With the rapid development of the Internet, network attack incidents have gradually occurred frequently, so it has attracted the attention and attention of various industries, because it has formed a serious threat to network security and even national security. Then there are several common forms of website attacks. Which ones? Here are the details:
1. Website domain name dns hijacking
Open your own website, but the content is not your own website content. Check whether the server and website programs are normal. In this case, when we ping the website ip, it is no longer our own server ip. In this case, DNS hijacking of domain names often occurs. Its purpose is malicious attack to show off or advertise benefits. The attacked sites are all types of sites.
2. The website page opens and automatically jumps to other website pages
This form is often called an illegal bridge page, a forced return js implanted in a web page, or an intrusion on the server, and a 301 redirection jump in IIS, the purpose of which is to allow hackers to carry out some illegal advertisements or website authorization . Transfer and benefit from it. The targets of attack are often websites with authority and traffic.
3. There are a lot of black links on the website page
The web pages of the website look normal to ordinary users, but in the source code of the website, there are often a large number of anchor text links at the bottom, and these links are often hidden, with a font size of 0 or extremely cheap positions. The purpose of the attack is that some hackers illegally implant links to increase the weight and traffic of some low-weight websites in order to obtain benefits, and the attacked websites are often punished with downgrades. The attacked websites are usually websites with certain search engine authority and traffic.
4. A large number of embedded web pages appear in the root directory of the website
If the website is not maintained in time, you will find that the website suddenly skyrockets, and the content contained is not the content of your own website, most of which are illegal advertising pages, such as gambling, pornography, game private server plug-ins, etc. We check the server website data and find a large number of implanted Static pages. A wide range of websites have been attacked, especially some websites with large traffic are more favored by hackers.
5. The website server runs slowly, and viruses such as worms have been implanted
Sometimes webmasters find that the site is running an update or that the server is running very slowly. When we look at the process management of the server, we will find that there are processes running, taking up high cpu and high memory. This is a type of Trojan horse that is often found with viruses such as worms. Its purpose is to occupy website resources, or the server itself is attacked and invaded, as a platform for "broilers" to attack others. The websites under attack are usually high-performance, high-bandwidth servers.
