NEW QUESTION # 55
During a routine inspection of system logs, a security analyst notices an entry where Microsoft Word initiated a PowerShell command with encoded arguments. Given that the user's role does not involve scripting or advanced document processing, which action should the analyst take to analyze this output for potential indicators of compromise?
- A. Monitor the Microsoft Word startup times to ensure they align with business hours.
- B. Confirm that the Microsoft Word license is valid and the application is updated to the latest version.
- C. Review the encoded PowerShell arguments to decode and determine the intent of the script.
- D. Validate the frequency of PowerShell usage across all hosts to establish a baseline.
Answer: C
Explanation:
According to theCyberOps Technologies (CBRFIR) 300-215 study guidecurriculum, when analyzing suspicious behavior-especially when scripts or shell commands are executed from applications like Word (which is uncommon)-the encoded PowerShell payload must be decoded to determine if malicious intent is present. Deobfuscation is a critical step in identifying command-and-control behavior, persistence, or malware execution paths.

NEW QUESTION # 59
An engineer is investigating a ticket from the accounting department in which a user discovered an unexpected application on their workstation. Several alerts are seen from the intrusion detection system of unknown outgoing internet traffic from this workstation. The engineer also notices a degraded processing capability, which complicates the analysis process. Which two actions should the engineer take? (Choose two.)
- A. Format the workstation drives.
- B. Restore to a system recovery point.
- C. Take an image of the workstation.
- D. Disconnect from the network.
- E. Replace the faulty CPU.
Answer: C,D
Explanation:
When suspicious activity is detected on a workstation, immediate steps need to be taken to preserve evidence and prevent further compromise:
* Disconnecting the system from the network (C)is crucial to stop potential exfiltration of data or ongoing communications with a command-and-control server. This isolation prevents further spread or damage while preserving the state of the compromised system for further investigation.
* Taking an image of the workstation (E)is part of the forensics acquisition process. It involves creating a bit-by-bit copy of the system's disk, which preserves all evidence in its current state. This allows for thorough forensic analysis without affecting the original evidence.
These steps align with the best practices outlined in the incident response and forensics processes (as described in theCyberOps Technologies (CBRFIR) 300-215 study guide). Specifically, in theIdentification and Containmentphases of the incident response cycle, it's emphasized that isolating the system and preserving evidence through imaging are critical to ensuring both containment of the threat and successful forensic investigation.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter: Understanding the Security Incident Response Process, Identification and Containment Phases, page 102-104.
NEW QUESTION # 60
During a routine security audit, an organization's security team detects an unusual spike in network traffic originating from one of their internal servers. Upon further investigation, the team discovered that the server was communicating with an external IP address known for hosting malicious content. The security team suspects that the server may have been compromised. As the incident response process begins, which two actions should be taken during the initial assessment phase of this incident? (Choose two.)
- A. Review the organization's network logs for any signs of intrusion.
- B. Notify law enforcement agencies about the incident.
- C. Conduct a comprehensive forensic analysis of the server hard drive.
- D. Interview employees who have access to the server.
- E. Disconnect the compromised server from the network.
Answer: A,E
Explanation:
During the initial phase of incident response, the two key actions are:
* Disconnecting the server (B) to contain the threat and prevent lateral movement or further exfiltration.
* Reviewing network logs (E) to understand the timeline and scope of the attack.
These are emphasized in the containment and detection stages of the incident response lifecycle outlined in NIST 800-61 and covered in the Cisco CyberOps training.

NEW QUESTION # 61
What can the blue team achieve by using Hex Fiend against a piece of malware?
- A. Read the hex data and transmognify into a readable ELF format
- B. Read the hex data and decrypt payload via access key.
- C. Use the hex data to define patterns in VARA rules.
- D. Use the hex data to modify BE header to read the file.
Answer: C
Explanation:
Hex Fiend is a hex editor that allows analysts to examine the raw byte content of files. One key use case is identifying and extracting byte-level patterns or signatures that can be translated into YARA rules for detecting malware. These hex patterns can be used to define precise signature-based detections.
NEW QUESTION # 62
Refer to the exhibit.
An HR department submitted a ticket to the IT helpdesk indicating slow performance on an internal share server. The helpdesk engineer checked the server with a real-time monitoring tool and did not notice anything suspicious. After checking the event logs, the engineer noticed an event that occurred 48 hours prior. Which two indicators of compromise should be determined from this information? (Choose two.)
