NEW QUESTION # 58
A security team needs to prevent a remote code execution vulnerability. The vulnerability can be exploited only by sending '${ string in the HTTP request. WAF rule is blocking '${', but system engineers detect that attackers are executing commands on the host anyway. Which action should the security team recommend?
- A. Block incoming web traffic.
- B. Add two WAF rules to block 'S' and '{' characters separately.
- C. Deploy antimalware solution.
- D. Enable URL decoding on WAF.
Answer: D
Explanation:
When Web Application Firewalls (WAFs) are configured to block specific patterns (like${), attackers may bypass this using URL encoding (e.g.,%24%7B). In such cases, the WAF must decode these patterns before applying matching rules. EnablingURL decodingensures the WAF recognizes encoded payloads and applies protections appropriately. This is a recommended hardening strategy against bypass techniques for command injection and remote code execution.
Reference: Cisco CyberOps v1.2 Guide, Chapter on WAFs and Input Validation Techniques.

NEW QUESTION # 59
A financial company handling international transactions recently experienced a complex security incident The incident involves simultaneous DDoS attacks, suspected internal data leakage and the discovery of sophisticated malware implants that have remained dormant until triggered remotely During the incident it became clear that the current procedures are inadequate and plans to tackle issues were created on the go To counter this problem going forward, the IR team is developing an incident playbook to be used if a similar incident reoccurs Which set of elements of the playbook must be introduced?
- A. Introducing DDoS mitigation procedures, internal data leak investigations, and proactive malware containment
- B. Enhancing monitoring protocols, updating firewall rules, and automating traffic analysis tasks efficiently
- C. Establishing real-time collaboration procedures, increasing data encryption and revising access controls
- D. Engaging third-party cybersecurity experts expanding throat intelligence sharing and improving incident documentation
Answer: A
NEW QUESTION # 60 
Refer to the exhibit. A security analyst notices that a web application running on NGINX is generating an unusual number of log messages. The application is operational and reachable. What is the cause of this activity?
- A. directory fuzzing
- B. DDoS attack
- C. SQL injection
- D. botnet infection
Answer: A
Explanation:
The provided log file contains multiple HTTP GET requests attempting to access various directories and files on the web server such as:
* /balance
* /security
* /finance
* /secret
* /opt
* /fuzzer/admin
These requests appear to be sequential, systematically targeting commonly used file and directory paths. The response codes are mostly 404 (Not Found) and a few 301s, indicating that the requester is trying different permutations of paths to discover hidden or vulnerable endpoints. This behavior is consistent with directory fuzzing, a reconnaissance technique used by attackers (or automated tools) to map out web directory structures by sending a high volume of crafted requests to guess hidden or unlinked directories and files.
This is distinct from DDoS (which would manifest as volume-based access issues), SQL injection (which targets specific parameters within requests), or botnet infection (which generally involves command-and- control communication or massive traffic floods).

NEW QUESTION # 61
Refer to the exhibit.
What is occurring?
- A. The threat actor creates persistence by creating a repeatable task.
- B. Malware is modifying the registry keys.
- C. Obfuscated scripts are getting executed on the victim machine.
- D. RDP is used to move laterally to systems within the victim environment.
Answer: A
Explanation:
The command in the image uses schtasks /create with the ONLOGON schedule and System user context to execute test.exe. This is a well-documented persistence technique, where an attacker ensures that a malicious executable is launched automatically at each system logon. This kind of scheduled task creation aligns with persistence techniques in the MITRE ATT&CK framework (T1053).

NEW QUESTION # 62
A malware outbreak revealed that a firewall was misconfigured, allowing external access to the SharePoint server. What should the security team do next?
- A. Review and update all firewall rules and the network security policy
- B. Disable external IP communications on all firewalls
- C. Scan for and fix vulnerabilities on the firewall and server
- D. Harden the SharePoint server
Answer: A
Explanation:
The incident stems from a policy-level issue rather than a technical vulnerability. According to incident response best practices, the priority should be to review and update firewall rules and ensure that the network security policy aligns with the principle of least privilege and correct access segmentation.
NEW QUESTION # 63
An "unknown error code" is appearing on an ESXi host during authentication. An engineer checks the authentication logs but is unable to identify the issue. Analysis of the vCenter agent logs shows no connectivity errors. What is the next log file the engineer should check to continue troubleshooting this error?
- A. /var/log/syslog.log
- B. /var/log/general/log
- C. /var/log/vmksummary.log
- D. /var/log/shell.log
Answer: C
Explanation:
In VMware ESXi systems, the vmksummary.log file is responsible for capturing general system events, including uptime, reboot statistics, and key service-related issues. It serves as a valuable source for troubleshooting persistent or unexplained system behaviors.
The Cisco CyberOps study guide references log file paths used in system diagnostics and incident response, and for authentication-related issues on ESXi where standard logs don't yield insights, vmksummary.log is the recommended next source for identifying systemic service faults or anomalies.

