Scenario practice questions

A threat intelligence analyst is reviewing a report that describes an adversary's operational approach using a model that maps phases from reconnaissance through to achieving the final mission. The report specifically highlights that the adversary spent weeks performing open-source research on employees and technical infrastructure before any exploitation attempt. In the Lockheed Martin Cyber Kill Chain, which phase is being described?

Trap 1: Exploitation

Exploitation is the phase where the adversary leverages a vulnerability to execute code on the target system. The scenario explicitly states the adversary performed research before any exploitation attempt, meaning exploitation has not yet occurred. The activity described is purely information gathering, not vulnerability triggering or code execution.

Trap 2: Weaponization

Weaponization is the phase where the adversary couples a remote access Trojan with an exploit into a deliverable payload. In this scenario, no payload construction or tool coupling is mentioned; the adversary is only gathering information about employees and infrastructure. Weaponization occurs after reconnaissance and requires an actual artifact to be built, which is not described here.

Trap 3: Delivery

Delivery is the phase where the adversary transmits the weaponized payload to the target, such as via phishing email or USB drive. The scenario describes research and information gathering, not the transmission of any payload. Delivery requires a weaponized artifact to be sent, which has not yet been created according to the scenario details.

A
Reconnaissance
Reconnaissance is the first phase of the Cyber Kill Chain and involves harvesting information about the target, such as employee names, email addresses, and technical infrastructure. The scenario explicitly states the adversary spent weeks performing open-source research on employees and infrastructure before any exploitation, which maps directly to this phase. No payload, delivery, or exploitation activity is described, confirming this is the correct phase.
B
Exploitation
Why it fails: Exploitation is the phase where the adversary leverages a vulnerability to execute code on the target system. The scenario explicitly states the adversary performed research before any exploitation attempt, meaning exploitation has not yet occurred. The activity described is purely information gathering, not vulnerability triggering or code execution.
C
Weaponization
Why it fails: Weaponization is the phase where the adversary couples a remote access Trojan with an exploit into a deliverable payload. In this scenario, no payload construction or tool coupling is mentioned; the adversary is only gathering information about employees and infrastructure. Weaponization occurs after reconnaissance and requires an actual artifact to be built, which is not described here.
D
Delivery
Why it fails: Delivery is the phase where the adversary transmits the weaponized payload to the target, such as via phishing email or USB drive. The scenario describes research and information gathering, not the transmission of any payload. Delivery requires a weaponized artifact to be sent, which has not yet been created according to the scenario details.

Question 2mediummulti select

An analyst is using the MITRE ATT&CK framework to categorize adversary behaviors observed during an incident. The analyst notes that the attacker used a scheduled task to maintain access and also encrypted files on a file share to disrupt operations. Which two ATT&CK tactics do these behaviors represent? (Choose two.)

Trap 1: Discovery

Discovery involves techniques to explore the environment, such as network scanning or file and directory discovery. The scenario does not describe any exploratory activities; the attacker already had access and used a scheduled task and file encryption. These actions are about maintaining access and causing disruption, not gathering information. Therefore, Discovery is not a correct classification for the observed behaviors.

Trap 2: Privilege Escalation

Privilege Escalation involves techniques to gain higher-level permissions, such as exploiting a vulnerability or abusing misconfigured services. The scenario describes a scheduled task for maintaining access and file encryption for disruption, neither of which necessarily involves elevating privileges. While scheduled tasks can sometimes be used for privilege escalation, the stated purpose here is persistence, not escalation. Therefore, this tactic does not fit the observed behaviors.

Trap 3: Defense Evasion

Defense Evasion covers techniques to avoid detection, such as obfuscation or disabling security tools. The scenario does not mention any attempt to evade defenses; the attacker used a scheduled task and encrypted files. While encryption might incidentally hinder analysis, the primary goal of encrypting files for disruption is Impact, not Defense Evasion. Thus, this tactic is not supported by the described behaviors.

