In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.

In the process of DNS resolution, the client initiates a query request, and the DNS server may need to make additional queries to complete the resolution process and give a response, which will consume certain computing and network resources. If an attacker uses a large number of controlled hosts to continuously send resolution requests for different domain names, the cache of the DNS server will be continuously refreshed, and the failure of a large number of resolution requests to hit the cache will cause the DNS server to consume additional resources for iterative queries, which will greatly increase the resource consumption of the DNS server.
