Whenever there is a competition such as the European Cup, the World Cup and the Olympic Games, various gambling organizations will use all their efforts to hack out normal websites, especially those information websites with large traffic. During the European Cup, Baidu found that the number of website blackouts was increasing through internal detection, and Baidu has increased the intensity and efficiency of punishment. So, how to deal with website blackouts? As the webmaster of the website, how can we avoid being hacked? Today, Micron Network will take you to analyze it.
1、 The hacked websites have a feature in terms of data, that is, the number of indexes and traffic obtained from search engines have increased dramatically in a short time. Therefore, the webmaster can easily find the search tool on the Baidu webmaster platform, and observe whether there is any abnormality in the site's collection; If any abnormality is found, check whether the obtained keywords are related to the website, gambling and pornography through the traffic explosion and keyword tool.
2、 Query the website through the Site grammar, combined with some commonly used pornographic and gambling keywords, the effect is better, and it is possible to find illegal pages that do not belong to the website.
3、 Due to the huge traffic of Baidu, some hacked behaviors are only directed at the traffic brought by Baidu, which is difficult for webmasters to find. Therefore, when checking whether their websites are hacked, they must click the site page from Baidu's search results to see whether they jump to other websites.
4、 Prompt website content in search results for risks.
Then the website technicians can be asked to further confirm whether the website is still hacked through the background data and procedures, find problems and solve them in a timely manner.
5、 What should I do after the website is hacked?
After confirming that the site has been hacked, SEO personnel should not only promote technical personnel to make rapid modifications, but also do some remedial and preventive work.
1. Stop the website service immediately to avoid further impact on users and other websites (503 return code is recommended).
2. If multiple websites of the same host supplier are hacked in the same period, you can contact the host supplier and ask for a response.
3. Clean up the found black page content, set the black page to 404 dead link, and submit it through Baidu webmaster platform dead link submission tool.
4. Find the time that may be hacked, compare it with the file modification time on the server, and dispose of the files uploaded and modified by hackers; Check the user management settings on the server to confirm whether there are abnormal changes; Change the user access password on the server. Note: The possible hiding time can be determined from the access record. However, hackers can also modify server access logs.
5. Do a good job in the security work after that, strengthen the defense of your website, find the loopholes in the website, and prevent it from being hacked again, causing greater losses.
