CompTIA PT0-002 Exam Practice Questions (P. 3)

GPT-4o - Answer

To effectively confirm a true positive finding from a vulnerability scan, a manual testing approach is essential. Engaging directly with the suspected vulnerability allows a penetration tester to thoroughly explore and understand its mechanics and impacts. This hands-on methodology isn’t just about confirming the presence of the vulnerability; it also provides insight into its exploitability, helping to validate the findings beyond automated tools which might only offer an initial indication. Thus, manual testing isn’t just a verification step—it’s a deeper dive to ensure comprehensive security assessment.

Let's consider the scenario detailed in the question: the timeframe is crucial here. Effective penetration testing must consider both efficiency and stealth. Brute-forcing, contrary to what might be initially thought, can be surprisingly quick for weaker passwords and potentially optimized with advanced tools like GPU acceleration. However, the pointed out comment rightly emphasizes the practical risks and limitations involved in brute forcing within an eight-hour window, especially against robust external defenses. It's suggested that spear phishing, as a more strategic approach leveraging the human factor, could likely offer a higher probability of success. This contrasts with brute-force attempts, which could too easily trigger security protocols or prove futile against more complex passwords within the given timeframe. Therefore, balancing against the possible infeasibility of a brute-force attack comfortably within eight hours, one should also consider the likely effectiveness of spear phishing under these constraints.

Scapy is indeed the more suitable tool for the task described in the question. It excels in creating and manipulating network packets, including crafting specific DNS responses necessary for conducting on-path attacks. This powerful packet manipulation utility enables precise control over packet contents, making it ideal for scenarios where a penetration tester needs to craft and send custom DNS query responses back to a target host, effectively facilitating network-based attacks and tests.
