Reasons for virus code implantation on servers or websites

Generally, there are three reasons for virus code implanted on servers or websites:

1. There is a problem with the web site code of the VM, which is caused by a security vulnerability.

If most users' websites on the server are normal and only a small number of users' websites are hacked, it is likely that a small number of users' websites are hacked due to website code problems and security vulnerabilities. This problem cannot be solved, nor is it the responsibility of the service provider.

As we all know, the "VM provider" assigns FSO file operation permissions to each of its VM users through the legal permissions assigned by you, any file that can be modified or uploaded at will. If the user does not protect the legitimate permissions that you assign to them, and hackers can take advantage of them, then hackers can use the legitimate permissions to destroy the website, however, most users think that this hacker intrusion is not caused by him, but by the service provider. In fact, this is a waste of service providers. For example, if you use insecure programs such as "Mobile Network Forum", the Code Design of these programs has vulnerabilities, which are easily exploited by hackers to upload webpage Trojans, hackers can manipulate webpage Trojans, use valid permissions to damage your user data and modify webpage files, and even cause the website to be completely inaccessible. These methods are the most common "Problems with customers' website code and security vulnerabilities ".

2. It is caused by server intrusion.

When virus code is implanted on all websites on the server, and the virus code file can be found at the end or header of the source file, or the Add script is implanted in IIS, it indicates that the server is infiltrated.

3. It is caused by ARP virus in the server room.

When virus code is implanted on all websites on the server, and the virus code file cannot be found at the end or header of the source file, ARP virus is detected in the server room. In this case, you need to contact us to solve the problem. Generally, there will be a lot of server viruses in the data center, and many customers will respond to the data center. Generally, the data center will handle the problem within half an hour.
