The average daily IP of the website is over 1,000 to only half a hundred in a short time. Is the traffic hijacked? Or is it a natural phenomenon? What is wrong with our website? First of all, under Baidu’s site, I found the website title and Baidu snapshot included in Baidu’s site. The actual title was different. The website showed some lottery content in Baidu's snapshot content. After entering from Baidu, it jumped directly to the lottery website. I immediately checked the contents of the website directory and found that some suspicious file contents were uploaded.
Through analysis, it is found that the Baidu snapshot of the website is hijacked and redirected, that is, when you search for keywords on Baidu, the content of the snapshot displayed in the search results is not the content of your website, but some bad information, about lottery tickets, etc. and the website Irrelevant content, this is how Baidu snapshots were hijacked.
How to solve Baidu snapshot being hijacked?
First connect to the website’s FTP, download the website’s index.html file, find the title tag at the top of the file, and check if some code that does not belong to the website itself has been added to index.html, our title, description, and keyword tags on the home page Some encrypted special codes were found in it.
Remove the above-mentioned encrypted code immediately, and then upload it again (if the whole site is hacked, it can only be completely removed). After solving the problem of malicious code on the website, we need to strengthen the security of the website, such as Repair the vulnerabilities of the website and clean up the backdoor of the website Trojan horse, set the security settings of the website folders, prohibit the write permission of the root directory and other security operations, so as to prevent the website from being attacked again!
If your website has cleaned up the code and it was repeatedly tampered with before long, and Baidu snapshots are still hijacked, the source code and files of the website should be checked for security, and malicious links and Trojan horse backdoors should be removed.
After the malicious code and the Trojan horse backdoor are removed, the website vulnerabilities are also fixed. You should submit an appeal to Baidu and submit Baidu snapshot updates to Baidu. Wait for Baidu manual review. If the submission review is notified by the email and failed the review, thank you for your feedback. The website has previously detected malicious content. In order to confirm that the website will not repeatedly appear malicious content, continuous monitoring is required.
