Question 1:
Daniel, a skilled hacker, set his sights on CyberNet Corp., a multinational corporation. He opted to identify the IoT devices connected within the target network utilizing default credentials, susceptible to various hijacking attacks. To achieve this, he employed an automated tool to conduct a thorough scan of the target network, focusing on specific types of IoT devices. The objective was to ascertain if these devices were utilizing the default, factory-set credentials.
What is the tool utilized by Daniel in the above scenario?
A. AT&T IoT Platform
B. Azure IoT Central
C. IoTSeeker
D. IoT Inspector
Answer: C
Explanation:
The most likely tool utilized by Daniel in the scenario is IoTSeeker.
Here‘s why:
Functionality: IoTSeeker specifically focuses on identifying vulnerable IoT devices within networks. It scans for specific device types and known default credentials, matching Daniel‘s objective.
Open-source: IoTSeeker is an open-source tool, readily available for download and use by anyone, making it a viable choice for a hacker like Daniel.
Automation: IoTSeeker offers automated scanning capabilities, allowing Daniel to efficiently scan the entire target network without manual effort.
Wide Coverage: It supports a broad range of IoT device types and protocols, increasing the chances of detecting susceptible devices within CyberNet Corp.‘s network.
Why other options are less likely:

AT&T IoT Platform: This is a commercial IoT platform designed for managing connected devices, not for security scanning or vulnerability detection.
Azure IoT Central: Similar to AT&T‘s platform, Azure IoT Central is a cloud-based service for managing and monitoring IoT devices, not a security scanning tool.
Question 2:
What strategy involves the use of malicious code to reroute users‘ web traffic?
A. Spear-phishing
B. Spimming
C. Phishing
D. Pharming
Answer: D
Explanation:
Pharming:
Pharming is a cyber attack where attackers use malicious code or other means to redirect users‘ web traffic to fraudulent websites, often without the users‘ knowledge.
The goal of pharming is to trick users into visiting fake websites that may look identical to legitimate ones. Attackers can then capture sensitive information such as login credentials, personal details, or financial information.
Other Options:
Spear-phishing: Spear-phishing is a targeted form of phishing where attackers tailor their deceptive messages to specific individuals or organizations. While it involves tricking users, it doesn‘t inherently involve redirecting web traffic.
Phishing: Phishing is a broader term that refers to deceptive attempts to trick individuals into revealing sensitive information by posing as a trustworthy entity. Like spear-phishing, it doesn‘t necessarily involve redirecting web traffic.
Spimming: Spimming is a term that combines “spam“ and “instant messaging.“ It refers to spamming through instant messaging systems. This option is unrelated to the strategy of redirecting web traffic.
Question 3:
In what type of attack is the goal to overflow the content-addressable memory (CAM) table within an Ethernet switch?
A. MAC flooding
B. DDoS attack
C. Evil twin attack
D. DNS cache flooding
Answer: A
Explanation:
In a MAC flooding attack, the goal is to overflow the content-addressable memory (CAM) table within an Ethernet switch. Here‘s an explanation:
Ethernet switches use a CAM table to keep track of the association between MAC addresses and the corresponding switch ports. When a device sends a frame to the switch, the switch learns the source MAC address and the corresponding port by updating its CAM table. This information is then used to forward frames only to the appropriate port, improving network efficiency.
During a MAC flooding attack:
1. Excessive MAC Addresses: The attacker sends a large number of Ethernet frames to the switch, each containing a different source MAC address. The intention is to flood the switch with a multitude of MAC addresses.
2. CAM Table Overflow: The CAM table in the switch has a limited capacity. As the attacker sends numerous frames with different MAC addresses, the CAM table becomes full, and the switch can no longer accommodate new entries.
3. Switch Behavior: When the CAM table is full, the switch enters a fail-open state. In this state, it behaves like a hub, forwarding incoming frames to all ports instead of selectively forwarding them based on the MAC address information. This essentially turns the switch into a less efficient, hub-like device.
4. Traffic Sniffing: The attacker can now capture a significant amount of network traffic by sniffing the frames that are forwarded to all ports. This can include sensitive information, leading to potential security breaches.
Why other options are incorrect:
DDoS attack: While a DDoS attack can overwhelm network resources, it doesn‘t specifically target the CAM table.
Evil twin attack: This involves creating a fake Wi-Fi hotspot to intercept traffic, not Ethernet switches.
DNS cache flooding: This targets DNS servers, not Ethernet switches.
Question 4:
A financial organization stores and processes sensitive privacy information related to property loans. However, auditing has never been enabled on the system.
What is the first step that the bank should take before enabling the audit feature?
A. Allocate funds for staffing of audit log review
B. Determine the impact of enabling the audit feature
C. Perform a cost/benefit analysis of the audit feature
D. Perform a vulnerability scan of he system
Answer: B
Explanation:
Determine the impact of enabling the audit feature
Understanding the potential impact involves considering factors such as system performance, resource utilization, and any potential disruptions that may occur when audit logging is activated. This step helps ensure that enabling the audit feature does not negatively affect the normal operation of the system.
Once the impact is assessed, the bank can proceed with other necessary steps, such as allocating funds for staffing, performing a vulnerability scan, and conducting a cost/benefit analysis. However, understanding the impact is crucial to make informed decisions and mitigate any potential risks associated with enabling audit logging.
Question 5:

