質問 # 51
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.
正解：A
解説：
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).
質問 # 52
In which of the following attacks does an attacker trick high-profile executives such as CEOs, CFOs, politicians, and celebrities to reveal critical corporate and personal information through email or website spoofing?
正解：D
解説：
The scenario describes a targeted social-engineering attack aimed specifically athigh-profile individuals (CEOs, CFOs, politicians, celebrities) and usesemail or website spoofingto deceive them into disclosing sensitive information. In digital forensics and incident response documentation, this is most accurately categorized aswhaling, a specialized form of phishing that focuses on "big targets" (often called "high-value targets" or "VIPs"). Whaling campaigns typically use highly tailored pretexts (e.g., legal subpoenas, board communications, invoice/payment requests, HR or executive directives) and may include spoofed sender domains, look-alike websites, or fraudulent login pages to harvest credentials and confidential corporate data.
Because executives often have access to financial systems, strategic documents, and privileged communications, attackers concentrate effort on realism and personalization, making whaling distinct from broad, generic phishing.
By contrast,smishingis phishing conducted via SMS/text messages,spimmingis spam over instant messaging platforms, andidentity fraudis a broader category involving impersonation/misuse of personal data but does not specifically denote the executive-targeted spoofing technique described. Therefore, the attack type in the question isWhaling (A).
質問 # 53
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?
正解：C
解説：
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.
質問 # 54
James, a forensic specialist, was appointed to investigate an incident in an organization. As part of the investigation, James is attempting to identify whether any external storage devices are connected to the internal systems. For this purpose, he employed a utility to capture the list of all devices connected to the local machine and removed suspicious devices.
Identify the tool employed by James in the above scenario.
正解：A
質問 # 55
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?
正解：B
解説：
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).
