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.

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
To further enumerate users on a Windows machine using native operating system commands, the tester should use net.exe commands. The net command is a versatile tool that provides various network functionalities, including user enumeration.
✑ net.exe: net user
✑ uk.co.certification.simulator.questionpool.PList@5192aa65 net localgroup administrators
✑ Enumerating Users:
✑ Pentest References:
Using net.exe commands, the penetration tester can effectively enumerate user accounts and group memberships on the compromised Windows machine, aiding in further exploitation and privilege escalation.

During a security assessment, a penetration tester needs to exploit a vulnerability in a wireless network's authentication mechanism to gain unauthorized access to the network. Which of the following attacks would the tester most likely perform to gain access?
Correct Answer:
A
To exploit a vulnerability in a wireless network's authentication mechanism and gain unauthorized access, the penetration tester would most likely perform a KARMA attack.
✑ KARMA Attack:
✑ Purpose:
✑ Other Options:
Pentest References:
✑ Wireless Security Assessments: Understanding common attack techniques such as KARMA is crucial for identifying and exploiting vulnerabilities in wireless networks.
✑ Rogue Access Points: Setting up rogue APs to capture credentials or perform man-in-the-middle attacks is a common tactic in wireless penetration testing.
By performing a KARMA attack, the penetration tester can exploit the wireless network's authentication mechanism and gain unauthorized access to the network.
