NEW QUESTION # 11
Which of the following hives in the Windows Registry hierarchical database is volatile in nature and contains file-extension association information and programmatic identifier (ProgID), Class ID (CLSID), and Interface ID (IID) data?
- A. HKEY_CLASSES_ROOT
- B. HKEY_CURRENT_USER
- C. HKEY_CURRENT_CONFIG
- D. HKEY_LOCAL_MACHINE
Answer: A
Explanation:
HKEY_CLASSES_ROOT (HKCR)is the Windows Registry location that storesfile-association and COM registration data, including mappings forfile extensions(e.g.,.docx) toProgIDs, and COM object identifiers such asCLSIDand interface-related identifiers likeIID. In forensic examinations, HKCR is frequently consulted to determine which application is registered to open a specific file type, to identify COM objects that may enable persistence or abuse (e.g., through COM hijacking), and to correlate suspicious registry-based execution mechanisms with installed software.
HKCR is often described asvolatile in naturebecause it is not a single standalone hive file stored independently in the same way as SAM or SYSTEM; instead, it is amerged, runtime viewcreated by the OS primarily fromHKLM\Software\Classes(machine-wide registrations) andHKCU\Software\Classes(per-user overrides). This means what you see under HKCR can vary depending on the current user context and system state, and the effective associations/registrations may change when software is installed, updated, or when per- user settings override machine defaults.
The other options represent different scopes: HKLM is system configuration, HKCU is user profile configuration, and HKCC reflects the current hardware profile-not the primary COM/file association repository.
NEW QUESTION # 12
Williams, a forensic specialist, was tasked with performing a static malware analysis on a suspect system in an organization. For this purpose, Williams used an automated tool to perform a string search and saved all the identified strings in a text file. After analyzing the strings, he determined all the harmful actions that were performed by malware.
Identify the tool employed by Williams in the above scenario.
- A. Snagit
- B. ResourcesExtract
- C. Ezvid
- D. R-Drive Image
Answer: B
Explanation:
Instatic malware analysis, one of the quickest ways to infer capability is to extract and reviewstringsembedded in a binary. Strings frequently reveal command-and-control domains/IPs, mutex names, file paths, registry keys, user-agent values, suspicious commands (PowerShell/cmd), API names, error messages, encryption markers, and configuration fragments. Investigators often use automated utilities to extract these readable artifacts andexport them to a text filefor later triage, keyword searching, and correlation with other evidence (network logs, endpoint telemetry, and threat intel).
Among the provided options,ResourcesExtractbest matches this workflow. It is designed to extract embedded content from executable files-particularly Windows PE resources-and can export extracted textual items (including resource strings/strings tables and related embedded text) into external files for analysis. This aligns with "performed a string search and saved all the identified strings in a text file." The other choices do not fit:R-Drive Imageis a disk imaging/backup tool;Ezvidis for screen recording; andSnagitis for screenshots/screen capture. They do not perform automated extraction of strings from malware binaries as a static-analysis step. Therefore, the correct answer isResourcesExtract (B).
NEW QUESTION # 13
Steve, a professional hacker, attempted to hack Alice's banking account. To accomplish his goal, Steve used an automated tool to guess Alice's login credentials. The tool uses a trial-and-error method by attempting all possible combinations of usernames and passwords to determine the valid credentials.
Identify the type of attack initiated by Steve in the above scenario.
- A. Phishing attack
- B. Data manipulation attack
- C. Brute-force attack
- D. Trojan horse attack
Answer: C
Explanation:
The scenario describes an automated, trial-and-error attempt that triesall possible combinations of usernames and passwordsuntil a correct credential pair is found. This is the defining characteristic of abrute-force attack.
In digital forensics terminology, brute force is a direct password-guessing method that relies on exhaustive attempts (or systematically generated candidates) rather than tricking the user or exploiting a software flaw.
Investigators commonly recognize brute-force activity through artifacts such as repeated authentication failures in security logs, high-frequency login attempts from a single IP or distributed sources, account lockout events, and abnormal spikes in authentication traffic. In banking and web environments, it may also appear as repeated POST requests to login endpoints with varying credential pairs and consistent user-agent patterns, sometimes accompanied by throttling or CAPTCHA triggers.
The other options do not match the described "attempting all possible combinations" behavior.
Phishingobtains credentials by deception (fake emails/sites). ATrojan horsesteals data by running malicious code on the victim's system.Data manipulationfocuses on altering data integrity rather than credential guessing. Therefore, the correct attack type isBrute-force attack (A).
NEW QUESTION # 14
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?
- A. Spimming
- B. Spear phishing
- C. Pharming
- D. Whaling
Answer: A
Explanation:
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).
NEW QUESTION # 15
Which of the following layers of the TCP/IP model serves as the backbone for data flow between two devices in a network and enables peer entities on the source and destination devices to communicate with each other?
- A. Application layer
- B. Internet layer
- C. Network access layer
- D. Transport layer
Answer: D
Explanation:
In the TCP/IP model, theTransport layeris responsible forend-to-end communication between peer entitieson the source and destination systems. "Peer entities" here refers to the corresponding transport components (and the applications that use them) on two different hosts communicating across a network. This layer forms the practical "backbone" of host-to-host data flow because it provides the mechanisms that allow data to be deliveredfrom one endpoint process to another endpoint processreliably or efficiently, depending on the protocol used.
The Transport layer includes protocols such asTCPandUDP. TCP supports connection-oriented communication with sequencing, acknowledgments, retransmissions, and flow control-features that are fundamental when reconstructing sessions during network forensic investigations (e.g., rebuilding a file transfer or a web session). UDP provides connectionless delivery used by many services where speed is preferred over guaranteed delivery, which is also significant in investigations of DNS, streaming, or certain malware communications.
By contrast, theInternet layerfocuses on logical addressing and routing (IP), theNetwork access layerhandles local delivery on the physical/link network, and theApplication layerprovides user-facing protocols.
Therefore, the layer enabling peer communication between endpoints is theTransport layer (C).
NEW QUESTION # 16
Michael, a forensic expert, was assigned to investigate an incident that involved unauthorized intrusion attempts. In this process, Michael identified all the open ports on a system and disabled them because these open ports can allow attackers to install malicious services and compromise the security of the system or network.
Which of the following commands assisted Michael in identifying open ports in the above scenario?
- A. netstat -i
- B. ifconfig <interface> -promisc
- C. nmap -sT localhost
- D. netstat -rn
Answer: C
Explanation:
To identifyopen ports, investigators need a method that actively checks which TCP/UDP ports on a host are accepting connections. The commandnmap -sT localhostperforms aTCP Connect scanagainst the local system. In a connect scan, Nmap uses the operating system's normal networking API to attempt a full TCP three-way handshake to each targeted port. If the handshake completes, the port is reported asopen; if it is refused, it isclosed; and if filtered by firewall rules, it may appearfiltered. This directly supports Michael's objective of enumerating open ports so they can be reviewed and disabled to reduce the attack surface and prevent malicious services from being installed.
The other options do not enumerate open ports in the same way.netstat -ishows interface-level statistics (packets, errors) rather than listing listening services.netstat -rndisplays the routing table (routes and gateways), which helps understand network paths but not which ports are open.ifconfig <interface> -promisc relates to enabling/disabling promiscuous mode on an interface for packet capture, not port discovery.
Therefore, the command that assisted in identifying open ports isnmap -sT localhost (C).
NEW QUESTION # 17
A system that a cybercriminal was suspected to have used for performing an anti-social activity through the Tor browser. James reviewed the active network connections established using specific ports via Tor.
Which of the following port numbers does Tor use for establishing a connection via Tor nodes?
