EC-Council ECSS Exam - Topic 1 Question 117 Discussion

Martin, a hacker, aimed to crash a target system. For this purpose, he spoofed the source IP address with the target's IP address and sent many ICMP ECHO request packets to an IP broadcast network, causing all the hosts to respond to the received ICMP ECHO requests and ultimately crashing the target machine.Identify the type of attack performed by Martin in the above scenario.
C) Smurf attack
A) UDP flood attack
B) Multi vector attack
D) Fragmentation attack

Martin, a hacker, aimed to crash a target system. For this purpose, he spoofed the source IP address with the target's IP address and sent many ICMP ECHO request packets to an IP broadcast network, causing all the hosts to respond to the received ICMP ECHO requests and ultimately crashing the target machine.

Identify the type of attack performed by Martin in the above scenario.

Show Suggested Answer Hide Answer
Suggested Answer: C

In the scenario described, Martin conducted a Smurf attack. This type of attack involves spoofing the source IP address with the target's IP address and sending ICMP ECHO request packets to an IP broadcast network. The broadcast network then amplifies the traffic by directing it to all hosts, which respond to the ICMP ECHO requests. This flood of responses is sent back to the spoofed source IP address, which is the target system, leading to its overload and potential crash.The Smurf attack is a type of distributed denial-of-service (DDoS) attack that exploits the vulnerabilities of the Internet Protocol (IP) and the Internet Control Message Protocol (ICMP).Reference: EC-Council Certified Security Specialist (E|CSS) course materials and documents

Definitely Smurf attack. It overwhelms the target with responses.

I think it's a Smurf attack. The IP spoofing fits.

Wait, can you really crash a system like that? Seems too easy!

Totally agree, it's a classic example of a Smurf attack.

I thought it was a UDP flood attack at first.

I definitely recall that a Smurf attack involves sending ICMP packets with a spoofed IP. So, I think the answer is C.

I’m a bit confused. I thought a UDP flood attack was similar, but this seems more like it involves ICMP.

I remember practicing a question about IP spoofing and broadcast networks. This sounds like the Smurf attack since it uses ICMP ECHO requests.

I think this is related to a denial-of-service attack, but I'm not sure if it's specifically a Smurf attack or something else.
