A hacker attack usually only becomes apparent through its consequences when it seems to be too late - the page's ranking drops for the relevant keywords, and instead the page now appears in the SERPs for the wrong keywords. Common content management systems such as WordPress are particularly vulnerable to such attacks if the system, plugins or templates are out of date. For this reason, regular updates and backups are essential. As in so many crisis situations, the same applies to a hacker attack: keep calm and proceed in a structured manner. But what exactly do you do if your own site has been hacked? John Müller from Google recently explained this in a Google Webmaster Hangout .
1. Change passwords
First of all, you should change all passwords related to the website, such as the CMS, database and FTP client password. This measure does not always help, but it can ensure that hackers' access is blocked.
2. Fix security vulnerabilities and remove compromised data
Of course, you should remove all data entered by the rcs data indonesia hacker and restore the actual content of your website. Don't forget to check Google Analytics and Google Search Console. If the hacker has set up access there, he can still influence your website. If Google notices the hacker attack and notifies you, for example, the hacker could tell Google that the problem has already been resolved and you won't notice.
3. Restore XML sitemap
If your XML sitemap was changed during the attack, you should update it as well. Many modern content management systems automatically update the sitemap at regular intervals.
Changes are often very hidden so that the hacker attack remains undetected for as long as possible. The manipulations are often only visible to search engines or not even recognizable in the SERPs. In the case of so-called phishing attacks in particular, the hackers set the modified pages to "noindex". If you follow all of these steps, your website's ranking should return to normal within a few weeks. If you are not familiar enough with your own system, it is best to get an expert to help you. Google also announced that successful hacker attacks and the associated changes to the ranking will not be penalized by them and therefore will have no influence on future rankings.
