Question 1

Joe works as a threat intelligence analyst with Xsecurity Inc. He is assessing the TI program by comparing the project results with the original objectives by reviewing project charter. He is also reviewing the list of expected deliverables to ensure that each of those is delivered to an acceptable level of quality.

Identify the activity that Joe is performing to assess a TI program's success or failure.



Answer : D

By assessing the Threat Intelligence (TI) program through a comparison of project results with the original objectives, and by ensuring that all expected deliverables have been produced to an acceptable quality level, Joe is conducting a gap analysis. Gap analysis involves identifying the difference between the current state and the desired state or objectives, in this case, the outcomes of the TI program versus its intended goals as outlined in the project charter. This process allows for the assessment of what was successful, what fell short, and where improvements can be made, thereby evaluating the program's overall effectiveness and identifying areas for future enhancement.

Question 2

A threat analyst obtains an intelligence related to a threat, where the data is sent in the form of a connection request from a remote host to the server. From this data, he obtains only the IP address of the source and destination but no contextual information. While processing this data, he obtains contextual information stating that multiple connection requests from different geo-locations are received by the server within a short time span, and as a result, the server is stressed and gradually its performance has reduced. He further performed analysis on the information based on the past and present experience and concludes the attack experienced by the client organization.

Which of the following attacks is performed on the client organization?



Answer : C

The attack described, where multiple connection requests from different geo-locations are received by a server within a short time span leading to stress and reduced performance, is indicative of a Distributed Denial-of-Service (DDoS) attack. In a DDoS attack, the attacker floods the target's resources (such as a server) with excessive requests from multiple sources, making it difficult for the server to handle legitimate traffic, leading to degradation or outright unavailability of service. The use of multiple geo-locations for the attack sources is a common characteristic of DDoS attacks, making them harder to mitigate. Reference:

Question 3

John, a professional hacker, is trying to perform APT attack on the target organization network. He gains access to a single system of a target organization and tries to obtain administrative login credentials to gain further access to the systems in the network using various techniques.

What phase of the advanced persistent threat lifecycle is John currently in?



Answer : C

The phase described where John, after gaining initial access, is attempting to obtain administrative credentials to further access systems within the network, is known as the 'Expansion' phase of an Advanced Persistent Threat (APT) lifecycle. This phase involves the attacker expanding their foothold within the target's environment, often by escalating privileges, compromising additional systems, and moving laterally through the network. The goal is to increase control over the network and maintain persistence for ongoing access. This phase follows the initial intrusion and sets the stage for establishing long-term presence and eventual data exfiltration or other malicious objectives. Reference:

Question 4

Which of the following components refers to a node in the network that routes the traffic from a workstation to external command and control server and helps in identification of installed malware in the network?



Answer : B

A gateway in a network functions as a node that routes traffic between different networks, such as from a local network to the internet. In the context of cyber threats, a gateway can be utilized to monitor and control the data flow to and from the network, helping in the identification and analysis of malware communications, including traffic to external command and control (C2) servers. This makes it an essential component in detecting installed malware within a network by observing anomalies or unauthorized communications at the network's boundary. Unlike repeaters, hubs, or network interface cards (NICs) that primarily facilitate network connectivity without analyzing the traffic, gateways can enforce security policies and detect suspicious activities.

Question 5

Henry. a threat intelligence analyst at ABC Inc., is working on a threat intelligence program. He was assigned to work on establishing criteria for prioritization of intelligence needs and requirements.

Which of the following considerations must be employed by Henry to prioritize intelligence requirements?



Answer : A

When prioritizing intelligence requirements, it is crucial to understand the frequency and impact of various threats. This approach helps in allocating resources effectively, focusing on threats that are both likely to occur and that would have significant consequences if they did. By assessing threats based on these criteria, Henry can ensure that the threat intelligence program addresses the most pressing and potentially damaging threats first, thereby enhancing the organization's security posture. This prioritization is essential for effective threat management and for ensuring that the most critical threats are addressed promptly. Reference:

Question 6

An attacker instructs bots to use camouflage mechanism to hide his phishing and malware delivery locations in the rapidly changing network of compromised bots. In this particular technique, a single domain name consists of multiple IP addresses.

Which of the following technique is used by the attacker?



Answer : D

Fast-Flux DNS is a technique used by attackers to hide phishing and malware distribution sites behind an ever-changing network of compromised hosts acting as proxies. It involves rapidly changing the association of domain names with multiple IP addresses, making the detection and shutdown of malicious sites more difficult. This technique contrasts with DNS zone transfers, which involve the replication of DNS data across DNS servers, or Dynamic DNS, which typically involves the automatic updating of DNS records for dynamic IP addresses, but not necessarily for malicious purposes. DNS interrogation involves querying DNS servers to retrieve information about domain names, but it does not involve hiding malicious content. Fast-Flux DNS specifically refers to the rapid changes in DNS records to obfuscate the source of the malicious activity, aligning with the scenario described. Reference:

Question 7

Jian is a member of the security team at Trinity, Inc. He was conducting a real-time assessment of system activities in order to acquire threat intelligence feeds. He acquired feeds from sources like honeynets, P2P monitoring. infrastructure, and application logs.

Which of the following categories of threat intelligence feed was acquired by Jian?



Answer : A

Internal intelligence feeds are derived from data and information collected within an organization's own networks and systems. Jian's activities, such as real-time assessment of system activities and acquiring feeds from honeynets, P2P monitoring, infrastructure, and application logs, fall under the collection of internal intelligence feeds. These feeds are crucial for identifying potential threats and vulnerabilities within the organization and form a fundamental part of a comprehensive threat intelligence program. They contrast with external intelligence feeds, which are sourced from outside the organization and include information on broader cyber threats, trends, and TTPs of threat actors. Reference:
