This article shows you how to solve the malicious code implanted into the website in website development. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

How to quickly resume the normal visit of the website after being hacked

First of all, by logging in to ftp, if you do not have ftp information, you can request it from the construction company that originally made the website, and then log in to ftp to see if any encrypted garbled code has been added to the home page as shown in the figure:

The garbled code is converted by Unicode coding, and then the garbled code becomes harmful information as shown in the figure:

These garbled codes contain jump codes, and those entered through Baidu search keywords will be directly redirected to other websites, but will not jump if you directly enter the domain name of the website. This is because the hacker judged the source of the customer's visit. If there are these garbled codes, please remove them immediately. The easiest way is to find the original index.php program files and replace them directly, then delete all the files named by indax, compare the modification time of the files, see which ones have been tampered with, and delete them at the same time. The company's website has been hacked for some time, Baidu's snapshot has also been tampered with, and the site snapshot has been jumped and hijacked to other websites. As a result, the keyword rankings of the website have been dropped, resulting in heavy losses.

What is the reason that the home page of the website is always modified?

Because the website program code was originally used by the website construction company using the open source program code developed by the dedecms program, and the site construction company did not care about security issues at all, only designed the function and appearance, resulting in the program code can be exploited by hackers to attack the website loopholes and upload the Trojan back door to control the site, the Trojan backdoor has great authority to modify and upload any files of the website to the directory. And some hackers tampered with the login page of the website management background in order to achieve the effect of permanent Trojan horse, adding xss cross-site script to the login page, resulting in each login background will be recorded and transmitted to the maker of xss cross-site scripting attacks, then hackers can directly use cookies to log in to the background for operation. If you are not familiar with the program code, it is recommended to find a professional website company to repair website vulnerabilities. Domestic companies that do better, such as Green Alliance, Sine Security, Qiming Star and so on, are all powerful security companies. after all, personal technology is limited and can only clean up some malicious code, but it can only be solved for a while to restore normal access to the website, but it is not long before it is tampered with and redirected.

Suggestions on how to fix website loopholes

1, upgrade the source code of the website program and filter the upload directory of the website.

2, modify the administrative background directory of the website and do not log in with a name such as the default admin,dede,houtai.

3, the administrator's account and password must not use weak passwords, be sure to use letters plus numbers or symbols of 12-to 18-digit passwords.

4. Restrict the upload function of the website and delete the upload function code file directly if necessary.

5. Make a full backup of the website and database frequently to prevent the data from being deleted.
