Log Every User Out and Everywhere

Your WordPress admin page is the first place hackers use to inject malware codes that would bring the SEO Spam hack to your WordPress website. If your WordPress login password has been compromised, it needs to be changed. And that is a big “IF”. Especially when you are running a WordPress website that enables different admin users. The best thing to do is to use the admin user access and log everyone out.  To do this, go to users, navigate to profile, scroll down to Account Management.  At sessions,  click on log out everywhere else, as shown below.

Use Google Search Console

The google search console helps you to get your website noticed and discovered on Google search results. IF your contents are already showing up on Google search. The chances are that you are already using the Google search console. To login into your Google Console account, use this link. You may have to log in and verify that you own the domain. If you don’t know how to do this, use Google search or any other search engine to find answers, and if it still confuses you, leave a query regarding this in the comment section.

Checking for Infected Japanese SEO backlinks

The links would display all your backlinks. You can copy each of the website links and put them on a separate browser to test the links. For the example website used in this tutorial, most of the backlinks were porn sites, casinos, clothing websites etc.

If these websites are allowed for long they could use up your bandwidth rapidly.

When your website is infected with Japanese keyword hack virus, the search results on Google displays pages that have your domain name but the title of those pages can be very misleading.

Keyword Spam pages

The picture above shows the search results of our website infected with the Japanese SEO Spam virus. But looking closely, the pages displayed are numbered 1, 2, and 3.  The number 1 page is the homepage of the website. However, the page it is pointing to was written in a language that can not be understood by English-speaking users, this is also Number 2. The number 3 result was from the shop page, but rather than the electronics components and kits on display at the online shop, it is displaying a Hussein dress shirt. These pages are still linked to our website’s contents. Although it doesn’t display its page content on Google search results correctly, once clicked on, it will take online visitors to our pages.

Heavily infected SEO spam

On the other hand, majority of the pages are pointing to another SEO page content. As illustrated with the picture of our website above, the pages here drive traffic away from our  website. They are something like “aco136”, “dft353” “zqcum” etc. If a visitor clicks on any of these links, it would take them to the hackers backlinked website pages instead.

Usually, the Japanese SEO hacker pages are non-mobile-friendly and very slow to load, and it could really drive visitors away from your website. Most people don’t have the time to wait until a slow loading page finishes loading. It could also make Google blacklist your website. To tackle this issue, go ahead and log into your WordPress admin page again.

Remove Japanese Keyword Hack: Backup your WordPress Content

The backing up of your contents on your WordPress site is also important. However, most of the backups required you to pay for such server services. There are other ways you can get around this. For example, you can use the UpdraftPlus plugin to backup contents on your Google Drive account, provided you have enough storage space there.  Whether you choose this option or not, you can still proceed to the next step.

Download and Install Wordfence Security Plugin

Malware scan results

From the scan results, we could either delete  or repair the files that are corrupt. I would recommend repairing the repairable files. Then deleting the files that are not repairable.  Click on repair all repairable files and wait for the system to repair the files it can repair. These are the small steps that would lead to a giant leap on our search for how to fix/remove Japanese keyword hack/Japanese SEO hack free.

Next, for the files that are not repairable, you can either delete them or click on the details of each file to view the severity of each infected file. You can check out the difference in each file to see the changes in each file.

Wordfence File Difference viewer

From the file difference, we can see a lot of things on this .php file. This was the exact file that was corrupted that made it possible for the Japanese keyword hack/Japanese SEO spam. From the left hand side of this comparison, we can see the original .php file versus the file that was modified by the hacker on the right hand side. The solution to this can’t be resolved automatically by Wordfence because the .php file is a file on the cPanel side. The Wordfence plugin doesn’t have access to the file.

Get the location of the corrupt file by looking at its directory path above on the Wordfence file viewer as shown below.

cPanel file directory path

Using this, we locate the file in the cPanel public_html directory.

The results shown would still remain the same on Google search results but we are really after the functionality. This means we want to know if the backlinks still redirects visitors to the hackers page.
