NEW QUESTION # 342
During normal security monitoring activities, the following activity was observed:
cd C:\Users\Documents\HR\Employeestakeown/f .*
SUCCESS:
Which of the following best describes the potentially malicious activity observed?
Answer: B
Explanation:
The takeown command is used to take ownership of a file or folder that previously was denied access to the current user or group. The activity observed indicates that someone has taken ownership of all files and folders under the C:\Users\Documents\HR\Employees directory, which may contain sensitive or confidential information. This could be a sign of unauthorized privileges, as the user or group may not have the legitimate right or need to access those files or folders.
Taking ownership of files or folders could also enable the user or group to modify or delete them, which could affect the integrity or availability of the data.
NEW QUESTION # 343
Which of the following attributes is part of the Diamond Model of Intrusion Analysis?
Answer: A
Explanation:
The Diamond Model of Intrusion Analysis includes four key attributes (or vertices) to describe and analyze cyber intrusion events. These attributes are: Adversary: The entity or attacker responsible for the intrusion. Capability: The tools, techniques, and resources used by the adversary to carry out the attack. Infrastructure: The physical and virtual resources used by the adversary, such as command-and-control servers or phishing domains. Victim: The target of the intrusion, including individuals, organizations, or systems.
NEW QUESTION # 344
During an incident involving phishing, a security analyst needs to find the source of the malicious email. Which of the following techniques would provide the analyst with this information?
Answer: B
Explanation:
Header analysis is the technique of examining the metadata of an email, such as the sender, recipient, date, subject, and routing information. It can help to identify the source of a malicious email by revealing the IP address and domain name of the originator, as well as any spoofing or redirection attempts.
NEW QUESTION # 345
A Chief Information Security Officer wants to map all the attack vectors that the company faces each day. Which of the following recommendations should the company align their security controls around?
Answer: B
Explanation:
The correct answer is D. MITRE ATT&CK.
MITRE ATT&CK is a framework that maps the tactics, techniques, and procedures (TTPs) of various threat actors and groups, based on real-world observations and dat
a. MITRE ATT&CK can help a Chief Information Security Officer (CISO) to map all the attack vectors that the company faces each day, as well as to align their security controls around the most relevant and prevalent threats. MITRE ATT&CK can also help the CISO to assess the effectiveness and maturity of their security posture, as well as to identify and prioritize the gaps and improvements .
The other options are not the best recommendations for mapping all the attack vectors that the company faces each day. OSSTMM (Open Source Security Testing Methodology Manual) (A) is a methodology that provides guidelines and best practices for conducting security testing and auditing, but it does not map the TTPs of threat actors or groups. Diamond Model of Intrusion Analysis (B) is a model that analyzes the relationships and interactions between four elements of an intrusion: adversary, capability, infrastructure, and victim. The Diamond Model can help understand the characteristics and context of an intrusion, but it does not map the TTPs of threat actors or groups. OWASP (Open Web Application Security Project) is a project that provides resources and tools for improving the security of web applications, but it does not map the TTPs of threat actors or groups.
NEW QUESTION # 346
During a routine review of DNS logs, a security analyst observes that Host X has been making frequent DNS requests to domains with random alphanumeric strings, such as ajd8ekthj.xyz. IPS anomaly rules are blocking these domains. This behavior started shortly after a new software installation on the host. Which of the following should the analyst do first to determine whether Host X has been compromised?
Answer: D
Explanation:
The correct answer is D because the analyst should first validate whether the suspicious DNS domains are malicious or legitimate. Random-looking DNS domains may indicate malware using a domain generation algorithm (DGA) for command-and-control, but they can also appear in legitimate services such as content delivery networks or software update mechanisms. Therefore, the best first step is to enrich the DNS indicators using threat intelligence and reputation sources.
Exact supporting extract: the CySA+ All-in-One guide explains that DNS tunneling and abnormal DNS queries may be used for command-and-control or exfiltration. It also states that high-entropy domains appear random or "gibberish" to humans and that malware may use DGAs for C2 communication. However, it also warns that computer-generated domain names can have legitimate uses in content delivery networks.
The same guide explains that threat research should help answer questions such as whether an artifact is benign, whether anyone has seen it before, and why it is present in the system. It further explains that reputation data for domains, URLs, and IP addresses helps determine whether activity is associated with malware, phishing, C2, or data exfiltration.
Why the other options are incorrect:
A is incorrect because allowing the domains without validation could permit C2 or data exfiltration.
B is incorrect because reinstalling the software does not determine whether the DNS activity is malicious.
C is incorrect because blocking all outbound connections is a containment action, not the best first investigative step when the analyst is still determining whether compromise occurred.
D is correct because threat intelligence/reputation lookup is the most appropriate first validation step for suspicious DNS indicators.
