Kevin, a security team member, was instructed to share a policy document with the employees. As it was supposed to be shared within the network, he used a simple algorithm to encrypt the document that just rearranges the same characters to produce the ciphertext.
Identify the type of cipher employed by Kevin in the above scenario.
Correct : A
Atransposition cipherrearranges characters or bits of plaintext to produce ciphertext. In Kevin's scenario, he used an algorithm that rearranges the same characters to create the ciphertext. This aligns with the characteristics of a transposition cipher, where the order of characters is altered without changing their identity.

Jack, a forensic investigator, was appointed to investigate a Windows-based security incident. In this process, he employed an Autopsy tool to recover the deleted files from unallocated space, which helps in gathering potential evidence.
Which of the following functions of Autopsy helped Jack recover the deleted files?
Correct : C
Comprehensive Explanation: TheAutopsytool is a digital forensics platform that assists investigators in analyzing and recovering evidence from various sources. One of its crucial functions isdata carving. Here's how it works:
Data Carving:
Data carving, also known asfile carving, is a technique used to retrieve files from unallocated space on storage devices.
When files are deleted, they may not be immediately overwritten. Instead, their remnants remain in unallocated areas of the storage medium.
Autopsy'sPhotoRec Carver moduleperforms data carving by scanning unallocated space, identifying file signatures, and recovering deleted files.
These files are often found in seemingly ''empty'' portions of the device storage.
By analyzing unallocated space, Autopsy can uncover potential evidence that was previously deleted.

Wesley, a fitness freak, purchased a new Apple smartwatch and synced it with a mobile app downloaded from an unauthorized third party. At the end of the day, when Wesley attempted to access his fitness report from the app, it generated an unusual report and asked for some unnecessary permissions to view it.
Which of the following mobile risks is demonstrated in the above scenario?
Correct : B
In this scenario, Wesley's use of an unauthorized third-party mobile app to sync with his Apple smartwatch highlights the risk ofimproper platform usage. Here's why:
Unauthorized Third-Party App: Wesley downloaded the app from an unauthorized source, which means it hasn't undergone proper security checks or vetting. Such apps may contain vulnerabilities or malicious code.
Unusual Report and Unnecessary Permissions: The app generated an unusual fitness report and requested unnecessary permissions. This behavior indicates that the app is not following proper guidelines for platform usage.
Platform Security Guidelines: Mobile platforms (like iOS or Android) have specific guidelines for app development and usage. When users sideload apps from untrusted sources, they bypass these guidelines, risking security and privacy.
Risk Implications:
Data Privacy: Unauthorized apps may mishandle sensitive data (like fitness reports), leading to privacy breaches.
Malware or Spyware: The app could contain malicious code, potentially compromising the device or user data.
Permissions Abuse: Requesting unnecessary permissions can lead to data leakage or unauthorized access.
