A penetration tester is conducting an assessment against a group of publicly available web servers and notices a number of TCP resets returning from one of the web servers. Which of the following is MOST likely causing the TCP resets to occur during the assessment?
Correct Answer:
A
A Web Application Firewall (WAF) is designed to monitor, filter or block traffic to a web application. A WAF will monitor incoming and outgoing traffic from a web application and is often used to protect web servers from attacks such as SQL Injection, Cross-Site Scripting (XSS), and other forms of attacks. If a WAF detects an attack, it will often reset the TCP connection, causing the connection to be terminated. As a result, a penetration tester may see TCP resets when a WAF is present. Therefore, the most likely reason for the TCP resets returning from the web server is that the web server is using a WAF.
A penetration tester is testing a new version of a mobile application in a sandbox environment. To intercept and decrypt the traffic between the application and the external API, the tester has created a private root CA and issued a certificate from it. Even though the tester installed the root CA into the trusted stone of the smartphone used for the tests, the application shows an error indicating a certificate mismatch and does not connect to the server. Which of the following is the
MOST likely reason for the error?
Correct Answer:
D

Penetration tester who was exclusively authorized to conduct a physical assessment noticed there were no cameras pointed at the dumpster for company. The penetration tester returned at night and collected garbage that contained receipts for recently purchased networking :. The models of equipment purchased are vulnerable to attack. Which of the following is the most likely next step for the penetration?
Correct Answer:
C
The most likely next step for the penetration tester is to scan the equipment and verify the findings, which is a process of using tools or techniques to probe or test the target equipment for vulnerabilities or weaknesses that can be exploited. Scanning and verifying the findings can help the penetration tester confirm that the models of equipment purchased are vulnerable to attack, and identify the specific vulnerabilities or exploits that affect them. Scanning and verifying the findings can also help the penetration tester prepare for the next steps of the assessment, such as exploiting or reporting the vulnerabilities. Scanning and verifying the findings can be done by using tools such as Nmap, which can scan hosts and networks for ports, services, versions, OS, or other information1, or Metasploit, which can exploit hosts and networks using various payloads or modules2. The other options are not likely next steps for the penetration tester. Alerting the target company of the discovered information is not a next step, but rather a final step, that involves reporting the findings and recommendations to the client after completing the assessment. Verifying the discovered information with the manufacturer is not a next step, as it may not provide accurate or reliable information about the vulnerabilities or exploits that affect the equipment, and it may also alert the manufacturer or the client of the assessment. Returning to the dumpster for more information is not a next step, as it may not yield any more useful or relevant information than what was already collected from the receipts.