- A. 3024/4092
- B. 1026/64666
- C. 9150/9151
- D. 31/456
Answer: C
Explanation:
In Tor Browser deployments, Tor typically runs a local client ("tor" process) that exposes aSOCKS proxyfor applications (the browser) to send traffic into the Tor network and, optionally, acontrol interfacefor managing circuits and obtaining runtime status. In many forensic lab guides and Tor Browser bundle configurations, the default local SOCKS listening port is9150, and the associated Tor control port is commonly9151. This pairing is frequently referenced in investigations because endpoint triage (e.g., netstat outputs, firewall logs, EDR socket telemetry) may show local loopback connections from the browser to127.0.0.1:9150(SOCKS) and management communications involving9151(control).
From a network-forensics viewpoint, these ports help distinguish Tor Browser activity from other proxy tools:
the browser does not directly connect to Tor relays; instead, it hands traffic to the local SOCKS proxy, which then establishes encrypted circuits to Tor nodes. While Tor can be configured to use different ports, the question asks about the specific ports used for establishing Tor connections in typical Tor Browser setups, which aligns with9150/9151. Therefore, the correct option isD.
NEW QUESTION # 18
Which of the following techniques is used to compute the hash value for a given binary code to uniquely identify malware or periodically verify changes made to the binary code during analysis?
- A. Malware disassembly
- B. Strings search
- C. Local and online malware scanning
- D. File fingerprinting
Answer: D
Explanation:
File fingerprintingis the forensic technique of generating acryptographic hash(such as MD5, SHA-1, SHA-
256) for a file to create aunique, repeatable identifierfor that exact byte sequence. In malware forensics, analysts compute hashes to (1)uniquely identifya suspicious binary across cases and tools, (2) confirm whether two samples are identical or different variants, and (3)verify integrity over time-for example, ensuring the sample did not change during copying, extraction, sandbox handling, or during an analysis workflow that might inadvertently modify the file (e.g., patching, unpacking outputs, or tool-side normalization). Re-hashing at different stages provides a defensible way to demonstrate that the analyzed artifact is the same as the acquired artifact, supporting evidentiary integrity and chain-of-custody principles commonly emphasized in digital forensics documentation.
The other techniques do not primarily serve this purpose.Strings searchextracts readable text fragments but does not produce a unique integrity identifier.Local and online malware scanninguses signatures/reputation and may identify families, but it is not an integrity verification mechanism for the exact file bytes.Malware disassemblyhelps understand logic and instructions, not compute an identity hash. Therefore, the correct answer isFile fingerprinting (A).
NEW QUESTION # 19
Cooper, a forensic analyst, was examining a RAM dump extracted from a Linux system. In this process, he employed an automated tool, Volatility Framework, to identify any malicious code hidden inside the memory.
Which of the following plugins of the Volatility Framework helps Cooper detect hidden or injected files in the memory?
- A. ip addr show
- B. linux_malfind
- C. linux_netstat
- D. nmap -sU localhost
Answer: B
Explanation:
In memory forensics, "hidden or injected" malicious code typically refers toprocess injection,code caves, unbacked executable mappings, or regions of memory that aremarked executablebut do not align with normal, file-backed program segments. The Volatility Framework provides specialized plugins to locate these suspicious patterns.linux_malfindis the plugin designed to detectpotentially injected codeby scanning a process's memory mappings for characteristics that commonly indicate malicious presence-such asexecutable anonymous mappings, unusual permissions (e.g., RWX), and memory regions that contain shellcode-like byte patterns. This is highly relevant when malware attempts to avoid disk artifacts by living in memory or by injecting payloads into legitimate processes.
By contrast,linux_netstatis used to enumerate network connections and sockets from memory (useful for C2 analysis), but it does not focus on injected code regions.ip addr showandnmap -sU localhostare live-system networking commands, not Volatility plugins, and they are not suitable for analyzing a captured RAM image.
Therefore, to detect hidden/injected malicious code in a Linux RAM dump using Volatility, the correct plugin islinux_malfind (A).
NEW QUESTION # 20
An investigator wants to extract information about the status of the network interface cards (NICs) in an organization's Windows-based systems. Identify the command-line utility that can help the investigator detect the network status.
