問題 #64
In which of the following malware distribution techniques does the attacker use tactics such as keyword stuffing, doorway pages, page swapping, and adding unrelated keywords to improve the search-engine ranking of their malware pages?

答案：A

解題說明：
The technique described-keyword stuffing, doorway pages, page swapping, and inserting unrelated high- traffic keywords-matchesblack-hat search-engine optimization (SEO), often calledSEO poisoningin digital forensics and threat intelligence materials. In this distribution method, attackers manipulate search engine ranking algorithms so that malicious or malware-hosting pages appear near the top of search results for popular queries (breaking news, software downloads, trending events, adult content, etc.). Doorway pages are created to rank well for specific terms and then funnel victims to malicious landing pages. Page swapping (or
"bait-and-switch") occurs when a page is optimized and indexed as benign content, but later replaced or dynamically served as malicious content once it has gained ranking and trust signals. Keyword stuffing and unrelated keyword injection further exploit ranking heuristics by artificially increasing perceived relevance.
From a forensic perspective, black-hat SEO campaigns often leave artifacts such as compromised websites with injected spam links, abnormal redirect chains, cloaking behavior (different content for crawlers vs.
users), and malicious scripts or exploit kit references. The other options do not primarily rely on search ranking manipulation: drive-by downloads are about silent exploitation on visit, spearphishing relies on targeted messaging, and clickjacking tricks users into unintended clicks. Hence,Black-hat search-engine optimization (C)is correct.


問題 #65
Which of the following layers of the TCP/IP model includes protocols such as Frame Relay, SMDS, Fast Ethernet, SLIP, PPP, FDDI, ATM, Ethernet, and ARP to enable a machine to deliver the desired data to other hosts in the same network?

答案：D

解題說明：
The protocols listed-Frame Relay, SMDS, Fast Ethernet, SLIP, PPP, FDDI, ATM, Ethernet, and ARP- belong to the portion of the TCP/IP model responsible forlocal network deliveryand direct interaction with the physical media and link-layer addressing. In TCP/IP terminology, this is theNetwork Access layer(also called the Link layer or Network Interface layer). It combines functions that map closely to the OSIData LinkandPhysicallayers.
This layer is essential for delivering frames within the same network segment because it governs how devices access the medium (e.g., Ethernet), how frames are formatted and transmitted, and how hardware addressing works.ARP (Address Resolution Protocol)is especially important here: it resolvesIP addresses to MAC addressesso that an IP packet can be encapsulated into a link-layer frame and delivered to the correct local host or next-hop gateway. Technologies like PPP/SLIP support point-to-point links, while Frame Relay/ATM represent WAN/link technologies, all of which still sit under IP and provide the mechanisms for moving data across the immediate network path.
TheInternet layerhandles IP routing between networks, theTransport layerprovides end-to-end host communications (TCP/UDP), and theApplication layerprovides user protocols. Therefore, the correct layer isNetwork access layer (A).


問題 #66
Clark, a security professional, identified that one of the systems in the organization is infected with malware and was used for creating a backdoor. Clark employed an automated tool to analyze the system's memory and detect malicious activities performed on the system.
In the above scenario, which of the following tools did Clark employ to detect malicious activities performed on the system?

答案：B

解題說明：
The question specifies anautomated tool to analyze the system's memoryand detect malicious activity associated with amalware backdoor. In malware forensics and incident response practice, memory analysis is used to identify artifacts that may not be reliably visible on disk, such as injected code, hidden processes, suspicious DLLs/modules, live network connections, persistence objects loaded in memory, and indicators of compromise tied to backdoors.Redline(commonly referenced in DFIR training) is purpose-built forhost investigation and memory analysis. It can collect and analyze volatile data, including running processes, loaded modules, handles, drivers, network sessions, and other runtime indicators that help investigators spot malicious behavior and attribute it to specific executables or injected components.
The other options do not align with memory forensics.Medusais primarily a credential brute-force/login auditing tool, not a memory analysis utility.Shodanis an Internet-wide device search engine used for external reconnaissance, not for local host RAM inspection.Wiresharkis a packet capture and protocol analysis tool focused on network traffic, not automated memory artifact collection and analysis. Therefore, the tool Clark used to analyze memory and detect malicious activity isRedline (B).


問題 #67
Bob, a professional hacker, targeted an organization to launch attacks. Bob gathered information such as network topology and a list of live hosts. Based on the collected information, he launched further attacks over the organization's network.
Identify the type of network attack Bob initiated on the target organization in the above scenario.

答案：A

解題說明：
The activity described-collectingnetwork topologydetails and compiling alist of live hosts-matches the reconnaissance phase commonly referred to asenumeration. In digital forensics and incident response documentation, enumeration is the systematic process of discovering and extracting information about a target environment to support later exploitation. It typically follows (or overlaps with) scanning and includes identifying active IP addresses, reachable systems, open ports/services, device roles, OS fingerprints, domain information, shared resources, user/group details, and routing or segmentation clues that reveal how the network is structured.
This information is then used to plan "further attacks," such as targeting exposed services, choosing exploit paths, locating high-value systems, and selecting lateral movement routes. From a forensic standpoint, enumeration attempts often leave traces in firewall logs, IDS alerts, and endpoint artifacts (e.g., bursts of connection attempts across many hosts/ports, ICMP echo sweeps, ARP discovery on local segments, and repeated DNS queries).
The other options do not fit:data modificationinvolves altering data integrity;session hijackingtargets active sessions/tokens; andbuffer overflowis an exploitation technique against vulnerable software, not the information-gathering step described. Therefore, the correct answer isEnumeration (B)


問題 #68
Jack, a forensic investigator, was appointed by an organization to perform a security audit on a Linux system.
In this process, Jack collected information about the present status of the system and listed all the applications running on various ports to detect malicious programs.
Which of the following commands can help Jack determine any programs/processes associated with open ports?

答案：C

解題說明：
On Linux, a key step in a forensic triage or security audit is mappingopen/listening portsto theowning processso investigators can identify suspicious services (backdoors, unauthorized daemons, rogue remote- access tools) and correlate them with binaries, users, startup mechanisms, and timestamps. The command netstat -tulpnis designed for exactly this purpose. In this switch set:-tlimits output to TCP sockets,-uincludes UDP sockets,-lshows only listening sockets (open ports awaiting connections),-pdisplays the owningprocess name and PID, and-nprevents name resolution by showing numeric IP addresses and ports (faster and avoids altering evidence via DNS queries). This combination yields a concise list of active listening ports and the processes bound to them, which is highly valuable for detecting unexpected services and attributing network exposure to a specific executable.
The other options do not provide process-to-port attribution:netstat -ishows interface statistics,ip rshows the routing table, andnetstat -rndisplays the routing table in numeric form. Therefore, the correct command is netstat -tulpn(D).
