問題 #81
Refer to the exhibit.
Registry Key Activity
MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN modified (1)
MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUNONCE created (1),
modified (2)
MACHINE\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\WINLOGON modified (1) MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\SESSION MANAGER\ENVIRONMENT modified (1) MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES\EXPLORER modified (2) MACHINE\SOFTWARE\MICROSOFT\COMMAND PROCESSOR modified (1) For user S-5-21-0533532869, which registry key shows evidence of persistence through a newly created autorun entry?

A. RunOnce
B. Run
C. Winlogon
D. Environment

答案：A

解題說明：
The RunOnce row is the only autorun-related key marked as newly created as well as modified.
Windows processes values under RunOnce when a user logs on and normally deletes each value after it is invoked. An attacker can therefore create a value containing a malicious command so that the payload executes automatically at the next logon, providing boot-or-logon autostart persistence. The ordinary Run key is also an autorun location, but the exhibit records only a modification, not the newly created entry specified in the question. Winlogon and Environment can be security-relevant, yet their displayed activity does not match the required evidence. Option D is consequently the precise artifact- based conclusion. This supports CBRFIR objectives 2.3 and 3.9 concerning host artifacts and indicators. Microsoft documents the behavior and locations of the Run and RunOnce keys .

問題 #82
Refer to the exhibit. What encoding technique is shown?
QmFzZTY0IGVuY29kaW5nIGlzIGEgd2lkZWx5IHVzZWQgbWV0aG9kIGZvciBjb252ZXJ0aW5nIGJpbmFye

A. JavaScript
B. Base64
C. ASCII85
D. Hexadecimal

答案：B

解題說明：
The exhibit is Base64-encoded text. Its character distribution fits the Base64 alphabet, and the length is consistent with four-character encoding groups. Decoding it yields an English explanation beginning, "Base64 encoding is a widely used method for converting binary data into a text format." Hexadecimal would use only digits 0-9 and letters A-F, usually in two-character byte pairs. ASCII85 permits a broader punctuation range and typically has a different visual pattern. JavaScript is a programming language, not the binary-to-text representation shown. Base64 is encoding rather than encryption: it changes representation and is trivially reversible, so analysts should decode it before inspecting a payload or deciding whether the content is malicious. This skill is explicitly included in CBRFIR Fundamentals objective 1.4, which covers recognition of Base64, hexadecimal, and other obfuscation techniques. Cisco CBRFIR v1.2 exam topics

問題 #83
What is an issue with digital forensics in cloud environments, from a security point of view?

A. no physical access to the hard drive
B. network access instability
C. weak cloud computer specifications
D. lack of logs

答案：A

解題說明：
One of the primary challenges of cloud forensics is the inability to physically access the underlying hardware (e.g., the hard drives storing VM or container data). This restricts investigators from performing traditional disk imaging and handling procedures, which are crucial for maintaining evidence integrity. This limitation is widely recognized in cloud forensics frameworks.
Correct answer: C. no physical access to the hard drive.

問題 #84
An incident response team is recommending changes after analyzing a recent compromise in which:
a large number of events and logs were involved;
team members were not able to identify the anomalous behavior and escalate it in a timely manner; several network systems were affected as a result of the latency in detection; security engineers were able to mitigate the threat and bring systems back to a stable state; and the issue reoccurred shortly after and systems became unstable again because the correct information was not gathered during the initial identification phase.
Which two recommendations should be made for improving the incident response process? (Choose two.)

A. Formalize reporting requirements and responsibilities to update management and internal stakeholders throughout the incident-handling process effectively.
B. Improve the mitigation phase to ensure causes can be quickly identified, and systems returned to a functioning state.
C. Allocate additional resources for the containment phase to stabilize systems in a timely manner and reduce an attack's breadth.
D. Modify the incident handling playbook and checklist to ensure alignment and agreement on roles, responsibilities, and steps before an incident occurs.
E. Implement an automated operation to pull systems events/logs and bring them into an organizational context.

答案：D,E

問題 #85
What is the goal of an incident response plan?

A. to contain an attack and prevent it from spreading
B. to determine security weaknesses and recommend solutions
C. to identify critical systems and resources in an organization
D. to ensure systems are in place to prevent an attack

答案：A
