We will use a tool called HPING3 for performing syn flood. The attacker sends a flood of malicious data packets to a target system. A SYN Flood is analogous to a worker in a supply room receiving requests from the front of the store. An attacker can launch a DOS attack by flooding a host with thousands of TCP SYN packets, the source address would be spoofed with no way for the host server to respond, this would create half-open TCP connections on the host consuming resources until the host is overwhelmed and packets are dropped. This is how you perform a simple Syn flood attack!

The intent is to overload the target and stop it working as it should. Unlike other types of DDoS attacks, SYN flood DDoS attacks are not intending to use up all of the host’s memory, but rather, to exhaust the reserve of open connections connected to a port, from individual and often phony IP addresses. You signed in with another tab or window. Successful attacks left the system wide open for root access from anywhere on the Internet. A SYN Flood occurs when the TCP layer is saturated, preventing the completion of the TCP three-way handshake between client and server on every port. Does anyone know another tool?
