Websites often come under attack with Japanese Keyword Hack one way or the other. If Japanese keywords are showing randomly on the website’s search results, then the matter can be perplexing. Those who are not sure of what’s happening should know that it is the result of malware on the website.

On many levels, the Japanese keyword attacks are confounding and concerning at the same time. A lot of website owners experienced numerous symptoms in the beginning. They often have been unable to access their sites. They have also faced redirects when trying to access them.

There are many who have experienced unknown users being added to their Google Search Console profiles. This caused a drop in ad revenue. The end result is Japanese text showing up in the search results on Google.

What is the Japanese keyword hack? – is it dangerous?

The Japanese keyword hack is a serious infection on a website. It is caused by malware. Hackers use it to inject Japanese text into web pages in a spam style. Once the page gets indexed by Search Engines (Google in particular), its appearance in the search engine results will be manipulated. The website will then begin ranking for keywords in Japanese.

Alternatively known as the Japanese keyword hack, it resembles the pharma hack and SEO spam hack. Why? Because it basically injects the website with spam keywords and spam pages. This helps improve other websites’ search rankings on Google.

This is a tactic used mostly by hackers. They do so to promote products, services, and websites which would not be originally allowed under the policies of Google and Google Ads. The products sold are either grey market or illegal (services too). Such malware can even redirect legitimate website users to spam websites.

The problem with malware attacks is that the average visitor cannot realize the malware attack the business faces. They will directly associate that experience with a poor experience.

It is only by coincidence a visitor finds out that all of this is due to malware. There are chances that they are going to be fearful of getting malware on their devices and would hence leave quite quickly. In either way, the business, brand, and/or company plus their website loses out on both business and customers alike.

The symptoms of a Japanese Hack attack on a website – What are they?

The Japanese keyword hack has a noticeable symptom, and that is Japanese characters in the website and the associated search results. But for those who are not going to check their search results regularly, there are more symptoms they should spot:

  • Japanese characters in the website’s search results. An obvious symptom of Japanese spam, it is shocking when encountered. Those who click through a result may see either a normal site or a 404 error page.
  • Lots of spam pages were added to the attacked site. Those pages are sometimes  added in but in large numbers. This is something observed in the search results. WordPress site owners will find it in the website’s database.
  • Hackers will usually add themselves to the Google Search Console Account. They do so to manipulate results for geo-location targeting and sitemaps. They will receive an email that someone else has verified themselves as an owner of the site’s Google Search Console profile. In case such behavior is not expected, it indicates that the website has malware.
  • Google Search Console will point out issues on the website.
  • Redirecting the visitor to another site from the spammed web pages.
  • Visitors of the site complain about unsavory, problematic, or spammed content.
  • The web host may suspend the website if malware is found on it. It hence becomes quite hard to deal with Japanese keyword hack attacks on WordPress websites.

Malware is inconsistent by nature. Hence there are chances that site owners will only see some of the symptoms mentioned above. They won’t see all of them at once. It is however true that coding errors cause these symptoms but it is quite unlikely. It is wise to keep everything safe and secure. Site owners must hence figure out if their website has an infection or is safe.

Malware unfortunately does not come with any warnings. People often discover after a while that the websites have been hacked. Detecting a malware attack late can cause more serious damage. Such damage can be irreversible sometimes.

Google has deindexed websites. Web hosting companies have suspended websites having malware. This is just the iceberg’s tip. Businesses, brands, and companies alike can lose the whole website because of malware missed from observation. Yet there are some ways to find malware:

  • Scanning the entire site for malware.
  • Deep scanning of the website using malware detectors (both manual and online).
  • Checking the website search results.
