If a service needs to be public-oriented, it needs to provide a user access interface. These interfaces just give hackers the opportunity to take advantage of them. For example, the TCP/IP protocol handshake defect can be used to consume the link resources of the server, The stateless mechanism of UDP protocol can be used to forge a large number of UDP data packets to block communication channels... It can be said that the world of the Internet has not lacked attack points exploited by DDoS since its birth, from TCP/IP protocol mechanism to CC, DNS and NTP reflection attacks, and what's more, it uses various application vulnerabilities to launch more advanced and accurate attacks.可是我病了，连酒也喝不下。妙子的上司·糸川也因为妻子逃跑而感到寂寞，于是用APP与女大学生·实日子（山本舞香饰）进行了匹配，但实日子的目的是“吃饭”…。Some of these changes may be felt by oneself, thus realizing that one is heading for death.

They mainly carry out accurate fixed-point attacks according to the characteristics of services, such as CC of the Web, retrieval of data services, download of file services, etc. Such attacks are often not aimed at congesting traffic channels or protocol processing channels. They are busy situations in which the server always handles high-consumption services and thus cannot respond to normal services. The detailed schematic diagram is as follows:
