質問 # 54
Sarah, a forensic investigator, is working on a criminal case. She was provided with all the suspect devices.
Sarah employs an imaging software tool for duplicating the original data from the suspect devices. However, the tool she employed failed to image the data as the suspect version of the drive was very old and incompatible with imaging software. Hence, Sarah used an alternative data acquisition technique and succeeded in imaging the data.
Which of the following types of data acquisition techniques did Sarah employ in the above scenario?
正解：B
解説：
The key detail is that Sarah'simaging softwarecould not acquire the device because the drive wasvery old and incompatiblewith the software-based approach. In such situations, forensic practice recommends switching to an acquisition method that isless dependent on the operating system or specific imaging application compatibility, while still producing a forensic-accurate duplicate.Bit-stream disk-to-diskacquisition (also called forensic cloning) creates asector-by-sectorcopy of the entire source drive directly onto another physical drive. This method is commonly performed using dedicated duplicators or hardware-assisted workflows that can interface with legacy media more reliably than certain disk-to-image software utilities.
Sparse acquisition would intentionally capture only selected portions of a disk (used to reduce time/storage), which does not fit the goal of "succeeded in imaging the data" after a failure due to incompatibility. Logical acquisition captures only active files/folders through the file system and is not the preferred alternative when full forensic imaging is required, especially in criminal cases. Bit-stream disk-to-image-file is still software
/container dependent and is essentially what failed initially. Therefore, the most appropriate alternative that explains success with an older incompatible drive isBit-stream disk-to-disk (D).

Which of the following file systems is developed by Apple to support Mac OS in its proprietary Macintosh system and replace the Macintosh File System (MFS)?
正解：B
解説：
Apple's original Macintosh computers initially usedMFS (Macintosh File System), which had important limitations, including a relatively flat directory model and constraints that became problematic as storage sizes and file organization needs grew. To address these limitations, Apple introducedHFS (Hierarchical File System)-explicitly designed to replace MFS and provide a truehierarchical directory structure(folders within folders), improved metadata handling, and better scalability for the Macintosh platform. From a digital forensics perspective, this historical transition matters because examiners may encounter legacy Macintosh media or disk images where understanding the file system family helps interpret catalog structures, allocation behavior, and metadata artifacts.
The other options do not fit the "replace MFS" requirement.NTFSis Microsoft's Windows file system.APFS (Apple File System)is Apple's modern file system introduced much later (primarily for SSDs, with features like snapshots and strong encryption support) and it replaced HFS+ in newer macOS versions-not MFS.
Filesystem Hierarchy Standard (FHS)is a UNIX/Linux directory layout standard, not a Macintosh disk file system. Therefore, the Apple-developed file system that replaced MFS isHierarchical File System (HFS), which corresponds toOption D.

A forensic investigator is collecting volatile data such as system information and network information present in the registries, cache, DLLs, and RAM of digital devices through its normal interface.
Identify the data acquisition method the investigator is performing.
正解：A
解説：
The scenario describes the investigator collectingvolatileartifacts-specifically information inRAM, activeDLLs, system and network state, and transient data held incacheand similar runtime locations-through the device's normal interface while the system is running. In digital forensics documentation, this is the defining characteristic oflive acquisition(also called live response). Live acquisition is performed when the system remains powered on so that investigators can capture evidence that would be lost on shutdown, such as running processes, open network connections, logged-on sessions, loaded modules/DLLs, encryption keys, and portions of registry data that exist in memory or are actively changing.
By contrast,static acquisitionanddead acquisitionare conducted when the system is powered off (or the evidence drive is imaged outside the running OS), focusing primarily on persistent storage such as disk sectors and file system structures.Non-volatile data acquisitionrefers to collecting persistent data stored on media (e.g., files on disk), which does not match the emphasis on RAM and other volatile components in the question. Because the investigator is explicitly collecting volatile data from a running system via its normal interface, the correct method isLive acquisition (B).
質問 # 57
Which of the following types of phishing attacks allows an attacker to exploit instant messaging platforms by employing IM as a tool to spread spam?
正解：C
解説：
Spimmingis defined in digital forensics and cybercrime references asspam over instant messaging (IM). It is a social-engineering variant where attackers use instant messaging platforms (and sometimes chat apps) to deliver unsolicited bulk messages containing malicious links, fraudulent offers, credential-harvesting lures, or malware downloads. Because IM messages are often delivered in real time and can appear to come from known contacts (via compromised accounts), spimming can achieve higher click-through rates than traditional email spam. For investigators, spimming incidents commonly leave artifacts such as chat logs, message timestamps, sender identifiers, embedded URLs, and sometimes downloaded payload traces on the endpoint.
These artifacts help establish attacker infrastructure (domains, IPs), victim interaction (click events, file creation), and timeline correlation with network logs.
The other options do not match the "IM as a tool to spread spam" description.Whalingtargets high-profile individuals via highly tailored phishing, typically email-based.Pharmingredirects users to fraudulent websites (often via DNS or host-file manipulation) without relying on bulk IM spam.Spear phishingis targeted phishing toward specific individuals or groups, not necessarily IM spam. Therefore, the phishing/spam attack that exploits instant messaging platforms isSpimming (C).
質問 # 58
Sam, a digital forensic expert, is working on a case related to file tampering in a system at the administrative department of an organization. In this process, Sam started performing the following steps to analyze the acquired data to draw conclusions related to the case.
1.Analyze the file content for data usage.
2.Analyze the date and time of file creation and modification.
3.Find the users associated with file creation, access, and file modification.
4.Determine the physical storage location of the file.
5.Generate a timeline.
6.Identify the root cause of the incident.
Identify the type of analysis performed by Sam in the above scenario.
正解：D
解説：
The listed actions describe theexamination and interpretation of acquired evidence, which aligns withdata analysisin the digital forensics investigation process. After collection and acquisition, examiners analyze evidence by validating what the data contains (file content and usage), interpretingMAC times(creation
/modification and related timestamps), attributing actions tousers and accounts(who created, accessed, or modified the file), and determiningwhere the file resides physically/logicallyon storage (path, volume, clusters
/blocks, and whether it appears in allocated/unallocated areas). Generating atimelineis a core analytical task used to correlate file events with system activity and other artifacts to reconstruct sequence and intent. Finally,
"identify the root cause of the incident" represents the analytical conclusion derived from correlating artifacts and timeline events.
The other choices do not match the described work.Search and seizureis the legal/field activity of locating and securing evidence sources, not interpreting artifacts.Reportingis the documentation phase after analysis, where findings and methods are written up.Case analysisis broader and can include overall strategy and interpretation, but the question's focus is explicitly on analyzing acquired data and producing forensic conclusions, which isdata analysis.
