問題 #79
A cybercriminal hacked into an Apple iPad that belongs to a company's chief executive officer (CEO). The cybercriminal deleted some important files on the data volume that must be retrieved.
Which hidden folder will contain the digital evidence?
答案:A
解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
On Apple iOS devices, deleted files are often moved to a hidden Trash folder before permanent deletion. The directory/.Trashes/501is a hidden folder where deleted files for user ID 501 (the first user created on macOS
/iOS devices) are temporarily stored.
* This folder can contain files marked for deletion and thus is a prime location for recovery attempts.
* /lost+foundis a directory commonly used on Unix/Linux file systems for recovered file fragments after file system corruption but is not the default trash location on iOS.
* /Private/etcand/etccontain system configuration files, not deleted user files.
Reference:Apple forensic investigations per NIST and training manuals such as those from Cellebrite and BlackBag Technologies indicate that user-deleted files on iOS devices reside in.Trashesor similar hidden directories until permanently removed.
問題 #80
Which universal principle must be observed when handling digital evidence?
答案:B
解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
The foremost principle in digital forensics isnever altering the original evidence. This ensures integrity, authenticity, and admissibility in court.
* Investigators analyze forensic copies, not originals.
* Write-blockers and hashing are used to prevent changes.
* Any alteration-intentional or accidental-can invalidate evidence.
Reference:NIST SP 800-86 and SP 800-101 define the unaltered preservation of evidence as the first and most essential forensic rule.
問題 #81
An organization believes that a company-owned mobile phone has been compromised.
Which software should be used to collect an image of the phone as digital evidence?
答案:B
解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
Forensic Toolkit (FTK) is a widely recognized and trusted software suite in digital forensics used to acquire and analyze forensic images of devices, including mobile phones. FTK supports the creation of bit-by-bit images of digital evidence, ensuring the integrity and admissibility of the evidence in legal contexts. This imaging process is crucial in preserving the original state of the device data without alteration.
* FTK enables forensic investigators to perform logical and physical acquisitions of mobile devices.
* It maintains the integrity of the evidence by generating cryptographic hash values (MD5, SHA-1) to prove that the image is an exact copy.
* Other options such as PTFinder or Forensic SIM Cloner focus on specific tasks like SIM card cloning or targeted data extraction but do not provide full forensic imaging capabilities.
* Data Doctor is more aligned with data recovery rather than forensic imaging.
Reference:According to standard digital forensics methodologies outlined by NIST Special Publication 800-
101(Guidelines on Mobile Device Forensics) and the SANS Institute Digital Forensics and Incident Response guides, forensic tools used to acquire mobile device images must be capable of bit-stream copying with hash verification, which FTK provides.
問題 #82
An employee is suspected of using a company Apple iPhone 4 for inappropriate activities.
Which utility should the company use to access the iPhone without knowing the passcode?
答案:C
解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
Device Seizure is a specialized mobile forensic acquisition tool capable of extracting data from locked mobile devices, including older Apple iPhone models such as the iPhone 4. It supports physical and logical acquisition, bypassing certain lock restrictions depending on model and OS version.
* Device Seizure is widely used in law enforcement mobile forensics.
* FTK is primarily a computer forensics suite, not designed for bypassing mobile passcodes.
* Data Doctor does not support advanced mobile device extraction.
Reference:NIST mobile forensics guidelines and approved forensic tool references list Device Seizure as a tool capable of acquiring data from locked mobile devices.
問題 #83
Where does Windows store passwords for local user accounts?
答案:D
解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
Windows stores the hashes of local user account passwords in the SAM (Security Account Manager) file, which is located in theWindowsSystem32configdirectory. This file is a critical component in the Windows security infrastructure.
* The registry paths in A and B refer to network profiles and wireless configuration data, unrelated to password storage.
* The "Security" file also resides in theSystem32configfolder but stores security policy data rather than password hashes.
* The SAM file stores password hashes and is targeted in forensic investigations for credential recovery.
Reference:Microsoft technical documentation and NIST digital forensics standards explain that the SAM file is the definitive source for local user password hashes in Windows systems.
