質問 # 37
Bob, a forensic investigator, was instructed to review a Windows machine and identify any anonymous activities performed using it. In this process, Bob used the command "netstat -ano" to view all the active connections in the system and determined that the connections established by the Tor browser were closed.
Which of the following states of the connections established by Tor indicates that the Tor browser is closed?
正解：C
解説：
In Windows network forensics,netstat -anois commonly used to correlateTCP connection stateswithprocess identifiers (PIDs)to understand which application created or used a connection. When Tor Browser is actively communicating, outbound circuits typically appear asESTABLISHEDconnections to Tor relays (entry/guard nodes) or local loopback endpoints used by Tor components. After the browser is closed and the application tears down connections, Windows TCP/IP behavior often leaves recently closed sockets inTIME_WAIT.
TIME_WAITis a normal TCP state that appears after a connection has been actively closed. It exists to ensure delayed packets from the old session are not misinterpreted as belonging to a new session and to allow proper retransmission of the final ACK if needed. From an investigative standpoint, seeing Tor-related endpoints transition from ESTABLISHED toTIME_WAITstrongly indicates the sessions were terminated and the application is no longer maintaining live network traffic.
By contrast,CLOSE_WAITusually means the remote side has closed but the local application has not fully closed its socket yet,LISTENINGindicates a service waiting for inbound connections, andESTABLISHEDmeans the session is still active. Therefore,TIME_WAIT (B)best indicates Tor Browser connections have been closed.

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：A
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.
質問 # 39
Benoy, a security professional at an organization, extracted Apache access log entries to view critical information about all the operations performed on a web server. The Apache access log extracted by Benoy is given below:
"10.10.10.10 - Jason [17/Aug/2019:00:12:34 +0300] "GET /images/content/bg_body_1.jpg HTTP/1.0" 500
1458"
Identify the HTTP status code in the Apache access log entry above that indicates the response was successful.
正解：C
解説：
In the Apache Combined/Custom access log format, the value immediately after the quoted request (here," GET ... HTTP/1.0") is theHTTP status codereturned by the server. In the provided entry, that field is500.
From a forensic analysis standpoint, recognizing field positions matters because investigators correlate client IPs, timestamps, requested resources, and server outcomes to reconstruct attack timelines and identify failed exploitation attempts or misconfigurations.
It is important to note thatsuccessful HTTP responses are typically in the 2xx range, most commonly200 (OK), while3xxindicates redirects,4xxindicates client-side errors (such as 404 Not Found), and5xxindicates server-side failures. Specifically,500represents anInternal Server Error, meaning the server encountered an unexpected condition and could not fulfill the request successfully.
The other options are not HTTP status codes in this entry:+0300is the timezone offset in the timestamp,1.0is the HTTP protocol version, and2019is part of the date. Therefore, the only HTTP status code present-and the correct choice among the options-is500 (B), even though it reflects an error rather than success.
質問 # 40
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.
正解：A
解説：
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).
質問 # 41
Wesley, a professional hacker, deleted a confidential file in a compromised system using the "/bin/rm/" command to deny access to forensic specialists.
Identify the operating system on which Don has performed the file carving act.
正解：C
解説：
The command path /bin/rm is a hallmark of UNIX/POSIX-style operating systems, where core userland utilities are commonly stored under directories such as /bin, /sbin, and /usr/bin. The utility rm (remove) is the standard UNIX command used to delete directory entries that reference a file's data blocks on disk. This layout and command structure do not match Windows, whichuses different filesystem conventions (drive letters, backslashes, and Windows-native executables) and does not provide /bin/rm as a native path. Android, while Linux-kernel-based, typically exposes shell utilities through environments like /system/bin (and newer systems may use toybox/busybox variants), not the classic /bin hierarchy expected on general-purpose UNIX systems. Between the remaining options, both Linux and macOS are UNIX-like and can include an rm command; however, in digital forensics training and examination contexts, the explicit reference to /bin/rm is most commonly used to indicate a Linux/UNIX command-line environment on a compromised host.
Therefore, the best single-choice answer from the provided options is Linux (D).
