Sample Question 1 — Malware Threats

During a penetration test, you discover a system being affected by a malware that encrypts files until a ransom is paid. Which of the following steps should you take first to ethically handle this situation?

  1. A. Immediately pay the ransom to restore access to the files.
  2. B. Inform the client and isolate the infected system from the network. (Correct answer)
  3. C. Attempt to decrypt the files using a known malware decryption tool.
  4. D. Create backups of the encrypted files and continue testing.

Correct answer: B

Explanation: Informing the client and isolating the system is the first step to prevent further infection spread and to ensure the client is aware of the situation. Paying the ransom is not recommended due to ethical and practical reasons. Attempting decryption or creating backups should follow after containment.

Sample Question 2 — Malware Threats

You are tasked with testing a company's defenses against Trojan malware. Which tool would be most effective in simulating this kind of threat?

  1. A. Nmap
  2. B. Nessus
  3. C. Metasploit (Correct answer)
  4. D. Wireshark

Correct answer: C

Explanation: Metasploit is widely used for simulating various types of malware attacks, including Trojans, due to its comprehensive exploit database and payload capabilities. Nmap and Nessus are primarily used for network scanning and vulnerability assessment, while Wireshark is used for packet analysis.

Sample Question 3 — Malware Threats

While performing a security assessment, you suspect that a system has been compromised by a rootkit. What is the most effective method to confirm your suspicion?

  1. A. Check the running processes for any unusual activity.
  2. B. Use a rootkit detection tool from a known trusted source. (Correct answer)
  3. C. Reboot the system and perform a normal virus scan.
  4. D. Disconnect the system from the network and watch for changes.

Correct answer: B

Explanation: Using a rootkit detection tool is the most effective way to identify hidden rootkits, as these tools are specifically designed to detect hidden processes and files. Checking processes can be helpful but may not reveal rootkits. Rebooting can help but might also make the rootkit harder to detect if it alters its behavior. Simply disconnecting the system will not directly lead to detection.

Sample Question 4 — Malware Threats

While analyzing network traffic, you detect a potential Command and Control (C&C) communication. Which action should you take to confirm this is a malware activity?

  1. A. Block the suspect IP address immediately.
  2. B. Capture and analyze the traffic data for suspicious patterns. (Correct answer)
  3. C. Shutdown the network to prevent further communication.
  4. D. Look for increased network latency and bandwidth usage.

Correct answer: B

Explanation: Capturing and analyzing traffic data allows for identifying specific patterns and behaviors indicative of C&C communication. Immediate blocking or shutdown actions might be premature without evidence. Increased latency and bandwidth can occur for various reasons and do not specifically confirm malware activity.

Sample Question 5 — Malware Threats

A client reports that their systems are frequently crashing, and you suspect malware interference. What is the best course of action to identify the cause?

  1. A. Run a full system scan using an up-to-date antivirus program. (Correct answer)
  2. B. Check system logs for any unusual errors or warnings.
  3. C. Reformat the system to eliminate any malware traces.
  4. D. Reboot the system in safe mode and observe behavior.

Correct answer: A

Explanation: Running a full system scan is effective in identifying and potentially removing known malware. Checking logs and rebooting in safe mode can provide more information but will not directly identify malware. Reformatting is drastic and should be a last resort after confirming malware presence.

Sample Question 6 — Malware Threats

As part of vulnerability assessment, you discover that several systems have outdated software potentially vulnerable to malware. Which strategy should you prioritize to mitigate this risk?

  1. A. Deploy the latest security patches across all systems. (Correct answer)
  2. B. Implement an Intrusion Detection System (IDS).
  3. C. Isolate the systems from the network until they are updated.
  4. D. Develop a malware response plan for future incidents.

Correct answer: A

Explanation: Deploying the latest patches addresses known vulnerabilities and reduces the risk of malware exploitation. While implementing an IDS and developing a response plan are important, they do not directly remediate existing vulnerabilities. Isolation is a temporary measure and not a long-term solution.