NEW QUESTION # 64
Refer to the exhibit.
Which two actions should be taken as a result of this information? (Choose two.)
- A. Update the AV to block any file with hash "cf2b3ad32a8a4cfb05e9dfc45875bd70".
- B. Block all emails with pdf attachments.
- C. Block all emails sent from an @state.gov address.
- D. Block emails sent from [email protected] with an attached pdf file with md5 hash
"cf2b3ad32a8a4cfb05e9dfc45875bd70". - E. Block all emails with subject containing "cf2b3ad32a8a4cfb05e9dfc45875bd70".
Answer: A,D
Explanation:
The XML (STIX/CybOX format) details anemail-based threatindicator. Specifically:
* Theemail addresscontains "@state.gov" (not exact match, so blocking all @state.gov would be overbroad).
* Theattachment is a PDFfile with a specifiedMD5 hash: cf2b3ad32a8a4cfb05e9dfc45875bd70.
* Theattachment sizeis 87022 bytes.
From a threat mitigation perspective:
* Ais correct: Updating AV to block or flag files matching the malicious hash is a standard response.
* Dis correct: The email address context and hash together provide a precise rule for blocking-this prevents false positives.
Incorrect options:
* Boverreaches by blocking an entire domain without confirming threat context.
* Cwould stop all PDFs, which is impractical.
* Eis incorrect; there is no indication that the hash appears in the subject line.
NEW QUESTION # 65 
Refer to the exhibit. Which determination should be made by a security analyst?
- A. An email was sent with an attachment named "Final Report.doc".
- B. An email was sent with an attachment named "Final Report.doc.exe".
- C. An email was sent with an attachment named "Grades.doc.exe".
- D. An email was sent with an attachment named "Grades.doc".
Answer: B
NEW QUESTION # 66
Refer to the exhibit.
An engineer is analyzing a .LNK (shortcut) file recently received as an email attachment and blocked by email security as suspicious. What is the next step an engineer should take?
- A. Upload the file to a virus checking engine to compare with well-known viruses as the file is a virus disguised as a legitimate extension.
- B. Open the file in a sandbox environment for further behavioral analysis as the file contains a malicious script that runs on execution.
- C. Delete the suspicious email with the attachment as the file is a shortcut extension and does not represent any threat.
- D. Quarantine the file within the endpoint antivirus solution as the file is a ransomware which will encrypt the documents of a victim.
Answer: B
Explanation:
The metadata in the exhibit reveals a strong indicator that this .LNK file (shortcut) is malicious:
* The shortcut file is named "ds7002.pdf" but actually points to the execution of PowerShell:# Full path:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
* Arguments include:# -noni -ep bypass $z = '...'; indicating an attempt to run a PowerShell script with execution policy bypassed (a known tactic for fileless malware delivery).
* The file is masked as a PDF (common social engineering technique), and PowerShell execution via .
LNK is a signature technique used by many malware families to initiate second-stage payloads or scripts.
Given this, the correct and safest course of action is to:
# Open the .LNK file in a sandbox environment (D).
This enables safe behavioral analysis to observe what actions it attempts upon execution without endangering live systems.
Other options are inappropriate:
* A (ignoring the threat due to extension) is dangerous - .LNKs can trigger code.
* B (upload to virus engine) is only helpful for known malware and lacks behavioral context.
* C (quarantine) is preventive but not investigative - sandboxing provides visibility.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Threat Hunting and Malware Analysis," section covering shortcut (.LNK) based attacks, PowerShell-based threats, and sandbox behavioral analysis strategies.

NEW QUESTION # 68
What is an issue with digital forensics in cloud environments, from a security point of view?
- A. lack of logs
- B. network access instability
- C. no physical access to the hard drive
- D. weak cloud computer specifications
Answer: C
Explanation:
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.

- D. stepheorology
Answer: A
NEW QUESTION # 71
Refer to the exhibit.
Which type of code is being used?
- A. BASH
- B. Shell
- C. VBScript
- D. Python
Answer: D
Explanation:
The code in the exhibit is written in Python. Here's how we can confirm:
* The function definition uses Python syntax: def function_name(args):
* It uses the b64encode and decode functions - typical of Python's base64 module.
* Data structures such as dictionaries are used with curly braces (e.g., form_data = {entry1: enc1, ...}).
* The conditional syntax uses "if r.status_code == 200:" which is Pythonic.
* The request object "r = post(...)" and use of headers show standard use of the Python requests library.
This type of script is typical in exfiltration scenarios where encoded information is sent via a web form (in this case Google Forms), bypassing detection systems.
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Working with Malware and Exploit Scripts," which includes analysis of obfuscated and encoded scripts written in Python used for data exfiltration or C2 communication.
NEW QUESTION # 72
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. Confirm that the Microsoft Word license is valid and the application is updated to the latest version.
- B. Validate the frequency of PowerShell usage across all hosts to establish a baseline.
- C. Monitor the Microsoft Word startup times to ensure they align with business hours.
- D. Review the encoded PowerShell arguments to decode and determine the intent of the script.
Answer: D
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 # 73
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?
- A. tunneling
- B. encryption
- C. obfuscation
- D. poisoning
Answer: C
Explanation:
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.".
