Certified Ethical Hacker (CEH v13) — Question 22

John, a disgruntled ex-employee of an organization, contacted a professional hacker to exploit the organization. In the attack process, the professional hacker installed a scanner on a machine belonging to one of the victims and scanned several machines on the same network to identify vulnerabilities to perform further exploitation.
What is the type of vulnerability assessment tool employed by John in the above scenario?

Answer options

• A. Agent-based scanner
• B. Network-based scanner
• C. Cluster scanner
• D. Proxy scanner

Correct answer: B

Explanation

The correct answer is B, Network-based scanner, as it is specifically designed to scan multiple devices across a network for vulnerabilities. The other options, such as Agent-based scanner, focus on individual machines, while Cluster scanner and Proxy scanner are not relevant to the context of network-wide scanning.
