Which of the following PIDs is most likely to contribute to data exfiltration?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
* PID 2264 (bash running as root) is suspicious because:
* It has elevated privileges (root user).
* Bash (command-line shell) is running with high CPU usage (14.0%), which is unusual unless actively being used.
* If unauthorized, an attacker could be exfiltrating data via command-line methods like scp, wget, or custom scripts.
Why Not Other Options?
* B (34218 - Xorg) # Xorg is a display server for GUI; no signs of exfiltration.
* C (34834 - Cinnamon) # Cinnamon is a desktop environment, not a threat.
* D (35963 - xrdp) # xrdp is a remote desktop service, expected behavior.

NEW QUESTION # 45
A security analyst needs to prioritize vulnerabilities for patching. Given the following vulnerability and system information:

Which of the following systems should the analyst patch first?

A. System 2
B. System 4
C. System 3
D. System 6
E. System 5
F. System 1

Answer: B

Explanation:
When prioritizing vulnerabilities, analysts consider the CVSS score, whether the system is internet-facing, and if sensitive data is involved. The primary goal is to mitigate the most exploitable and impactful risks first.
Let's break down the key components:
* Attack Vector (AV): Whether the attack can be launched remotely (N = Network) or locally (L = Local).
* Attack Complexity (AC): The difficulty of executing the attack (L = Low, H = High).
* Privileges Required (PR): The level of access needed for exploitation (N = None, L = Low, H = High).
* User Interaction (UI): Whether user interaction is required for the attack (N = No, R = Required).
* Scope (S): Whether the attack affects other systems (C = Changed, U = Unchanged).
* Confidentiality (C), Integrity (I), Availability (A): The impact level (H = High, L = Low, N = None).
Evaluating Each System:
* System 1 (CVSS: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H)
* Internet-facing #
* No sensitive data #
* High confidentiality and availability impact #
* Moderate risk due to requiring low privileges
* System 2 (CVSS: AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H)
* Not internet-facing #
* No sensitive data #
* Lower priority since it's local-only
* System 3 (CVSS: AV:P/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:L)
* Internet-facing #
* Contains sensitive data #
* But very low likelihood of exploit (requires physical access, high privileges, user interaction)
* Lower priority due to high attack complexity
* System 4 (CVSS: AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:H)
* Internet-facing #
* No sensitive data #
* No privileges required for exploitation #
* High impact on confidentiality and availability #
* Most critical due to remote exploitability and system-wide scope
* System 5 (CVSS: AV:L/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:N)
* Internet-facing #
* Contains sensitive data #
* But requires high privileges, high attack complexity, and user interaction
* Lower priority than System 4
* System 6 (CVSS: AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H)
* Not internet-facing #
* No sensitive data #
* Same as System 2 (low priority due to being local-only)
Final Decision: Patch System 4 First
System 4 is the most critical because:
* It is internet-facing (higher exposure).
* It has a high CVSS score.
* It requires no privileges (easy to exploit).
* It has system-wide scope impact (can affect other systems).
Thus, it should be patched first to minimize security risks.

NEW QUESTION # 46
During a training exercise, a security analyst must determine the vulnerabilities to prioritize. The analyst reviews the following vulnerability scan output:

Which of the following issues should the analyst address first?

A. less command allows for escape exploit via terminal
B. Allows anonymous read access via any FTP connection
C. Allows anonymous read access to /etc/passwd
D. Microsoft Defender security definition updates disabled

Answer: C

NEW QUESTION # 47
A security analyst is reviewing the following alert that was triggered by FIM on a critical system:

Which of the following best describes the suspicious activity that is occurring?

A. A network drive was added to allow exfiltration of data
B. A new program has been set to execute on system start
C. The host firewall on 192.168.1.10 was disabled.
D. A fake antivirus program was installed by the user.

Answer: B

Explanation:
A new program has been set to execute on system start is the most likely cause of the suspicious activity that is occurring, as it indicates that the malware has modified the registry keys of the system to ensure its persistence. File Integrity Monitoring (FIM) is a tool that monitors changes to files and registry keys on a system and alerts the security analyst of any unauthorized or malicious modifications. The alert triggered by FIM shows that the malware has created a new registry key under the Run subkey, which is used to launch programs automatically when the system starts. The new registry key points to a file named "update.exe" in the Temp folder, which is likely a malicious executable disguised as a legitimate update file. Official References:

NEW QUESTION # 48
A virtual web server in a server pool was infected with malware after an analyst used the internet to research a system issue. After the server was rebuilt and added back into the server pool, users reported issues with the website, indicating the site could not be trusted. Which of the following is the most likely cause of the server issue?

A. The malware infected all the web servers in the pool.
B. The digital certificate on the web server was self-signed
C. The server was configured to use SSI- to securely transmit data
D. The server was supporting weak TLS protocols for client connections.

Answer: B

Explanation:
A digital certificate is a document that contains the public key and identity information of a web server, and is signed by a trusted third-party authority called a certificate authority (CA). A digital certificate allows the web server to establish a secure connection with the clients using the HTTPS protocol, and also verifies the authenticity of the web server. A self-signed certificate is a digital certificate that is not signed by a CA, but by the web server itself. A self-signed certificate can cause issues with the website, as it may not be trusted by the clients or their browsers. Clients may receive warnings or errors when trying to access the website, indicating that the site could not be trusted or that the connection is not secure. Official References:
