Certified Ethical Hacker (CEH v11) — Question 195

To create a botnet, the attacker can use several techniques to scan vulnerable machines. The attacker first collects information about a large number of vulnerable machines to create a list. Subsequently, they infect the machines. The list is divided by assigning half of the list to the newly compromised machines.
The scanning process runs simultaneously. This technique ensures the spreading and installation of malicious code in little time.
Which technique is discussed here?

Answer options

• A. Subnet scanning technique
• B. Permutation scanning technique
• C. Hit-list scanning technique.
• D. Topological scanning technique

Correct answer: C

Explanation

The correct answer is C, Hit-list scanning technique, as it involves creating a targeted list of compromised machines for swift infection. The other options, such as Subnet, Permutation, and Topological scanning techniques, refer to different methodologies for network scanning and do not specifically focus on the concept of using a pre-compiled list of targets.