- A. PsList
- B. ipconfig
- C. ifconfig
- D. PsLoggedOn
Answer: B
Explanation:
On Windows systems,ipconfigis the standard command-line utility used to display and troubleshootTCP/IP configurationand the operational status of network interfaces. From a forensic and incident-response perspective, it helps investigators quickly identify whether a NIC is enabled and configured, and it reveals key network parameters tied to "network status," such as theassigned IPv4/IPv6 addresses,subnet mask,default gateway, andDNS servers. Using variants likeipconfig /all, responders can also capture adapter-specific metadata includingMAC address (physical address), DHCP enablement, DHCP server, lease timestamps, and interface descriptions-useful for correlating an endpoint to switch-port logs, DHCP logs, and network monitoring data. This is often part of live triage because it documents the system's current connectivity and routing context at the time of seizure or investigation.
The other options are not appropriate for NIC status:PsLoggedOnreports logged-on users, andPsListenumerates running processes-both are Sysinternals tools focused on user/process state rather than network interface configuration.ifconfigis a UNIX/Linux command (and not the primary Windows utility), so it would not be the correct choice for Windows-based systems. Therefore,ipconfig (A)is correct.
NEW QUESTION # 21
Bob, a network specialist in an organization, is attempting to identify malicious activities in the network. In this process, Bob analyzed specific data that provided him a summary of a conversation between two network devices, including a source IP and source port, a destination IP and destination port, the duration of the conversation, and the information shared during the conversation.
Which of the following types of network-based evidence was collected by Bob in the above scenario?
- A. Session data
- B. Statistical data
- C. Alert data
- D. Full content data
Answer: A
Explanation:
The description matchessession data, often calledflow records(for example, NetFlow/IPFIX-style evidence).
In network forensics, session/flow evidence summarizes a communication "conversation" between two endpoints using the5-tuple(source IP, source port, destination IP, destination port, and protocol) and typically addsstart/end time or duration,bytes/packets sent, and sometimes directionality. This allows an investigator to reconstructwho talked to whom, when, and for how long, even when packet payloads are unavailable (because of encryption, storage limits, or privacy constraints).
"Full content data" refers to complete packet captures (PCAP) containing payload bytes; that is far more detailed and would include the actual transmitted content, not just a summary. "Statistical data" is broader aggregate metrics (overall bandwidth trends, interface counters) and generally lacks per-conversation attribution. "Alert data" comes from IDS/IPS/SIEM detections and represents triggered events or signatures, not a neutral conversation summary.
Because Bob's evidence contains per-connection identifiers (IPs/ports) and conversation duration-typical of flow/session summaries-the correct evidence type isSession data (C).
NEW QUESTION # 22
Identify the investigation team member who is responsible for evidence gathered at the crime scene and maintains a record of the evidence, making it admissible in a court of law.
- A. Incident responder
- B. Incident analyzer
- C. Evidence examiner
- D. Evidence manager
Answer: D
Explanation:
The role described-being responsible for evidence gathered at the crime scene and maintaining a record that makes the evidence admissible in court-matches the duties of anEvidence manager. In digital forensics practice, admissibility depends heavily on provingintegrity, authenticity, and continuity of possession. The evidence manager ensures these requirements by implementing and documenting thechain of custody, which is the formal, chronological record of who collected the evidence, when and where it was collected, how it was packaged and labeled, how it was transported, where it was stored, and every time it was accessed or transferred. This role also enforces evidence handling procedures such as tamper-evident sealing, secure storage controls, access logging, and verification steps (for example, ensuring hashes are recorded and preserved for forensic images).
Anincident responderfocuses on containment and immediate actions during an incident; anincident analyzerperforms technical analysis and correlation of artifacts; and anevidence examinerconducts detailed forensic examinations on acquired data. While these roles interact with evidence, the specific responsibility for maintaining custody documentation and evidence records to support legal admissibility belongs to theEvidence manager, makingDthe correct answer.
NEW QUESTION # 23
Which of the following Tor relay nodes in the Tor circuit is designed to transfer data in an encrypted format?
- A. Guard relay
- B. Entry relay
- C. Middle relay
- D. Exit relay
Answer: C
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 # 24
Which of the following tools helps a forensics investigator develop and test across multiple operating systems in a virtual machine for Mac and allows access to Microsoft Office for Windows?
