Recently, I have met a lot of website customers who reported that they had been attacked by DDoS and CC, which is also a headache for developers, operators and maintenance personnel. At present, most websites use PHP,JAVA,.net as the development language and mysql,oracle as the database language. People in the IT industry all know that some corporate websites and personal stations do not have special security technical personnel to maintain, resulting in websites often being attacked, or taking advantage of loopholes to tamper with the home page of the site, jump to informal sites, and so on. What are the main symptoms of the attack on the website below?

One of the most common symptoms of website attack: the use of code vulnerabilities to insert malicious black chains into the website. This wave of operations can not see the existence of black chains when we open the website normally. It can only find black links by looking at the source code, and it is usually added to the pictures at the bottom or middle of the home page of the site, basically reducing the font of the hidden black chain. People can not find, the purpose of implanting black chain is to use the weight of the site in Baidu to get traffic.

The second of the most common symptoms of website attack: when opening the website, it will automatically jump to some cai tickets, Dubo and other illegal websites, and the home page files of the website will often be tampered with, the title and content description will be changed into cai tickets, dobo content, some will forcibly insert games on the page, and some severely attacked websites will be intercepted by Baidu's security center, resulting in poor experience of users visiting the site. Because of the loss of customers. When the home page of the website is tampered with, some will also tamper with the user's account password and other data information, so as to gain benefits and cause economic losses to the platform system and users.

The third of the most common symptoms of website attack: after opening the website, it is indicated that the database cannot be connected, then the reason for this inability to connect to the database may be that the attacker deleted the database maliciously or the code file of the website was deleted. It may also be the use of website code implanted with blackmail virus and so on.

The fourth of the most common symptoms of website attack: the speed of opening the website is fast and slow, or the CPU of the server is full, directly unable to open the website database process occupies a high, resulting in server stutter, unable to carry out remote operations, this situation can be determined as by DDOS traffic attacks and CC traffic attacks, through a large number of botnets or chickens to access requests, resulting in blockage, so that the site can not be opened. Above this kind of ink person security sees most is the peer carries on the malicious competition to each other's attack.

These are some of the attack techniques often seen by editors. Those who have different views can be sent out to communicate, so that everyone can know more. If you encounter an attack, you can immediately make appropriate solutions. This article mainly talks about the symptoms of the attack. The next article should talk about protective measures. I hope you can continue to pay attention to me!
