Blockchain security consulting company Qusu Future stated: On December 15th, Nantong Public Security Bureau announced to the outside world that in the "Net Net 2020" special operation, it successfully cracked a case of massive destruction of computer information systems and arrested 7 suspects. Cut off a chain of interests in online black and gray industries.
The criminal group rented an overseas server to build a network attack platform, and made profits by developing agents and selling member accounts. Since the second half of last year, traffic attacks have been carried out on more than 5,000 websites and more than 1 million yuan of illegal profits have been made.
It is understood that in June of this year, the Network Security Detachment of the Nantong Public Security Bureau received a report from the person in charge of a video website saying that its website had frequent video freezes and downtime recently, causing huge losses and suspected of being attacked by hackers. After electronic data forensics, a total of 17 audio and video servers and 10 relay login servers were attacked from time to time. After receiving the report, the Nantong Internet Police investigated and found that multiple video platform websites across the country have suffered similar attacks.
Speaking of DDoS, frequent attacks on websites make people shudder when they mention it.
DDoS attacks, called Distributed Denial of Service (Distributed Denial of Service) attacks, are one of the most common network attack methods. The attacker launches an attack on the target server by manipulating multiple computers in different areas. The purpose is to force the other party's network or system resources to be exhausted and to suspend the service, making normal users inaccessible.
With the rapid development of the Internet, DDoS attacks have become increasingly rampant. From the original few megabytes and tens of megabytes to the current traffic attacks of tens of G and tens of T, a large chain of interests has been formed. After the website was attacked by DDoS, normal legitimate users were unable to obtain services, and the platform’s live video streaming was frequently stuck, which brought a huge impact to the security of the website.
In recent years, DDoS traffic attacks have occurred frequently, and the complexity and scale of attacks have continued to increase. They have gradually become one of the main criminal methods of blackmail, unfair competition and other illegal crimes, causing huge economic losses to victims. According to statistics, in addition to game companies, government websites, corporate service websites, and even financial companies have long been the preferred targets of DDoS attacks. During the attack, the online game cannot be logged in normally, and the online payment is stuck or even the transaction cannot be completed. If the attack continues for many years, it will make the user experience worse and turn to seek services from other providers, which will affect the direct interests of online game companies or Internet service providers.
DDoS attacks are frequent, and network security cannot be ignored. Currently facing various types of DDoS attacks, there are two most common solutions:
1. If the attack traffic is not very large, you can directly increase the bandwidth through the computer room to hardly resist, but if it is a large traffic attack, this method is not enough;
2. A professional network security company like Qusu Mirai must be used to defend against a large traffic attack. Enterprises can configure the future high-defense IP of Qusu to make all visits go through the high-defense IP first. If there is a DDOS/CC attack, it will automatically identify and clean, and forward normal traffic to the source server to ensure the stable operation of the server.
Qusu Future, a blockchain security consulting company, said: The current Internet environment is becoming more and more complex, and network attacks are becoming more and more frequent. The impact and losses on major Internet companies are also increasing. In order to ensure the stable operation of servers In the future, it is recommended to choose suitable high-defense products in advance, and don’t wait until the server crashes to find a way. The loss at that time will be irreparable.
