How to Fix Japanese Keyword Hack on WordPress and Secure Your Website

Websites powered by WordPress can be hacked or compromised. WordPress is a secure platform; however, there are often little things that webmasters don’t notice, which makes the service vulnerable. The attacker’s intent may be to add spam, delete your content, temporarily disrupt your business, and more. Japanese keyword hacking is one such technique that affects your website in many ways.

Luckily, if you detect that your WordPress Japanese keywords have been hacked, there are several ways to fix it. But what the hell is going on here? How does it affect your website? And how to protect your website?

What is a Japanese keyword hack?

If you find random Japanese text on your website, the Japanese keyword hack can affect your WordPress blog. If this is the case, your website has been altered by malware that adds or generates Japanese text and spam links.

When users find your site or product on Google and other search engines, Japanese text appears in search results. You may also notice that new pages on your site only contain spam links and Japanese text all over the place.

The quickest way to check it is to search for your website page on Google using the following format, substituting your domain:

Website: Japan

When your website is infected with this kind of hack, the links in your website will point to fake web pages or malicious platforms which may encourage your visitors to share information to get free prizes or be tricked into buying something.

How did this hacker infect your WordPress site?

WordPress is a platform where pages are made up of various elements, so there are a number of reasons why a website is affected by the Japanese keyword hack.

Running an older WordPress version

WordPress regularly releases security patches and bug fixes to keep the platform as secure as possible. If you haven’t applied available updates for a long time, attackers could exploit these vulnerabilities to infect your website.

Using broken plugins

One of the superpowers you get with WordPress is its plugins. Unfortunately, not every plugin is safe.

You must make sure to only use plugins that are reputable and not brand new.

Also, you should only use fewer plugins based on your requirements. The more plugins you use, the better chance you have of choosing something that might not be safe.

Show invalid topics

WordPress gives you complete freedom to upload third-party themes or customize your own.

Sometimes users upload cracked (or invalid) themes instead of buying a license. Unfortunately, these files often contain malicious code or do not receive updates, which makes them less secure.

Apart from the above reasons, there are many other reasons such as:

  • No strict file permissions.
  • The login password is weak.
  • There is no two-factor authentication.

How to Fix Japanese Keyword Hack

Managing and securing a website can be overwhelming. But what can you do if your website is compromised? Here are some great solutions.

1. Use an all-in-one security tool

Many WordPress security plugins (like Wordfence or Malcare) help you recover your site from hackers in a few easy steps (or clicks).

Most services cost money. However, if you want to save time and fight malware infections, you should give it a try.

2. Scan for Malware

Some web servers offer free access to tools like Immunify360 Security Suite, which can help you scan for malware and enhance your website security.

If the tool finds anything, you can eliminate the problem.

You can also use a website malware scanner to check that your website is clean.

3. Check file modification

You can go to the file manager portal in the server or view the logs to identify recent file modifications.

If you find content that has not been authorized or added by you, you can try to restore the file to its original state or delete it (in some cases this may render the website inaccessible, so do this step with caution).

4. Restore the site from backup

It is often easier to restore your site to the state it was in before the WordPress site was infected. Restoring your site to a previous version may not be useful if you don’t know when the site was compromised.

In most cases, your hosting provider can automatically backup your website. You can configure other backup solutions and use them to restore your website.

5. Reinstall WordPress

Sometimes a malware infection like the Japanese keyword hack may focus on modifying core WordPress files. A malware scanner should spot this for you. In this case, you can simply reinstall WordPress without touching any other files on the server.

Things to do after cleaning up the hack

Removing malware is not enough. When your website is infected, it marks your website in various ways:

  • Google may flag your site as malicious.
  • The web host may suspend your website.
  • A new site owner may be added to your Google Search Console account.
  • Your customers may no longer trust your website.

To fix these issues, you need to take some extra steps after fixing the Japanese keyword hack on your WordPress site.

1. Fix your Google and search engine issues

Since an attacker has access to your website, they can say they own it and add the user to your Google Search Console as an admin. If you see any unauthorized users listed, delete them. See Google’s documentation for details. If Google flags it as malicious, you may need to request a review.

Also, you should reindex your site on search engines to prevent spam pages from appearing in the results.

2. Clean your WordPress database

WordPress Japanese keyword hack adds several posts with spam and malicious content to your website. If it exists on your sitemap, it may still show up on Google.

This may not be necessary if you restored a previous version of your site.

You should consult a professional for this or try a WordPress database plugin to help you deal with it.

3. Update everything

You should update all your themes, WordPress platform, and plugins to ensure there are no known vulnerabilities affecting your site’s security.

How to protect your website

There are many steps involved in securing a website. Here are some quick tips:

  • Enforce strict rules for web server file access.
  • Add stronger authentication methods for login, such as two-factor authentication.
  • If you haven’t implemented SSL (HTTPS).
  • Use a Web Application Firewall (WAF).
  • Deliver assets securely using a content delivery network.

Keep it simple to avoid website threats

The more elements you add to your website, the more regular maintenance and different techniques are required to ensure security.

The best way to prevent your website from being hacked is to keep things simple, clean and up to date.