A
Discovery
Why it fails: Discovery involves techniques to explore the environment, such as network scanning or file and directory discovery. The scenario does not describe any exploratory activities; the attacker already had access and used a scheduled task and file encryption. These actions are about maintaining access and causing disruption, not gathering information. Therefore, Discovery is not a correct classification for the observed behaviors.
B
Persistence
Persistence consists of techniques that adversaries use to maintain their foothold in a network, such as creating scheduled tasks, services, or registry run keys. In this scenario, the attacker used a scheduled task to maintain access, which is a classic Persistence technique (T1053.005 Scheduled Task/Job: Scheduled Task). This tactic ensures the adversary can re-establish access even after a reboot or credential change, making it a correct classification.
C
Privilege Escalation
Why it fails: Privilege Escalation involves techniques to gain higher-level permissions, such as exploiting a vulnerability or abusing misconfigured services. The scenario describes a scheduled task for maintaining access and file encryption for disruption, neither of which necessarily involves elevating privileges. While scheduled tasks can sometimes be used for privilege escalation, the stated purpose here is persistence, not escalation. Therefore, this tactic does not fit the observed behaviors.
D
Defense Evasion
Why it fails: Defense Evasion covers techniques to avoid detection, such as obfuscation or disabling security tools. The scenario does not mention any attempt to evade defenses; the attacker used a scheduled task and encrypted files. While encryption might incidentally hinder analysis, the primary goal of encrypting files for disruption is Impact, not Defense Evasion. Thus, this tactic is not supported by the described behaviors.
E
Impact
Impact includes techniques that adversaries use to disrupt availability or compromise integrity, such as data destruction, encryption for ransom, or defacement. Encrypting files on a file share to disrupt operations is a direct Impact technique (T1486 Data Encrypted for Impact). This behavior aims to disrupt business operations, making Impact a correct classification for the second observed activity.

Question 3hardmultiple choice

You are analyzing a malware sample that communicates with a command-and-control (C2) server. The network traffic shows periodic HTTP GET requests to a domain that resolves to multiple IP addresses, and the User-Agent string is identical across all requests. Which of the following analytical techniques would best help you identify the infrastructure and potential attribution of the threat actor?

Trap 1: Reviewing the User-Agent string against known malware families.

While User-Agent strings can sometimes indicate malware families, they are easily spoofed and not reliable for attribution. The identical User-Agent across requests is a clue but does not map infrastructure. This technique alone would not provide the historical domain-to-IP relationships needed to identify the C2 infrastructure and potential actor.

Trap 2: Sandbox execution to observe the malware's behavior in a controlled…

Sandbox execution shows behavior but may not reveal historical DNS resolutions or infrastructure evolution. It is useful for dynamic behavior but does not provide the broader context of domain-to-IP mappings over time. The scenario already has network traffic, so sandboxing may not add the needed infrastructure insight for attribution.

Trap 3: Static malware analysis to extract embedded strings and…

Static analysis can reveal C2 domains and configuration, but it does not provide historical infrastructure mapping or attribution. The scenario already shows network traffic, so static analysis might be redundant. It also may not uncover the full set of IPs the domain has resolved to over time, which is key to understanding the infrastructure.

A
Reviewing the User-Agent string against known malware families.
Why it fails: While User-Agent strings can sometimes indicate malware families, they are easily spoofed and not reliable for attribution. The identical User-Agent across requests is a clue but does not map infrastructure. This technique alone would not provide the historical domain-to-IP relationships needed to identify the C2 infrastructure and potential actor.
B
Sandbox execution to observe the malware's behavior in a controlled environment.
Why it fails: Sandbox execution shows behavior but may not reveal historical DNS resolutions or infrastructure evolution. It is useful for dynamic behavior but does not provide the broader context of domain-to-IP mappings over time. The scenario already has network traffic, so sandboxing may not add the needed infrastructure insight for attribution.
C
Passive DNS analysis to map historical domain-to-IP resolutions.
Passive DNS analysis reveals historical mappings between the domain and IP addresses, helping identify infrastructure changes and potentially linking to other domains used by the same actor. This is crucial when the domain resolves to multiple IPs, as it can uncover patterns like fast flux or domain generation algorithms. It also aids attribution by correlating with known malicious infrastructure.
D
Static malware analysis to extract embedded strings and configuration.
Why it fails: Static analysis can reveal C2 domains and configuration, but it does not provide historical infrastructure mapping or attribution. The scenario already shows network traffic, so static analysis might be redundant. It also may not uncover the full set of IPs the domain has resolved to over time, which is key to understanding the infrastructure.

