UDP services like echo and chargen can be used together to flood the server, known as a UDP bomb or UDP packet storm.

An attacker can exploit these services to overwhelm the server, leading to unavailability for users.

It is recommended to disable unused UDP services and implement network traffic filters to protect against such attacks.
