What characterizes a Smurf attack?

• A. Exploiting weak passwords
• B. Overloading a target with ICMP requests
• C. Guessing encryption keys
• D. Stealing data via malware

Answer: (B)

A Smurf attack is characterized by overloading a target with ICMP (Internet Control Message Protocol) requests. This type of denial-of-service attack aims to flood a network with traffic, making it unable to respond to legitimate requests. In a typical Smurf attack, the attacker sends a large number of ICMP echo request packets (ping requests) to a network's broadcast address using a spoofed IP address, which is the address of the intended target. Because many devices on the network respond to the broadcast, this results in a massive amount of traffic being sent to the victim's IP address, ultimately overwhelming the target's resources and causing a denial of service. The focus on ICMP requests is crucial, as it underscores the method of the attack, distinguishing it from other types of exploits that might utilize different protocols or tactics.
