質問 # 171
A security-team engineer must obtain the timestamps and detailed messages for failed-login events from a previously compromised Windows Server 2016 system. The engineer must construct a PowerShell script and export the events to a TXT file for analysis. The script must extract only events from the 72 hours immediately preceding its execution.
Drag and drop the code snippets onto the blanks to construct the script. Not all options are used.
正解：
解説：
Explanation:
(Get-Date).AddHours(-72) calculates the precise starting timestamp 72 hours before the script runs.
Get-WinEvent then applies a server-side filter to the Windows Security log for event ID 4625, which represents a failed account logon, and restricts results through StartTime=$startTime. Select-Object TimeCreated, Message retains the two fields required by the scenario. Finally, Out-File -FilePath .
\LogonFail.txt writes the formatted results to the specified text file; FilePath is the valid parameter, whereas Output is not. System is the wrong event log, and the other time expressions are not valid replacements for the required method call. This construction aligns with CBRFIR objective 2.5 on building PowerShell scripts to parse and search logs. Microsoft documents both Get-WinEvent - FilterHashtable and Out-File -FilePath.

Refer to the exhibit.
An engineer is analyzing a TCP stream in Wireshark after a suspicious email with a URL. What should be determined about the SMB traffic from this stream?
正解：D
解説：
The Wireshark output shows SMB protocol transactions, including NT Create AndX Response and Write AndX Response, indicating the transfer of files or objects. SMB (Server Message Block) is a protocol used for file sharing and printer access in Windows networks. The log does not indicate phishing or redirection behavior but rather normal SMB communication such as accessing files or shared resources.

質問 # 173
A threat actor attempts to avoid detection by turning data into a code that shifts numbers to the right four times. Which anti-forensics technique is being used?
正解：C
解説：
This scenario describes asubstitution cipher, where data is made unreadable or less recognizable without altering its functionality. According to the Cisco CyberOps Associate guide, obfuscation includes techniques such as shifting, encoding, and symbol manipulation to mask the true nature of data or code:
"A very well-known cipher, the Caesar cipher... shifts the letter of the alphabet by a fixed number... This technique is a form of data obfuscation used to bypass detection mechanisms.".
質問 # 174
Which tool should an investigator use to extract information about running processes from RAM?
正解：C
解説：
Volatility is purpose-built for extracting and interpreting artifacts from volatile-memory images. Its Windows pslist, psscan, and pstree capabilities can enumerate active processes, scan for terminated or unlinked process structures, and reconstruct parent-child relationships present when memory was acquired. Sleuth Kit and Autopsy primarily analyze file systems and disk images. The dd utility can acquire raw data, including a device image when used appropriately, but it does not itself interpret operating-system process structures.
SIFT is a broader forensic workstation that can contain numerous tools; it is not the most precise answer when Volatility is offered directly. Cisco includes memory-forensics tools within Fundamentals objective 1.6.d and explicitly lists Volatility among the tools whose purpose and functionality candidates must recognize under Forensics Techniques objective 2.6. The official Volatility documentation confirms that pslist lists processes present in a Windows memory image. Volatility pslist documentation
質問 # 175
Which information is provided about the object file by the "-h" option in the objdump line commandobjdump
-b oasys -m vax -h fu.o?
正解：B
解説：
The-hoption in theobjdumpcommand displayssection headersof an object file. According to general usage and command-line documentation, and also explained in digital forensics tools discussions in the CyberOps course, the header information includes details about the name, size, VMA, LMA, file offset, and alignment of each section in the object file. This helps analysts understand how data is stored and organized within compiled files during forensic examinations.