Richard conducted an analysis of the compromised device, extracting details of the incident, including the nature of the attack, its severity, target, impact, propagation method, and exploited vulnerabilities.
During which phase of Incident Handling and Response (IH&R) did Richard identify and address these issues?
A. Incident triage
B. Preparation
C. Incident recording and assignment
D. Eradication
Answer: A
Explanation:
Incident Triage:
Incident triage involves the initial investigation and analysis of the incident to determine its severity, scope, and potential impact.
The incident response team identifies the type of incident, the systems affected, and the potential damage during this phase.
Once triaged, the incident is assigned to an appropriate team or individual for further investigation and response.

Question 6:
A malicious actor opted to compromise the passwords utilized in industrial control systems. In this endeavor, the attacker implemented a looping strategy to unveil these passwords. The approach involved checking one character at a time to determine if the first character input was accurate. If the initial character was correct, the attacker persisted in the loop to assess consecutive characters; otherwise, the loop was terminated. Additionally, the attacker assessed the time taken by the system to complete a full password authentication process, allowing inference regarding the number of correctly entered characters.
What is the attack technique utilized by the attacker to decipher the passwords of the industrial control systems?
A. HMI-based attack
B. Side-channel attack
C. Denial-of-service attack
D. Buffer overflow attack
Answer: B
Explanation:
Side-channel attack:
In a side-channel attack, an attacker exploits information leaked through unintended channels, such as the time taken to perform a computation or the power consumption during an operation.
In this scenario, the attacker focuses on the timing side channel. By carefully measuring the time the system takes to complete a full password authentication process, the attacker can infer information about the correctness of individual characters in the password.
The looping strategy, checking one character at a time and terminating the loop if an incorrect character is identified, allows the attacker to deduce the correct characters in a sequential manner.
The timing information provides insight into how long the system takes to process correct characters, helping the attacker piece together the password over successive iterations.
In contrast to the other options:
Buffer overflow attack: This involves exploiting vulnerabilities in a program‘s buffer handling, leading to unintended code execution. It is not the technique described in the scenario.
Denial-of-service attack: This type of attack aims to disrupt the normal functioning of a system or network, typically by overwhelming it with excessive requests. The scenario does not describe a denial-of-service attack.
HMI-based attack (Human-Machine Interface): This refers to attacks targeting the interface through which humans interact with machines. The scenario does not involve manipulating the human-machine interface; instead, it focuses on exploiting timing information during the password authentication process.
Question 7:
A cybersecurity firm was contracted by a small healthcare provider to conduct a technical assessment of its network. What is the optimal method for identifying vulnerabilities on a Windows-based system?
A. Check MITRE.org for the latest list of CVE findings
B. Use a scan tool like Nessus
C. Create a disk image of a clean Windows installation
D. Use the built-in Windows Update tool
Answer: B
Explanation:
Using a scan tool like Nessus is an effective method for discovering vulnerabilities on a Windows-based computer. Nessus is widely used for vulnerability scanning and can identify a range of security issues within the system.
Using the built-in Windows Update tool is important for keeping the system up-to-date with the latest security patches. However, it primarily focuses on updating the operating system and Microsoft applications rather than actively identifying vulnerabilities.
Checking MITRE.org for the latest list of CVE (Common Vulnerabilities and Exposures) findings is a valuable resource, but it may not actively scan the system for vulnerabilities. MITRE provides information about known vulnerabilities but does not perform real-time scanning.
Creating a disk image of a clean Windows installation is useful for backup and recovery purposes, but it doesn‘t actively identify vulnerabilities. It is more focused on system restoration.