Question 4hardmultiple choice

An intelligence analyst is tasked with tailoring intelligence requirements for a merger and acquisition (M&A) scenario. Which methodology should be applied during the direction phase to identify threat actors specifically interested in compromising corporate transactions?

Trap 1: Network Forensic Packet Capture Analysis

Packet capture analysis is a technical investigative technique used post-compromise or during deep network troubleshooting.

Trap 2: Signature-Based Intrusion Detection Analysis

Signature-based detection is an operational mechanism for matching known malicious byte patterns in network traffic.

Trap 3: Vulnerability Scoring via CVSS v3.1 Base Metrics

CVSS scoring measures technical software flaws, not the intent or motivations of threat actors targeting business events.

A
Target-Centric Intelligence Analysis
Target-centric analysis focuses on a specific entity, event, or transaction (like an M&A), aligning collection requirements around actors targeting that specific asset.
B
Network Forensic Packet Capture Analysis
Why it fails: Packet capture analysis is a technical investigative technique used post-compromise or during deep network troubleshooting.
C
Signature-Based Intrusion Detection Analysis
Why it fails: Signature-based detection is an operational mechanism for matching known malicious byte patterns in network traffic.
D
Vulnerability Scoring via CVSS v3.1 Base Metrics
Why it fails: CVSS scoring measures technical software flaws, not the intent or motivations of threat actors targeting business events.

Question 5easymultiple choice

Which regulatory framework should a company consider when sharing threat intelligence that contains PII (Personally Identifiable Information) with international partners?

Trap 1: HIPAA

HIPAA governs protected health information held by US healthcare entities, so it does not address general PII shared internationally. It is tempting because it does regulate data privacy, but it would be the right framework only when the shared intelligence contains medical records handled by a covered entity.

Trap 2: SOX

SOX mandates financial reporting controls for publicly traded US companies, so it imposes no requirements on cross-border PII sharing. It tempts because it is a well-known compliance framework, but it would be relevant only when threat intelligence touches financial records or disclosure controls.

Trap 3: PCI-DSS

PCI-DSS is a contractual card-data security standard, not a privacy law governing PII transfers between countries. It tempts because it does impose data-handling rules, yet it applies only to organisations storing, processing or transmitting payment card data, not to general threat intelligence sharing.

A
GDPR
GDPR governs processing and cross-border transfer of personal data, so sharing threat intelligence containing PII with international partners triggers its lawful-basis, transfer-mechanism and safeguards requirements. It directly addresses the international PII-sharing constraint in the stem.
B
HIPAA
Why it fails: HIPAA governs protected health information held by US healthcare entities, so it does not address general PII shared internationally. It is tempting because it does regulate data privacy, but it would be the right framework only when the shared intelligence contains medical records handled by a covered entity.
C
SOX

It tempts because it does impose data-handling rules, yet it applies only to organisations storing, processing or transmitting payment card data, not to general threat intelligence sharing.

Question 6mediummultiple choice

You are reviewing network traffic logs for potential C2 (Command and Control) beaconing. You decide to use a rolling average to smooth out the data. Why is this statistical technique useful in this scenario?

Trap 1: It increases the absolute volume of the data collected.

A rolling average reduces noise by aggregating values across a window; it does not increase the volume of data collected, and doing so would obscure rather than reveal beaconing patterns. Increasing collection volume would be relevant when raw telemetry is insufficient, but smoothing works on existing logs to expose periodic C2 intervals.

Trap 2: It eliminates the need for further traffic inspection.

A rolling average smooths short-term fluctuations so underlying periodic beaconing patterns become visible; it does not replace traffic inspection, which remains necessary to confirm malicious C2 activity. Eliminating further inspection would be tempting when reducing analyst workload, but the technique only aids pattern detection, it cannot validate or classify traffic.

Trap 3: It encrypts the log data for safer analysis.

A rolling average is a statistical smoothing method applied to numeric time-series values; it performs no cryptographic operation on log data. Encryption would be the correct choice when protecting log confidentiality at rest or in transit, but here the goal is revealing periodic beaconing intervals, which smoothing achieves without altering data security.

