NEW QUESTION # 76
Clark, a digital forensic expert, was assigned to investigate a malicious activity performed on an organization' s network. The organization provided Clark with all the information related to the incident. In this process, he assessed the impact of the incident on the organization, reasons for and source of the incident, steps required to tackle the incident, investigation team required to handle the case, investigative procedures, and possible outcome of the forensic process.
Identify the type of analysis performed by Clark in the above scenario.
Answer: A
Explanation:
The activities described align withcase analysis, which is the structured, high-level evaluation performed at the beginning (and throughout) a digital forensic investigation to define scope, strategy, resources, and expected deliverables. Case analysis focuses on understanding theoverall incident context: how the organization is affected (business/operational impact), what is believed to have happened (incident reasons and likely source), and what must be done to control and investigate it (containment steps and investigative approach). It also includes planning elements such as identifying theinvestigation team composition(roles, skills, authority), definingproceduresto be followed (evidence handling, chain of custody, acquisition priorities, legal/HR requirements), and anticipating thepossible outcomes(reports, remediation actions, disciplinary/legal actions, or prosecution support).
By contrast,traffic analysisis narrowly focused on examining network packets/flows to infer communications and attacker behavior;log analysiscenters on parsing and correlating event records (firewall, server, endpoint logs); anddata analysistypically refers to examining acquired artifacts (files, memory images, timelines) for evidentiary content. Because Clark is assessing impact, cause/source, response steps, staffing, procedures, and outcomes-an overall investigative planning and evaluation function-the correct choice isCase analysis (B).
NEW QUESTION # 77
Which of the following Tor relay nodes in the Tor circuit is designed to transfer data in an encrypted format?
Answer: B
Explanation:
In a standard Tor circuit, a client typically builds a three-hop path:Entry/Guard # Middle # Exit. Tor uses onion routing, where the client wraps the payload in multiple encryption layers-one for each hop. Each relay removes (decrypts) only its own layer to learn thenext hop, but not the complete route or the original payload in the clear. Themiddle relayis specifically positioned toforward traffic between the entry/guard and the exit while it remains onion-encrypted end-to-end within the Tor network. Because it neither connects to the user's local network (like the entry/guard) nor to the public destination (like the exit), its primary role isencrypted transit/forwarding, helping break the linkage between source and destination. By contrast, theexit relayis where traffic leaves Tor; unless the application layer uses TLS/HTTPS, the exit may deliver data to the destination inunencryptedform on the open Internet. Theentry/guardprotects against certain traffic-correlation risks by being stable, but it is not uniquely "the" encrypted-transfer node. Therefore, the best single answer isMiddle relay (D).
NEW QUESTION # 78
Bob, a forensic investigator, is investigating a live Windows system found at a crime scene. In this process, Bob extracted subkeys containing information such as SAM, Security, and software using an automated tool called FTK Imager.
Which of the following Windows Registry hives' subkeys provide the above information to Bob?
Answer: D
Explanation:
In Windows forensics, the Registry is organized into logical root keys ("hives") that aggregate configuration and security data. The items named in the question-SAM,SECURITY, andSOFTWARE-aresystem-wide registry hivesstored on disk (typically under the system's configuration directory) and loaded at runtime underHKEY_LOCAL_MACHINE (HKLM). Investigators rely on these hives because they contain high- value evidence: theSAMhive stores local account database information (including user and group identifiers and credential-related material), theSECURITYhive holds system security policy and LSA-related settings, and theSOFTWAREhive contains installed software, application configuration, and many operating system settings relevant for program execution and persistence analysis.
Tools likeFTK Imagercan extract these hives (or their live-memory representations) during triage to preserve volatile context and enable offline parsing while maintaining evidentiary integrity. The other root keys do not match these specific hives:HKEY_CURRENT_USERis per-user profile data, HKEY_CURRENT_CONFIGreflects current hardware profile, andHKEY_CLASSES_ROOTis primarily file association/COM class mapping (largely derived from HKLM\Software\Classes and HKCU\Software\Classes). Therefore, the correct hive root that provides SAM, SECURITY, and SOFTWARE subkeys isHKEY_LOCAL_MACHINE (B).
NEW QUESTION # 79
Identify the malware analysis technique in which the investigators must take a snapshot of the baseline state of the forensic workstation before malware execution.
Answer: A
Explanation:
The technique described-taking a snapshot of the baseline state of the forensic workstation before executing malware-aligns withMonitoring host integrity. In malware forensics, investigators often perform controlled execution (dynamic analysis) and need a reliable way to identifywhat changed on the systemas a direct result of the malware run. Host integrity monitoring is a structured approach where the examiner first captures aknown-good baselineof critical system elements such as file system state (key directories, system binaries), registry/configuration state, running services, installed drivers, scheduled tasks, and sometimes hash inventories of important files. After malware execution, the investigator captures a second snapshot and performsdifferential comparisonto determine newly created/modified files, persistence mechanisms, configuration changes, dropped payloads, and tampering attempts.
This baseline-before/after comparison is fundamental for attributing changes to the sample, supporting repeatability, and documenting evidence in a defensible manner. The other options do not require a workstation baseline snapshot in this sense:online malware scanningchecks a file against signatures/reputation services;string searchextracts readable strings from binaries; andfile fingerprintingtypically refers to hashing to uniquely identify a file, not system-wide state comparison. Therefore, the correct answer isMonitoring host integrity (B).
NEW QUESTION # 80
Kelvin, a forensic investigator at FinCorp Ltd., was investigating a cybercrime against the company. As part of the investigation process, he needs to recover corrupted and deleted files from a Windows system. Kelvin decided to use an automated tool to recover the damaged, corrupted, or deleted files.
Which of the following forensic tools can help Kelvin in recovering deleted files?
Answer: B
Explanation:
In Windows forensics, recovering deleted or corrupted files typically requires afile-system aware data recovery toolthat can interpret NTFS/FAT metadata and scan disk structures for lost file records and residual content.R-Studiois designed specifically for data recovery: it can locate and rebuild deleted files by analyzing file system metadata (such as NTFS MFT entries and directory records), recover data from formatted or damaged partitions, and perform raw "signature-based" scans to carve files when metadata is missing. This aligns directly with Kelvin's need for an automated method to restoredamaged, corrupted, or deletedfiles from a Windows system.
The other options do not match the stated recovery objective.OphcrackandCain & Abelare password recovery
/auditing tools used to obtain credentials (e.g., cracking hashes), not to restore deleted files.Rohos Mini Driveis primarily an encryption/secure storage utility for creating encrypted containers, which may protect data but does not function as a forensic recovery tool for deleted or corrupted files. Therefore, among the listed tools,R-Studio (C)is the correct choice for automated recovery of deleted files in a Windows forensic investigation.
