Which of the following DoS attacks is the hacker attempting to use?
On a target system, a hacker detected UDP protocol problems. The hacker sends a huge number of UDP packets from a machine with a faked IP address, which broadcasts to the network in an attempt to overload the target system with UDP answers.

A Smurf attack

In a Smurf attack, the hacker sends a large number of UDP packets with a spoofed source IP address to a broadcast IP address. The broadcast IP address is an IP address that is configured to send packets to all devices on a network. When the devices on the network receive the UDP packets, they reply to the source IP address, which is the spoofed IP address. This results in the target system being flooded with UDP replies, which can eventually cause it to crash.