A
It helps filter out random 'noise' to highlight consistent temporal patterns.
Beaconing generates periodic traffic buried within noisy logs. A rolling average smooths short-term fluctuations, suppressing random spikes so consistent temporal patterns, such as regular fixed intervals, become visible. This reveals the rhythmic check-in behaviour characteristic of command-and-control channels.
B
It increases the absolute volume of the data collected.
Why it fails: A rolling average reduces noise by aggregating values across a window; it does not increase the volume of data collected, and doing so would obscure rather than reveal beaconing patterns. Increasing collection volume would be relevant when raw telemetry is insufficient, but smoothing works on existing logs to expose periodic C2 intervals.
C

Question 7mediummultiple choice

You are analyzing an intrusion set and need to assess how consistently a specific adversary group has targeted your industry over the past 18 months. You have a feed of 4,200 indicators, but 3,100 of them are domain names that resolve to shared CDN infrastructure used by thousands of legitimate sites. Which structured analytic technique is MOST appropriate to reduce this noise before you draw conclusions about targeting patterns?

Trap 1: Convert the domain indicators to IP addresses using current passive…

Resolving domains to current IPs introduces resolution drift and does not separate shared CDN infrastructure from adversary-owned infrastructure. The resulting counts would still be dominated by CDN-hosted domains and could create false pivots to unrelated victims. This technique adds noise rather than reducing it for a targeting-consistency assessment.

Trap 2: Increase the confidence rating on all indicators from the feed…

Commercial provenance does not make an indicator discriminative. Raising confidence uniformly would amplify the very CDN noise you are trying to remove and could bias your targeting assessment toward false consistency. Confidence should be assigned per indicator based on corroboration and specificity, not blanket-upgraded because of the feed vendor.

Trap 3: Run all 4,200 indicators through a sandbox and retain only those…

Sandboxing domain names does not resolve the core problem: shared CDN domains may be benign when resolved now but were abused during the campaign window. Dynamic analysis is also slow and produces verdicts about current content, not historical targeting intent. It would still leave thousands of CDN indicators in the set, so it fails to reduce noise for this pattern-of-life question.

A
Convert the domain indicators to IP addresses using current passive DNS and re-run the frequency count.
Why it fails: Resolving domains to current IPs introduces resolution drift and does not separate shared CDN infrastructure from adversary-owned infrastructure. The resulting counts would still be dominated by CDN-hosted domains and could create false pivots to unrelated victims. This technique adds noise rather than reducing it for a targeting-consistency assessment.
B
Apply pivoting on the shared infrastructure to cluster indicators by hosting ASN, then filter clusters that also contain non-targeted victim domains.
Pivoting on hosting infrastructure lets you group indicators that share an ASN or netblock, revealing which clusters are adversary-specific versus commodity CDN noise. By filtering clusters that also contain non-targeted victim domains, you remove indicators that lack discriminative value for this targeting question. This preserves the analytic integrity of the remaining data set before you assess consistency of targeting.
C
Increase the confidence rating on all indicators from the feed because the feed is a commercial source.
Why it fails: Commercial provenance does not make an indicator discriminative. Raising confidence uniformly would amplify the very CDN noise you are trying to remove and could bias your targeting assessment toward false consistency. Confidence should be assigned per indicator based on corroboration and specificity, not blanket-upgraded because of the feed vendor.
D
Run all 4,200 indicators through a sandbox and retain only those that trigger a malicious verdict.
Why it fails: Sandboxing domain names does not resolve the core problem: shared CDN domains may be benign when resolved now but were abused during the campaign window. Dynamic analysis is also slow and produces verdicts about current content, not historical targeting intent. It would still leave thousands of CDN indicators in the set, so it fails to reduce noise for this pattern-of-life question.

Question 8mediummultiple choice

A global manufacturing company is establishing a new CTI program. The CISO wants to ensure that intelligence production remains focused on the organization's most critical business assets and that resources are allocated efficiently. Which of the following should the CTI manager produce FIRST to define the specific intelligence needs that support strategic decision-making?

Trap 1: Stakeholder contact list

A stakeholder contact list supports communication but does not define intelligence requirements. It is a supporting document, not a driver of collection or analysis. While stakeholder engagement is important, the scenario specifically asks for defining intelligence needs to support strategic decision-making, which requires PIRs, not a contact list.

Trap 2: Threat Intelligence Platform (TIP) deployment

A TIP is a technical tool for aggregating and managing threat data, not a requirements-definition artifact. Deploying a TIP before establishing PIRs would automate collection without strategic focus, likely resulting in data overload and misalignment with business goals. The CISO's request is about defining needs, not selecting technology.

