Hi guys this is my first post on wpcult the great site Austin built.  Hope you guys find it usefull.

If you run a blog using the wordpress software then your blog is a target to hackers.  Below I will list some hacks and just how they can help you keep your business/site safe.

The following is  code to Block Bad Queries and protect your blog from malicious URL Requests.

Place the following code into a text file and name it what ever you like for example blockbadqueries.php upload it to your plugin folder and activate it in your wordpress admin just as you would any other Plugin

<?php
/*
Plugin Name: Block Bad Queries
Plugin URI: http://perishablepress.com/press/2009/12/22/protect-wordpress-against-malicious-url-requests/
Description: Protect WordPress Against Malicious URL Requests
Author URI: http://perishablepress.com/
Author: Perishable Press
Version: 1.0
*/
global $user_ID; if($user_ID) {
  if(!current_user_can(‘level_10’)) {
    if (strlen($_SERVER[‘REQUEST_URI’]) > 255 ||
      strpos($_SERVER[‘REQUEST_URI’], “eval(“) ||
      strpos($_SERVER[‘REQUEST_URI’], “CONCAT”) ||
      strpos($_SERVER[‘REQUEST_URI’], “UNION+SELECT”) ||
      strpos($_SERVER[‘REQUEST_URI’], “base64”)) {
        @header(“HTTP/1.1 414 Request-URI Too Long”);
 @header(“Status: 414 Request-URI Too Long”);
 @header(“Connection: Close”);
 @exit;
    }
  }
}
?>

 This Great plugin was made by Jeff Starr of Digging into WordPress

 

 

Protecting your blog with .htaccess 

.htaccess files have lots of possibilities. below is some code that will help protect your wordpress from modification of _REQUEST and/or GLOBALS and scripts injection.

 This is real simple just paste the following code into your .htaccess file. Always make a backup of your .htaccess before editing, better to be safe.

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{QUERY_STRING} (\<|%3C).*script.*(\>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
RewriteRule ^(.*)$ index.php [F,L]

 

Thanks to Oussama for this great hack

    It’s not a very secure place, the internet, is it?! I can’t believe how much trouble I have to go to as a blogger to ensure everything is a) working and b) secure!

    Ah well!

    GREAT POST! Seriously.. I recently had a few sites down due to very similar issues. I think it was automated SQL Injections from the looks of things.. Anyhow – strong first post and good information to boot.

    Thanks for that very useful information. I was looking for some security method for my blog ever since I started my blog. I think my search has come to an end now. I will surely try this.

    Nice first blog post. Internet security in general is often overlooked as unneccesary. This is a fatal mistake, and WordPress users can fall foul of prey!

    More people need to know how to configure their .htaccess files. As a matter of fact, I just compared your recommended settings to my own – I need to make a few tweaks. Thanks for the informative article.

    Wow.. useful to know, I had no idea that there was this kind of issue with WP. I once had a script injection attack on a regular html web site I was running, and my web host gave me a javascript to put in the site which would protect it from those kinds of events in the future. I don’t quite understand all the terms you use – what’s a ‘malicious URL request’? Is that an automated request sent by a bot?

    This is something dangerous and can be very harmful for the wordpress users. I think wordpress should be careful about it otherwise it can have serious security problem.

    I’m constantly worried about securing my wordpress. I use the bad behavior plugin which I think is similar to the plugin in your post. I see hack attempts in my log files all the time but so far I think so good.

    WordPress needs no introduction because it is currently creating lots of waves on the internet at the moment. Some people had gotten their fingers burnt by activities of some online criminals that specialize in stealing information that are in other peoples’ sites and blogs.

    You must have the latest version of WordPress if you want to be protected. This plugin seems to be very easy to use. However I prefer the protection made from the .htaccess file, exactly like in this tutorial.

    You state that this code is to “block bad queries”. What exactly does that mean? How do you define a “bad query”?

    I know this thread is getting old now but WordPress hacking is still a real issue. We have a large number of sites built on WordPress and many of them have been hacked as recent as the last 2 weeks. Real bad hacks as well with the database wiped and everything. It’s a pain because WordPress is such a great platform to use and very popular with our clients – they love the easy CMS. Wish we could fix WordPress hacking once and for all…!

Echo custom fields in any category

Published

Here is a neat trick. Say you want to show a custom field in you post or in a certain categories post. There is a simple code you need to write in order to accomplish this:

<?php $image = get_post_meta($post->ID, "image", $single = true); ?>
<?php if($image != '') : if(in_category(7)) { echo ''; } else { ?>
<img src="<?php echo $image ?>" alt="<?php the_title(); ?>" /></a>

In the example above I am calling the variable $image and telling the server that it equals the value of “image” inside get_post_meta or “custom field” of the current post.

Then we are asking if that variable $image doesn’t equal nothing or != and if it is in the category id of 7, echo what ever is in the single quotes (which is nothing in this example), otherwise show the <img> and the value inside “image” which should be the location of the image.

Update: Thanks to Austin from PressedWords for pointing out his trick, from the comment below.

I talked about Disabling search engine on search pages in a previous post using the meta tag. Today lets go over the web bots Cached copy of your site. If you are working on builder your blog, or have a temporary site up, use the following code:

<meta name="robots" content="noarchive">

This will tell any bot to follow your site, index it, but prevents a cached copy of this page from being available in the search results.

A good idea when trying to get the most out of your blog is usging the meta tag to tell the web bots to search & index your site. But for good SEO you should apply this code in your header.php file of your WordPress blog.

<?php if(is_search()) { ?>
<meta name="robots" content="noindex, nofollow" />
<?php }?>

This will keep your site from getting a hit from bots over duplicate entries. 🙂
