A penetration tester gains access to a Windows machine and wants to further enumerate users with native operating system credentials. Which of the following should the tester use?
Correct Answer:
C
The net.exe commands are native to the Windows operating system and are used to manage and enumerate network resources, including user accounts.

A penetration tester needs to evaluate the order in which the next systems will be selected for testing. Given the following output:
Hostname | IP address | CVSS 2.0 | EPSS hrdatabase | 192.168.20.55 | 9.9 | 0.50
financesite | 192.168.15.99 | 8.0 | 0.01
legaldatabase | 192.168.10.2 | 8.2 | 0.60
fileserver | 192.168.125.7 | 7.6 | 0.90
Which of the following targets should the tester select next?
Correct Answer:
A
Given the output, the penetration tester should select the fileserver as the next target for testing, considering both CVSS and EPSS scores. Explanation
✑ CVSS (Common Vulnerability Scoring System):
✑ EPSS (Exploit Prediction Scoring System):
✑ Evaluation:
Pentest References:
✑ Prioritization: Balancing between severity (CVSS) and exploitability (EPSS) is crucial for effective vulnerability management.
✑ Risk Assessment: Evaluating both the impact and the likelihood of exploitation helps in making informed decisions about testing priorities.
By selecting the fileserver, which has a high EPSS score, the penetration tester focuses on a target that is more likely to be exploited, thereby addressing the most immediate risk.

A penetration tester is authorized to perform a DoS attack against a host on a network. Given the following input:
ip = IP("192.168.50.2")
tcp = TCP(sport=RandShort(), dport=80, flags="S") raw = RAW(b"X"*1024)
p = ip/tcp/raw
send(p, loop=1, verbose=0)
Which of the following attack types is most likely being used in the test?
Correct Answer:
D
A SYN flood attack exploits the TCP handshake by sending a succession of SYN requests to a target's system. Each request initializes a connection that the target system must acknowledge, thus consuming resources.

During a penetration test, the tester uses a vulnerability scanner to collect information about any possible vulnerabilities that could be used to compromise the network. The tester receives the results and then executes the following command:
snmpwalk -v 2c -c public 192.168.1.23
Which of the following is the tester trying to do based on the command they used?
Correct Answer:
D
The command snmpwalk -v 2c -c public 192.168.1.23 is used to query SNMP (Simple Network Management Protocol) data from a device. Here??s the purpose in the context provided:
✑ SNMP Enumeration:
✑ Purpose of the Command:
✑ Comparison with Other Options:
By using snmpwalk, the tester is validating the results from the vulnerability scanner and removing any false positives, ensuring accurate reporting.

A penetration tester needs to identify all vulnerable input fields on a customer website. Which of the following tools would be best suited to complete this request?
Correct Answer:
A
✑ Dynamic Application Security Testing (DAST):
✑ Advantages of DAST:
✑ Examples of DAST Tools:
Pentest References:
✑ Web Application Testing: Understanding the importance of testing web applications for security vulnerabilities and the role of different testing methodologies.
✑ Security Testing Tools: Familiarity with various security testing tools and their applications in penetration testing.
✑ DAST vs. SAST: Knowing the difference between DAST (dynamic testing) and SAST (static testing) and when to use each method.
By using a DAST tool, the penetration tester can effectively identify all vulnerable input fields on the customer website, ensuring a thorough assessment of the application's security.
