In this issue, the editor will bring you how to solve the problem that the website file of the virtual host is implanted into the Trojan horse. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

If there is a file upload loophole in the website, hackers can use this loophole to upload hacker files. It is common that hackers can then modify all the files on the user's website at will.

In view of this implanted Trojan horse, users need to find a technician to check out the website vulnerabilities and thoroughly repair them, and check to see if there are any malicious files hidden by hackers. The key is to let users know where the file upload function is used on the site.

Focus on this file upload function to check, at the same time for all documents on the site to check for suspicious information. At the same time, the website log is also used to check the time when the file was modified.

1. Find out which file was added to the code. Users want to view their own web page code. According to the location of the added code, to determine which page is hacked, the hacker will generally modify the database connection file or the file at the top / bottom of the site, because all pages of the user's site will be appended after the modification.

2, after finding the tampered file, use FTP to view the time when the file was last modified. For example, if you see the conn.asp file hacked inside FTP, and the last modification time is 12:30 of a certain day, then you can be sure that at this time at 12:30 that day, a hacker used the hacker back door he left behind to tamper with your conn.asp file.

When clearing Trojans, you should pay attention to:

1. After many users' websites have been hacked, they will only correct the files that have been changed, or upload them again, which does not have much effect. If the website space does not fix the loophole, the hacker can quickly exploit the loophole again and invade the user's website again.

2. The inspection and repair of website loopholes need certain professional and technical personnel to deal with. Users need to make a backup of the files first.
