For an Internet enterprise, the biggest disaster is that the website server was invaded by hackers. While various hackers are trying to invade every server they can, how can we check whether the website server has been invaded and how can we deal with it after the website has been invaded? Now let's elaborate.

How to check whether the website server is invaded

The simplest way to check whether a website has been invaded is to directly search your own website. If the website is judged as dangerous by the search engine, or if the site has found many illegal information, it is certain that your website has been invaded.

Whether the website server is invaded can also be recognized by the following processes after all:

Step 1: View system groups and users. If you find that an admin $or similar user is added to the administrators group, it is very likely that your website has been invaded;

Step 2: Check whether the administrator account has abnormal login and publishing records

Select all system login logs and system publication logs, check their login ip specifically, and verify whether the ip is a commonly used administrator login ip;

Step 3: Check whether the server has abnormal startup items

Any abnormality of the above three processes may be caused by the server being invaded.

How to deal with the invasion of website server

1. Temporarily close the website

After the website is invaded, the most common situation is to be implanted with a Trojan horse. In order to ensure the safety of visitors, the website is usually temporarily closed. During the closing process, the domain name can be temporarily transferred to another website or a notification page.

2. Analyze the damage degree of the website

Some hackers will clear all the website data after invading the website. Assuming that the site with data backup can eventually rely on data backup to recover the website data, if there is no backup, you need to ask a professional hard disk data recovery company for data recovery. Assuming that the page data of the website has not changed, the website may just be hung up, and the third and fourth processes can eventually eliminate the impact.

3. Check the gap and patch it

After data recovery, you must scan the gaps in the website and patch it. The general website program official will regularly launch relevant patch files, as long as the file is uploaded to the server and covered up.

4. Trojans eradication

Trojans can be checked and killed by professional anti-virus software after all. It is important to pay special attention here that sometimes some normal files will be misjudged as viruses, which requires users to identify them carefully within a certain period of time.

5. Backup data frequently

Whether it is an enterprise station or an information station, the most important thing is to always back up data!
