Amplification attack is a special reflection attack. The special feature is that the reflector has the function of amplifying network traffic and is a common technical means in DDoS. Its basic principle is relatively simple. For a C/S service, if the Server-to-Client Response message is larger than the Client-to-Server Request message, the traffic is enlarged. In order to use amplification technology in DDoS, one condition needs to be met, that is, the services provided by Server are based on connectionless protocols such as UDP.
Take synkill. Exe as an example. Run the tool, select the random source address and source port, fill in the target machine address and TCP port, activate the operation, and soon find that the target system is running slowly. If the attack effect is not obvious, it may be that the target machine does not open the filled TCP port or the firewall denies access to the port. At this time, you can select the TCP port that is allowed to access. Generally, Windows systems open ports tcp139 and UNIX systems open ports tcp7, 21, 23, etc.
