After you have finished creating a website, you should always pay attention to whether it is being attacked by hackers. Not only will this make content of web page cluttered, but it will also affect ranking of website. After a website has been created, if following situations occur, it can basically be judged that it has been hacked by hackers.
1. Traffic attack
There are two ways to attack traffic. One is that intruders can use a large number of data packets to bombard a website, resulting in paralysis, inability to function normally, and users being unable to access it. The other is to imitate countless users and constantly visit data-heavy pages on a website, which is extremely wasteful of server resources. Since CPU cannot finish processing data quickly, it will cause network congestion. In this scenario, normal users cannot access website.
2. The website database has been compromised
The process of creating a website will create a database that can be targeted by hackers. Once hackers break into database, they can change member information at will and even fake transaction information on platform. The worst situation could be that database gets deleted and members' privacy leaked, tarnishing corporate image. Therefore, it is recommended that an appropriate backup mechanism be installed when creating a website.
3. The page jumps inexplicably
Hackers can embed JS documents in web pages, and when normal users open web pages, they inexplicably navigate to other websites. For redirected target website, SEO ranking optimization can be easily completed, but for corporate website itself, ranking of its website will drop. To avoid this situation, web engineer should check JS document when jump occurs.
How to deal with hacker attacks after creation of site?
First, block site immediately. After a website is hacked, if network connection can be disconnected for first time, hacker attack can be stopped immediately.
Second, site design engineer checks extent of damage, including extent of damage to web page, whether database has been deleted, whether web page has a Trojan horse, etc. After determining extent of damage, a recovery plan is drawn up according to actual situation.
Finally, restore website data. On one hand, look for previous data backups and restore healthy data. On other hand, without a backup, a professional can restore website data. Once site is ready, certain protection measures are needed and it is up to professionals to fix the site.