Trap 3: Intelligence Collection Plan

An intelligence collection plan outlines how data will be gathered to satisfy requirements, but it is developed after requirements are defined. Without PIRs, the collection plan lacks direction and may waste resources on irrelevant data. The scenario emphasizes defining needs first, so a collection plan is premature.

A
Stakeholder contact list
Why it fails: A stakeholder contact list supports communication but does not define intelligence requirements. It is a supporting document, not a driver of collection or analysis. While stakeholder engagement is important, the scenario specifically asks for defining intelligence needs to support strategic decision-making, which requires PIRs, not a contact list.
B
Priority Intelligence Requirements (PIRs)
PIRs are the primary output of the direction phase and directly articulate the intelligence needs tied to strategic decision-making. They ensure collection and analysis efforts are aligned with the organization's critical assets and business objectives, enabling efficient resource allocation. In this scenario, the CISO's focus on critical assets and strategic decisions makes PIRs the essential first step.
C
Threat Intelligence Platform (TIP) deployment

Question 9hardmultiple choice

A threat intelligence analyst is integrating a new external feed into the organization's SIEM. The feed provides indicators with varying confidence levels. The analyst must ensure that only high-confidence indicators trigger automated alerts to reduce false positives. Which component of the intelligence lifecycle is most directly involved in this filtering process?

Trap 1: Dissemination

Dissemination is the distribution of finished intelligence to consumers. It occurs after analysis and does not involve filtering or confidence assessment. The scenario describes setting criteria for alerts, which is part of analysis, not dissemination. Dissemination ensures the right people receive the intelligence but does not decide which indicators are high-confidence.

Trap 2: Collection

Collection involves acquiring raw data from various sources. While it is the first step, it does not include filtering or confidence assessment. The scenario focuses on processing and evaluating indicators after collection. Collection ensures data is gathered but does not determine which indicators are high-confidence for alerting.

Trap 3: Processing

Processing converts raw data into a format suitable for analysis, such as normalizing fields or parsing. It does not assess confidence or relevance. The filtering of high-confidence indicators occurs after processing, during analysis, where the data is evaluated against organizational context and requirements.

A
Dissemination
Why it fails: Dissemination is the distribution of finished intelligence to consumers. It occurs after analysis and does not involve filtering or confidence assessment. The scenario describes setting criteria for alerts, which is part of analysis, not dissemination.

Why it fails: Collection involves acquiring raw data from various sources. While it is the first step, it does not include filtering or confidence assessment. The scenario focuses on processing and evaluating indicators after collection. Collection ensures data is gathered but does not determine which indicators are high-confidence for alerting.
C
Analysis
Analysis is where raw intelligence is evaluated for relevance, reliability, and confidence. In this scenario, the analyst applies confidence thresholds to determine which indicators should trigger alerts. This step involves contextualizing the data and making judgments about its trustworthiness, directly influencing automated alerting rules.
D
Processing
Why it fails: Processing converts raw data into a format suitable for analysis, such as normalizing fields or parsing. It does not assess confidence or relevance. The filtering of high-confidence indicators occurs after processing, during analysis, where the data is evaluated against organizational context and requirements.

Question 10mediummultiple choice

You are a CTI analyst at a multinational corporation. You have produced a strategic intelligence report assessing the long-term threat posed by a nation-state actor targeting your industry. The report includes sensitive details about your organization's defensive posture. You need to share it with your subsidiary in a foreign country. Which TLP marking should you apply to ensure the information is shared appropriately while protecting your organization's interests?

Trap 1: TLP:CLEAR

TLP:CLEAR (formerly TLP:WHITE) allows unrestricted sharing, which is completely unsuitable for sensitive intelligence about defensive measures. Using this marking would risk exposing your organization's vulnerabilities and could aid adversaries. It is meant for public information only.

Trap 2: TLP:RED

TLP:RED is for information that should not be shared beyond specific named recipients. While it offers strong protection, it may be too restrictive for sharing with a subsidiary, as it typically requires individual handling and may hinder the subsidiary's ability to act on the intelligence. It is best reserved for the most sensitive information.