- A. Riverbed Modeler
- B. Parallels Desktop 16
- C. NetSim
- D. Camtasia
Answer: B
Explanation:
A common requirement in macOS-focused forensic labs is the ability to runmultiple operating systemson a single Mac for controlled testing, malware detonation in a sandbox, reproduction of user activity, and validation of artifacts across platforms. This is typically achieved throughdesktop virtualization, where a hypervisor hosts guest operating systems (such as Windows and various Linux distributions) inside virtual machines.Parallels Desktop 16is a Mac virtualization solution built specifically to run Windows on macOS with strong integration features (such as shared clipboard, folder sharing, and "coherence" modes that allow Windows applications to appear alongside Mac applications). This capability aligns with the question's description: developing and testing across multiple OSs in VMs on a Mac and enabling use ofMicrosoft Office for Windowswithin that Windows guest environment.
The other tools do not fit.Riverbed ModelerandNetSimare primarilynetwork modeling/simulationtools used for network design and training, not desktop virtualization.Camtasiais used forscreen recording and video editing, which can support documentation but does not provide a VM environment. Therefore, the only option that directly provides cross-OS virtual machines on macOS and supports running Windows applications like Microsoft Office isParallels Desktop 16 (B).
NEW QUESTION # 25
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)?
- A. Apple File System
- B. New Technology File System
- C. Hierarchical File System
- D. Filesystem Hierarchy Standard
Answer: C
Explanation:
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.
NEW QUESTION # 26
Given below are different steps involved in event correlation.
Event masking
Event aggregation
Root cause analysis
Event filtering
Identify the correct sequence of steps involved in event correlation.
- A. 2-->1-->4-->3
- B. 1-->3-->2-->4
- C. 2-->4-->3-->1
- D. 1-->3-->4-->2
Answer: A
Explanation:
In event correlation (as applied in SOC/SIEM-driven investigations), the workflow typically starts byreducing complexityandnormalizing what "one incident" looks likebefore attempting conclusions about causality.Event aggregation (2)is performed early to combine multiple low-level, related events (for example repeated authentication failures, repeated firewall denies, or multiple IDS hits for the same signature) into higher-level
"grouped" records. This prevents analysts from treating every raw log line as a separate incident and makes correlation computationally and operationally feasible.
Next,event masking (1)suppresses events that are already known to be irrelevant or repetitive in a way that does not add investigative value (for example, routine scheduled scans, approved admin tools, or duplicate alerts already represented in the aggregated set). After masking,event filtering (4)further removes remaining noise using rules, thresholds, whitelists, time windows, or relevance criteria (scope, asset criticality, and known-benign sources), leaving a cleaner dataset that represents probable security-relevant activity.
Only after the dataset is consolidated and noise-reduced doesroot cause analysis (3)become reliable, because RCA depends on a clear chain of correlated events to identify the initiating action and propagation path.
Hence the correct sequence is2 # 1 # 4 # 3 (Option B).
NEW QUESTION # 27
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?
- A. Cain & Abel
- B. R-Studio
- C. Ophcrack
- D. Rohos Mini Drive
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.
NEW QUESTION # 28
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?
- A. Web artifacts
- B. Data carving
- C. Timeline analysis
- D. Multimedia
Answer: B
Explanation:
When a file is deleted on common file systems, the operating system typically removes the directory reference and marks the previously used clusters/blocks asunallocated, but the underlying file content may remain on disk until it is overwritten. Digital forensics procedures emphasize that recovering such deleted content often requires examining unallocated space rather than relying only on file system metadata.Autopsy's "Data Carving"function is specifically intended for this purpose: it scans unallocated space (and sometimes slack space) forfile signatures(headers/footers and internal structure patterns) and reconstructs recoverable files even when the original filename, path, or metadata is missing.
