Compared with resource consumption attacks, service consumption attacks do not require too much traffic. 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:Feedback weaponizationDuring the establishment of a tcp connection, If the server returns syn and ack messages, The client does not confirm it for some reason. This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout.

The half-open connection will be kept in the connection table of the server until the connection is disconnected.2017-02-01 10:35:34　　二零二零年，团队为嫦娥五号开发了「表面采样及初级封装系统」，火箭升空当晚，离开了的伙伴也回来，跟于杰和张宁一同见证历史时刻…Any feedback mechanism will be weaponized to attack legitimate users and content./surrender
