Certified Ethical Hacker (CEH v13) — Question 3

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, as the hit-list scanning technique involves compiling a list of vulnerable machines and using already compromised systems to scan and infect others. Options A, B, and D describe different scanning methods that do not specifically involve the use of a pre-compiled list for spreading malware quickly.