This directly matches the scenario: Jack recovered deleted files fromunallocated space, which is the classic use case for carving. The other options in Autopsy support different investigative goals.Timeline analysiscorrelates timestamps from multiple artifacts to reconstruct sequences of activity, but it does not itself reconstruct deleted file content from raw disk areas.Web artifactsfocuses on browser history, downloads, cookies, and related traces.Multimediahelps categorize and analyze media files (e.g., images/videos), but it is not the primary mechanism for recovering deleted data from unallocated space. Therefore, the Autopsy function that enabled the recovery described isData carving (D)
NEW QUESTION # 29
Kelly, a professional hacker, used her laptop to perform illegal cyber activities for monetary gain on many victims. She securely locked her laptop using BitLocker software. Using this tool, she locked an entire volume using a secret key to deny access to the system.
Identify the anti-forensic technique used by Don in the above scenario.
- A. File carving
- B. Trail obfuscation
- C. Encryption
- D. Artifact wiping
Answer: C
Explanation:
The scenario describes the use ofBitLockerto lock an entire disk volume with asecret key, preventing access to the contents. In digital forensics, this is a classic example ofencryption as an anti-forensics technique. Full- disk or full-volume encryption transforms readable data into ciphertext using cryptographic algorithms so that, without the correct key (password, recovery key, TPM-bound protector, etc.), the data is computationally infeasible to interpret. This directly obstructs evidence acquisition and analysis because a forensic image of the drive will largely contain encrypted blocks rather than interpretable file system structures and user data.
This differs from the other options:file carvingis a forensic recovery method (often used by investigators) that reconstructs files from unallocated space; it is not an anti-forensics method used to block access.Artifact wipingattempts to erase traces by deleting or overwriting files, logs, or free space, but it does not inherently prevent access to remaining data if wiping is incomplete.Trail obfuscationinvolves misleading or altering logs and traces to confuse investigators, whereas encryption primarilydenies content visibilityby design. Because BitLocker is explicitly a volume encryption mechanism used here to deny access, the correct anti-forensic technique isEncryption (D).
NEW QUESTION # 30
John, a forensic officer, was working on a criminal case. He employed imaging software to create a copy of data from the suspect device on a storage medium for further investigation. For developing an image of the original data, John used a software application that does not allow an unauthorized user to alter the image content on storage media, thereby retaining an unaltered image copy.
Identify the data acquisition step performed by John in the above scenario.
- A. Planned for contingency
- B. Enabled write protection on the evidence media
- C. Sanitized the target media
- D. Validated data acquisition
Answer: B
Explanation:
The scenario emphasizes that John used an application (or mechanism) thatprevents alteration of the acquired image content, ensuring the image remainsunalteredand protected from unauthorized modification. In forensic acquisition standards, this corresponds toenabling write protectionduring imaging-commonly implemented using awrite blocker(hardware or controlled software write-protection) to prevent any writes to the source evidence and, where applicable, to protect the integrity of the evidence copy from accidental or unauthorized changes. The purpose is to preserve evidential integrity by ensuring that neither the original media nor the forensic image is modified during handling, analysis preparation, or transfer.
"Validated data acquisition" refers to confirming the image is an exact duplicate, typically by computing and comparing cryptographic hashes (e.g., MD5/SHA) of the source and the acquired image. While validation is essential, the question specifically highlightspreventing alteration, not verifying equality. "Sanitized the target media" is the step of wiping/clearing the destination drive before acquisition to avoid contamination, which is not what is described. "Planned for contingency" relates to operational planning for unexpected issues (equipment failure, encryption, power loss), not integrity protection. Therefore, the best match isEnabled write protection on the evidence media (A).
NEW QUESTION # 31
Below is an extracted Apache error log entry.
"[Wed Aug 28 13:35:38.878945 2020] [core:error] [pid 12356:tid 8689896234] [client 10.0.0.8] File not found: /images/folder/pic.jpg" Identify the element in the Apache error log entry above that represents the IP address from which the request was made.