- A. unauthorized system modification
- B. denial of service attack
- C. privilege escalation
- D. malware outbreak
- E. compromised root access
Answer: A,D
Explanation:
According to the event log, a suspicious service was installed (DIAOHHNMPMMRgji) with a service file pointing to a remote share (\\127.0.0.1\admin$\EqnBqKWm.exe). This type of activity strongly suggests:
* A. Unauthorized system modification: Installation of a service without proper authorization, especially with a random or obfuscated name, directly fits the description of system modification. The use of admin$ (administrative share) further implies this wasn't part of standard operations.
* E. Malware outbreak: The use of a service that points to an executable with a seemingly random name and the demand start configuration indicate a potential backdoor or remote-controlled malware. As stated in the Cisco CyberOps Associate guide, event ID 7045 with unusual service names or file paths is a strong Indicator of Compromise (IoC) for malware or persistence mechanisms.
Options like privilege escalation or DoS are not directly evidenced in the event log shown. There's no indication that the LocalSystem account was elevated beyond its default, nor that system resources were overwhelmed (as would be typical in DoS).
NEW QUESTION # 63
An analyst finds .xyz files of unknown origin that are large and undetected by antivirus. What action should be taken next?
- A. Isolate the files and perform a deeper heuristic analysis to detect potential unknown malware or data exfiltration payloads.
- B. Rename the file extensions to .txt to enable easier opening and review by team members.
- C. Move the files to a less secure network segment for analysis.
- D. Delete the files immediately to prevent potential risks.
Answer: A
Explanation:
The safest and most effective approach is to isolate the files and subject them to heuristic and behavioral analysis. This can reveal obfuscated malware or unauthorized data storage techniques, even if signature-based antivirus fails to flag them.
NEW QUESTION # 64
Refer to the exhibit.
What should an engineer determine from this Wireshark capture of suspicious network traffic?
- A. There are signs of SYN flood attack, and the engineer should increase the backlog and recycle the oldest half-open TCP connections.
- B. There are signs of ARP spoofing, and the engineer should use Static ARP entries and IP address-to- MAC address mappings as a countermeasure.
- C. There are signs of a malformed packet attack, and the engineer should limit the packet size and set a threshold of bytes as a countermeasure.
- D. There are signs of a DNS attack, and the engineer should hide the BIND version and restrict zone transfers as a countermeasure.
Answer: A
Explanation:
In the provided Wireshark capture, we see multiple TCP SYN packets being sent from different source IP addresses to the same destination IP address(192.168.1.159:80)within a short time window. These SYN packets do not show a corresponding SYN-ACK or ACK response, indicating that these TCP connection requests are not being completed.
This pattern is indicative of aSYN flood attack, a type of Denial of Service (DoS) attack. In this attack, a malicious actor floods the target system with a high volume of TCP SYN requests, leaving the target's TCP connection queue (backlog) filled with half-open connections. This can exhaust system resources, causing legitimate connection requests to be denied or delayed.
Thecountermeasurefor this scenario, as highlighted in theCyberOps Technologies (CBRFIR) 300-215 study guideunderNetwork-Based Attacks and TCP SYN Flood Attacks, involves:
* Increasing the backlog queue: This allows the server to hold more half-open connections.
* Recycling the oldest half-open connections: This ensures that legitimate connections have a chance to be established if the backlog fills up.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter 5: Identifying Attack Methods, SYN Flood Attack section, page 146-148.
NEW QUESTION # 65
Refer to the exhibit.
What is occurring?
- A. WAF detected code injection.
- B. The request was redirected.
- C. An attacker attempted SQL injection.
- D. The requested page was not found.
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
The log entry contains the following key elements:
* The timestamp:(04/Jan/2022:20:18:06 +0000)
* HTTP method and URI:"GET /%60%60%60%60%60%60/ HTTP/2.0"
* HTTP status code:404
* User-Agent:Mozilla/5.0 ... Firefox/95.0
The status code404indicates that the requested resource was not found on the server. This is a standard HTTP response that signifies the server could not locate the requested URI (in this case, likely due to a malformed or invalid path/\`````/, where%60is the URL-encoded form of the backtick character "").
There is no clear evidence of SQL injection, WAF detection, or redirection in this log. The use of encoded backticks may suggest probing behavior, but the log does not show a definitive attack signature.
Therefore, the correct interpretation is:
D: The requested page was not found.
