
今天去查了一下，上次说的那个性能非常差的土耳其VPS，fail2ban居然封锁了623个IP。。。

好家伙，，，这是招了马蜂窝了
统计了一下：
看看排名，第一名比第二名多出一倍多。
运营商的分析，除了未知IP，前七位，基本全是国内运营商。
你们说，这说明了啥？
无语
什么样的环境成就什么样的人，和人生。
很多人会说，就说这个土耳其的小小小小运营商，能在那里买VPS的，会有什么重要的数据资料放在那里？甚至估计大部分连生产环境都不算。你破解，就算成功了，有个毛线的意义。
然而我们还是太年轻，这就像电诈一样，数据重要不重要，它这个事不重要，有人中招，中招的面积大了，总会有那么一点概率会有人打款的，对于那些畜生而言，就够了。
然而，那么多国内的服务器IP，要么蠢到用自己服务器去直接扫描，要么都成为了黑客们的肉鸡，被他们控制去进行扫描破解的活动，就这网络安全环境，那得差到什么地步？
我个人还是坚持认为，肉鸡很多，但一般不会这么用，所以，还是国内有太多心思不正常的畜生。
为什么？
没人管呗！
不发展到一定地步，他们是真的不会管的。祖孙几代都稳稳的吃喝贪腐，几千年的经验就是，没自己利益的事，不管。
这就造成了太多类似这种情况的局面，电诈是一个，什么地产、金融、足球。。。。方方面面，都是一样。
唉，可怎么办哟。。。。
只能说，趋势应该就到了，只是还缺少一根稻草。
