Defense Evasion covers techniques used to avoid detection throughout the lifecycle.
Why this answer
Process Hollowing is a form of Defense Evasion, as it allows malicious code to hide inside a legitimate process.
A security analyst is using the Diamond Model to document an incident. The analyst notes that the adversary used a specific Command and Control (C2) server IP address. In the context of the Diamond Model, where does this IP address belong?
Infrastructure captures the C2 nodes and tools used to facilitate the attack.

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?
Target-centric analysis focuses on a specific entity, event, or transaction (like an M&A), aligning collection requirements around actors targeting that specific asset.
Why this answer
Target-centric intelligence analysis focuses specifically on the assets, events, or transactions of interest (such as an M&A deal) and maps out all threat actors known to target those specific equities.

A newly formed CTI team is conducting stakeholder interviews to establish intelligence requirements. The Chief Risk Officer (CRO) expresses concern over ransomware supply chain disruptions. How should the intelligence analyst translate this concern into a formal intelligence requirement?
This directly addresses the CRO's concern by focusing collection and analysis on supply chain threat actors, TTPs, and campaigns.
Why this answer
Translating executive concerns into formal requirements involves formulating specific, answerable questions regarding supply chain vulnerabilities and active ransomware campaigns targeting third-party vendors.
During the planning phase of building a CTI team, the program manager needs to define the scope of intelligence operations. Which category of intelligence focuses specifically on technical indicators such as file hashes, IP addresses, and domain names?

You are ingesting threat data into a TIP and notice that indicators lack 'TLP' (Traffic Light Protocol) markings. What is the standard industry procedure?
Standard practice is to default to the most restrictive level.
Why this answer
When TLP is missing, the default safest practice is to assume TLP:RED or the most restrictive category to prevent unauthorized disclosure.
You are troubleshooting a synchronization issue between two threat intelligence platforms. One platform is configured for TAXII 2.1 and the other is receiving the data but failing to parse the STIX 2.1 bundle. Which diagnostic step is most appropriate?
Parsing errors are almost always due to non-compliant JSON structures.
You are analyzing an intelligence report provided in STIX 2.1 format. You find an 'Identity' object being used to attribute the campaign. What is the most common use of the 'Identity' object in this context?
The Identity object describes a person or organization involved in the activity.