Trap 3: TLP:GREEN

TLP:GREEN permits sharing with the broader community, which is too permissive for sensitive details about your organization's defensive posture. This could lead to unintended disclosure and potential targeting by adversaries. It is not appropriate for information that should be restricted to the organization and its close partners.

C
TLP:AMBER
TLP:AMBER allows sharing within the organization and with its clients or subsidiaries as needed. It provides a balance between protection and necessary dissemination, making it suitable for sensitive information that needs to be shared with a foreign subsidiary while still limiting further distribution. This marking aligns with the need to protect defensive details while enabling action.
D
TLP:GREEN
Why it fails: TLP:GREEN permits sharing with the broader community, which is too permissive for sensitive details about your organization's defensive posture. This could lead to unintended disclosure and potential targeting by adversaries. It is not appropriate for information that should be restricted to the organization and its close partners.

Question 11hardmultiple choice

A threat intelligence analyst is studying an advanced persistent threat (APT) group that has been observed using a novel technique to maintain persistence. The group modifies the Windows Registry to add a malicious DLL to the AppInit_DLLs key, which loads the DLL into every process that loads User32.dll. Which MITRE ATT&CK technique is this an example of?

Trap 1: Registry Run Keys / Startup Folder

Registry Run Keys / Startup Folder is a persistence technique where adversaries add entries to registry run keys or startup folders to execute programs at user logon. The scenario describes modifying AppInit_DLLs, which is a different registry key that injects a DLL into processes. While both are registry-based, the specific mechanism and behavior differ, so this is not the correct technique.

Trap 2: DLL Search Order Hijacking

DLL Search Order Hijacking is a technique where adversaries place a malicious DLL in a location that is searched before the legitimate DLL, causing the system to load the malicious one. The scenario does not involve search order manipulation; instead, it uses the AppInit_DLLs registry key to load a DLL. Therefore, this technique does not apply here.

Trap 3: Image File Execution Options Injection

Image File Execution Options Injection is a persistence technique where adversaries modify the IFEO registry key to launch a malicious executable when a legitimate program is started. The scenario describes loading a DLL via AppInit_DLLs, not IFEO. Although both use registry modifications, the specific keys and behaviors are distinct, so this option is incorrect.

A

D
AppInit DLLs
AppInit DLLs is a specific MITRE ATT&CK technique under Persistence and Privilege Escalation. It involves modifying the AppInit_DLLs registry key to load a malicious DLL into every process that loads User32.dll, providing persistence and often privilege escalation. The scenario exactly matches this technique, making it the correct answer.

Question 12mediummultiple choice

A threat intelligence analyst is assessing an adversary's use of the 'Kill Chain' model. The analyst notes that the adversary has successfully delivered a malicious payload to the target and is now establishing a command-and-control (C2) channel. Which phase of the Cyber Kill Chain does this activity represent?

Trap 1: Installation

Installation is when the adversary installs malware on the victim's system. This typically happens before C2 establishment. The scenario says the adversary is now establishing a C2 channel, indicating installation has already occurred. Installation is not the phase for C2.

Trap 2: Actions on Objectives

Actions on Objectives is the final phase where the adversary achieves their goals, such as data exfiltration or destruction. Establishing C2 is a prerequisite for actions on objectives, not the phase itself. The scenario describes C2 establishment, which precedes actions on objectives.

Trap 3: Exploitation

Exploitation occurs when the adversary takes advantage of a vulnerability to execute code. While exploitation may have happened before C2, the scenario specifically describes establishing C2, which is a later phase. Exploitation is not the phase for setting up communication channels.

A
Command and Control
The Command and Control phase is when the adversary establishes a communication channel with the compromised system. After delivery and exploitation, the attacker needs to control the malware. The scenario states the adversary is establishing a C2 channel, which directly matches this phase.
B
Installation
Why it fails: Installation is when the adversary installs malware on the victim's system. This typically happens before C2 establishment. The scenario says the adversary is now establishing a C2 channel, indicating installation has already occurred. Installation is not the phase for C2.
C
Actions on Objectives
Why it fails: Actions on Objectives is the final phase where the adversary achieves their goals, such as data exfiltration or destruction. Establishing C2 is a prerequisite for actions on objectives, not the phase itself. The scenario describes C2 establishment, which precedes actions on objectives.
D
