How does this happen? This process can take place due to multiple issues. A common cause is that some developers build websites using hacked template or themes. Which can create a chain of multiple backdoor access to hackers that will install spam content, divert guests to different destinations, introduce infections on guest’s computer, and gather sensitive data from your website? If your website was built using Joomla or WordPress, then the use of nulled or outdated plugins can cause the same effect. If you find that your website might be compromised then head over to Sucuri and scan your website for malware. This will help determine the cause. Another common cause is due to multiple user’s access to the websites. Securing your passwords and prevent sharing amongst users is the key to preventing hacks.
How to prevent such incident? If you haven’t already done so and or think that your site was incorrectly flagged, then register your site in Search Console and then head over to Security issues and look for a notification or URL that Google has crawled and flagged as infected. If for any reason you are unable to see the URL under Security issues, that could mean that the hacker is using a method technically known as Cloaking. This can cause the site URL to changes for each user, preventing the detection and cleaning process much harder. If cloaking is being used, then you will need to use Googles Troubleshooting methods in order to uncover the URLS.
Submit site for Review Once you are sure all malware and infected files have been removed or cleaned than this time to resubmit your site for Google to review. Navigate over to Google Search Console and resubmit the website under Security issues. Google will then double check to ensure infected files and content are secured. This site review process can take up to 24-72 hours to complete and once completed you will be notified at the email address on your Google Search Console account.
