A fundamental and universal problem closely related to this aspect is related to the use of open DNS parser to launch DDoS attacks against Switzerland, an anti-spam organization. The open parser does not validate the IP address of the sender of the packet before sending back the DNS reply. Therefore, after the attacker deceives the victim's IP address, he can send a large amount of attack traffic to the victim, and the ratio of attack traffic to request traffic reaches 100: 1. DNS amplification attacks such as these have recently been used by hacker activists, blackmailers and blacklisted website hosts with great success.
自然是后者。

Attackers can use dig query and EDNS0 to carry out efficient DNS amplification attacks. Attackers want the widely existing open DNS parser to send dig query commands, set the udp message size in the opt rr field to a large value, and make the requested source ip address not the target ip address.
DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.
