Fix WordPress injection Hidden Link

The injection exploit hidden WordPress Link has been the cause of concern for many users who use WordPress on a daily basis. For those unfamiliar with the subject, the attack is inserted links to the files in your WordPress theme active mostly aimed at adult material elsewhere on the web. The lainks are completely hidden from view so you can never know about them and or their visitors. But the search engines definitely pick - and penalizing it.

Detection

See if your installation has been compromised WordPress is easy. Just look at the source code for your page start and look for any code that does not belong. Check the top and bottom of the file, since it is the place I've found the hidden links that exist mostly. They are also usually wrapped in HTML comments.

<- S ->

Some web site

Some web 2

...

N a website

<- E ->

If that's the code that way, chances are, you are a victim of the exploitation of hidden injection WordPress Link.

How are "they" doing this?

Apparently there was a security hole in WordPress 2.8.x versions that allows users outside of kidnapping the / wp-admin/upload.php and insert files to the server could be used for all types of malicious purposes. One of purposes is the hidden link injection. WordPress 2.9 fixed this hole, however, just the update is not enough. External users will no longer be able to upload.php kidnap but that files already inserted even orchestrating the attack.

That's why simply removing the links or footer.php header.php (The two places I've seen the links) is not enough. You will notice that the links just reappear. We have to treat the disease now, not just the symptom.

Solving the problem

First and foremost, keep your WordPress Installation up to date! The update could not be easier. Simply click on the alert that appears at the top of your desktop and follow the instructions. It takes literally 10 seconds.

Then change the admin password is WordPress. Also change the password for the MySQL user.

Finally, search files that have been included for the working through upload.php. I found two separate instances of these files, both located in the folder wp-includes. Check permissions of each file wp-includes and investigate any file that has the permission 777 (which is the first indication that something is wrong). atom2.php rss.php class and feed are two files that I have seen problems cause. Attractive, the. These two files are not native to the WordPress Code base and can be removed safely. If you were to open any of these files and know a little PHP, you will see that these files are indeed the culprit.

Go through these measures should ensure the installation WordPress against the exploitation of hidden link injection.

Stay alert

The fact that we have set this is not guarantee that you will be immune forever. Hackers are constantly seeking new and better ways to break stuff up. WordPress has been exceptionally good in security patches, but someone somewhere has to be the guinea pig to get hit with an attack - and then report it to WordPress.

A great plugin that I started using WordPress is Monitor files. This plugin scans your WordPress installation, and reports if the files have been added, deleted or modified. The plugin can be customized to run on a schedule you define. You can also exclude directories plug-in reports not to warn every time you get a picture to insert in a message. I, however, you should not exclude the directories and directory may be the next location of the holding is coming.
