Which type of attack sends packets to exploit broadcast networks?

The correct answer is Smurf Attack because it specifically targets broadcast networks by using Internet Control Message Protocol (ICMP) packets. In a Smurf Attack, the attacker sends ICMP echo request packets (pings) to a network's broadcast address, which results in all devices on that network responding to the request. This amplifies the traffic directed at the targeted victim, leading to a denial-of-service condition.

The unique characteristic of a Smurf Attack lies in its ability to leverage the broadcast capability of networks, where a single packet can result in multiple responses, thereby overwhelming a target with a massive influx of data. This behavior exploits the fundamental functionality of how broadcast networks operate, making it particularly damaging when deployed against them.

In contrast, the other options do not exploit broadcast networks in the same way. For instance, a Ping Flood is a type of denial-of-service attack that inundates a target with ICMP echo request packets, but it does not use broadcasts or amplify the responses by leveraging others on the network. Ransomware involves malicious software that encrypts data for extortion, and a Rootkit is a set of tools used to gain unauthorized access and control over a computer while concealing its presence. Thus, the Smurf Attack
