Question 667
At Apex Financial Services in Houston, Texas, ethical hacker Javier Ruiz evaluates mobile security practices under the company's BYOD policy. He demonstrates that employees often install applications that request access to contact lists, cameras, and messaging services, even though these functions are unrelated to the apps' intended purpose. This behavior allows a malicious program to harvest sensitive corporate information. Which security guideline would most directly prevent this issue?
Correct Answer: C
The issue described is excessive or inappropriate application permission granting in a BYOD environment. Employees install apps that request access to sensitive device resources-contacts, camera, messaging- despite those permissions not being necessary for the app's stated purpose. This creates a risk of data harvesting and corporate information leakage if a malicious or overly intrusive app is installed. The most direct guideline to prevent this behavior is to review the permissions requested by apps before installing them. Mobile operating systems rely heavily on permission models to control access to sensitive data and device capabilities. When users approve broad permissions without scrutiny, they effectively authorize the app to collect and transmit sensitive information. Enforcing a culture and policy of checking permissions (and denying or uninstalling apps that request unnecessary access) directly addresses the root cause in the scenario: user consent enabling excessive privilege at the app level. In a corporate BYOD program, this guideline is often paired with mobile security controls such as enterprise app stores, allowlists/denylists, MDM/MAM policies, and user awareness training, but the question asks for the most direct preventive guideline. Why the other options are less direct: Encryption at rest (A) helps protect stored data if the device is lost or compromised, but it does not stop an authorized app from accessing data via granted permissions. Automatic locking/biometrics (B) reduces unauthorized physical access, but it does not constrain what a permitted app can access while the device is in use. App passwords (D) can help restrict casual access to an app, but they do not solve the problem of an app legitimately being granted invasive permissions. Therefore, the best answer is C. Review permissions requested by apps before installing them.
Question 668
A digital forensics consultant in Portland, Oregon examines an iPhone seized as part of a corporate data leakage investigation. The device contains third-party extensions and system modifications not typically permitted by the operating system vendor. The owner explains that whenever the device is powered off and restarted, it boots normally and remains fully functional for everyday tasks such as calls and messaging. However, the custom extensions and system-level tweaks do not function until a specific jailbreak application installed on the device is manually executed. No external computer is required during this reactivation process. Determine the type of jailbreaking technique implemented on this device.
Correct Answer: D
The correct answer is D. Semi-Untethered Jailbreaking. The key details are: The device boots normally after restart. Basic phone functions continue to work. The jailbreak modifications do not become active automatically after reboot. The user must manually run a jailbreak application on the device. No external computer is required. This behavior is best classified as semi-untethered jailbreaking. In a semi-untethered jailbreak, the device can reboot and operate normally, but the jailbreak state must be re-enabled by running an installed jailbreak application on the device itself. CEH-aligned mobile hacking material explains that in tethered jailbreaking, rebooting removes jailbreak patches and a computer is required to boot or re-jailbreak the device. It also explains that in untethered jailbreaking, the device remains jailbroken after reboot without needing a computer. Semi-tethered jailbreaking is described as a middle state where the device can complete startup and normal functions, but modifications require the jailbreak tool to restore the patched state . The "no external computer required; run the installed jailbreak app" condition makes the best modern classification semi-untethered. Option A. Untethered Jailbreaking is incorrect because the jailbreak does not remain active automatically after reboot. Option B. Tethered Jailbreaking is incorrect because no external computer is required and the phone does not become stuck during startup. Option C. Semi-Tethered Jailbreaking is close, but semi-tethered commonly implies that a computer or external tool may be needed to restore the jailbroken state. The question specifically says the installed jailbreak app on the device is manually executed without a computer. Option D. Semi-Untethered Jailbreaking is correct because the device boots normally, but the jailbreak must be reactivated locally through an installed app. Therefore, the best answer is D. Semi-Untethered Jailbreaking.
Question 669
Johnson, an attacker, performed online research for the contact details of reputed cybersecurity firms. He found the contact number of sibertech.org and dialed the number, claiming himself to represent a technical support team from a vendor. He warned that a specific server is about to be compromised and requested sibertech.org to follow the provided instructions. Consequently, he prompted the victim to execute unusual commands and install malicious files, which were then used to collect and pass critical Information to Johnson's machine. What is the social engineering technique Steve employed in the above scenario?
Correct Answer: A
https://www.eccouncil.org/what-is-social-engineering/ This Social Engineering scam involves an exchange of information that can benefit both the victim and the trickster. Scammers would make the prey believe that a fair exchange will be present between both sides, but in reality, only the fraudster stands to benefit, leaving the victim hanging on to nothing. An example of a Quid Pro Quo is a scammer pretending to be an IT support technician. The con artist asks for the login credentials of the company's computer saying that the company is going to receive technical support in return. Once the victim has provided the credentials, the scammer now has control over the company's computer and may possibly load malware or steal personal information that can be a motive to commit identity theft. "A quid pro quo attack (aka something for something" attack) is a variant of baiting. Instead of baiting a target with the promise of a good, a quid pro quo attack promises a service or a benefit based on the execution of a specific action." https://resources.infosecinstitute.com/topic/common-social-engineering-attacks/#:~: text=A%20quid%20pro%20quo%20attack,execution%20of%20a%20specific%20action.
Question 670
During an authorized security assessment of a smart thermostat manufacturer in Denver, Colorado, a certified ethical hacker receives a firmware image extracted from a production device for further evaluation. The tester begins by examining the binary file to determine its format and architecture. Basic inspection commands are executed against the image to review embedded human-readable content and observe low-level binary structure before proceeding with deeper analysis. Within the firmware analysis workflow, which stage is the tester performing?
Correct Answer: C
The correct answer is C. Analyze Firmware. The firmware image has already been obtained. The tester is now inspecting the binary to understand its format, architecture, readable strings, and low-level structure. This is part of the Analyze Firmware stage. The referenced firmware analysis material lists commands such as file < bin > , strings, strings -n5 < bin > , strings -tx < bin > , binwalk < bin > , and hexdump -C < bin > as firmware analysis activities used to inspect firmware content and structure . Option A. Extract the Filesystem is incorrect because filesystem extraction would involve extracting embedded filesystems from the firmware image, commonly with tools such as binwalk -e. Option B. Obtain Firmware is incorrect because the question states that the tester already received the firmware image. Option D. Emulate Firmware is incorrect because emulation involves running or simulating the firmware environment, which has not yet occurred. Therefore, the best answer is C. Analyze Firmware.
