Ethical Hacking Essentials Practice Test

Which type of attack did Simon perform to tamper with the transmission between IoT devices?

1. Man-in-the-middle attack

2. Replay attack

3. Cryptanalysis attack

4. Brute-force attack

The correct answer is: Cryptanalysis attack

The correct type of attack that Simon performed to tamper with the transmission between IoT devices is a man-in-the-middle attack. This type of attack involves an attacker intercepting and potentially altering the communication between two parties who believe they are directly communicating with each other. In the context of IoT devices, a man-in-the-middle attack allows the attacker to access and manipulate the data being sent or received, which can lead to unauthorized control or data theft. A replay attack, in contrast, involves capturing a transmission and sending it again (or replaying it) to trick the receiver into believing it's a legitimate transaction. This is different from tampering since it doesn't necessarily involve altering the communication. Cryptanalysis attack refers to the process of breaking encryption codes to access the original data. While this can be related to securing the communication of IoT devices, it doesn't specifically address tampering with ongoing transmissions. A brute-force attack focuses on trying numerous combinations to crack passwords or encryption keys, which is a different approach altogether and does not involve intercepting or altering ongoing communications. Understanding these attack types is essential for recognizing how vulnerabilities in IoT devices can be exploited, particularly through methods like the man-in-the-middle attack, which allows for ongoing tampering of transmissions.