- A. 10.0.0.8
- B. 13:35:38.878945
- C. 0
- D. 1
Answer: A
Explanation:
Apache error logs record key metadata about server-side events in a structured format that is widely used in web attack investigations. In the provided entry, each bracketed field represents a specific attribute: the first bracket contains the timestamp, the next contains the module and severity (e.g.,core:error), then the process
/thread identifiers (pidandtid), followed by the client identifier. The client field is explicitly labeled[client ...], and it captures thesource IP address(or sometimes hostname) that initiated the HTTP request which resulted in the logged error.
Here,[client 10.0.0.8]indicates that the request originated from IP address10.0.0.8. This is the critical element investigators use to attribute suspicious activity (such as probing for missing files, scanning directories, or exploitation attempts) to a specific network source. The other values are not the client IP:13:35:38.878945is the time component of the timestamp,12356is the Apache process ID, and8689896234is the thread ID handling the request. Therefore, the IP address from which the request was made is10.0.0.8 (C).
NEW QUESTION # 32
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.
- A. Dead acquisition
- B. Live acquisition
- C. Non-volatile data acquisition
- D. Static acquisition
Answer: B
Explanation:
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).
NEW QUESTION # 33
Jennifer, a forensics investigation team member, was inspecting a compromised system. After gathering all the evidence related to the compromised system, she disconnected the system from the network to stop the spread of the incident to other systems.
Identify the role played by Jennifer in the forensics investigation.
- A. Expert witness
- B. Incident analyzer
- C. Evidence manager
- D. Incident responder
Answer: D
Explanation:
Jennifer's actions match the responsibilities of anincident responder, whose job spans immediatecontainment, preservation, and stabilizationactivities during an active or recently active security incident. In standard digital forensics and incident response (DFIR) procedures, responders first take steps topreserve evidence(e.g., documenting the scene, capturing volatile data when appropriate, and collecting relevant system artifacts) and then executecontainment measuresto prevent further harm. Disconnecting a compromised host from the network is a classic containment control used to stop malware propagation, block command-and-control communications, and prevent lateral movement to other systems.
Anincident analyzertypically focuses on deeper technical analysis-timeline reconstruction, root cause determination, and correlating artifacts across hosts and logs-rather than performing immediate containment.
Anevidence manageris primarily responsible for maintaining evidence integrity, chain of custody, storage, labeling, and access control, not operational containment. Anexpert witnessprovides formal testimony and interpretation in legal or disciplinary proceedings and is not usually involved in live containment actions.
Since Jennifer bothgathered evidenceand thenisolated the system to stop spread, the role most consistent with documented DFIR responsibilities isIncident responder (A).
NEW QUESTION # 34
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?
- A. Logical acquisition
- B. Bit-stream disk-to-disk
- C. Bit-stream disk-to-image-file
- D. Sparse acquisition
Answer: B
Explanation:
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).
NEW QUESTION # 35
Bob, a security specialist at an organization, extracted the following IIS log from a Windows-based server:
"2019-12-12
06:11:41 192.168.0.10 GET /images/content/bg_body1.jpg - 80 - 192.168.0.27 Mozilla/5.0+(Windows+NT+6.
3;+WOW64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/48.0.2564.103+Safari/537.36
http://www.moviescope.com/css/style.css 200 0 0 365"
Identify the element in the above IIS log entry that indicates the request was fulfilled without error.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
In Microsoft IIS (W3C Extended) logging, each request line records multiple standardized fields that help investigators reconstruct what was accessed, by whom, and with what outcome. Among these fields, the most direct indicator of whether the server successfully handled the request is theHTTP status codecaptured in thesc-statusfield. A status code of200means"OK", indicating the server located the requested resource (here,
/images/content/bg_body1.jpg) and returned it successfully to the client without application-level failure.
Other numbers in the entry represent different attributes:80is the server port used for the HTTP request,
192values appear as part of IP addressing (client/server addresses), and537is embedded in the user-agent string (AppleWebKit build number), not a success indicator. IIS often logs additional substatus and Win32 status values (e.g.,sc-substatusandsc-win32-status) to refine the outcome; in the shown line, those follow the
200 as "200 0 0 ...", reinforcing that no substatus error or OS-level error occurred. Therefore,200is the element confirming the request was fulfilled without error.
