- This repository contains instructions and resources for an intelligence analysis challenge
 - It was created to test cyber threat intelligence (CTI) analysts looking to practice performing proactive and reactive CTI tasks.
 - CTI analysts need to review them and perform tasks to complete and fulfil their demo client's priority intelligence requirements (PIRs) and requests for intelligence (RFIs).
 
- 
Analysts can decide whether they want to begin with the proactive CTI challenge or the reactive CTI challenge
 - 
Proactive CTI Challenge:
- To begin the proactive CTI challenge, analysts need to review the 
Proactive CTI Diagram, theDemo Stakeholders, and theIntelligence Sources. - Analysts then need to follow the steps laid out in the diagram to think about stakeholder PIRs and then review the intelligence sources.
 - CTI Incident Reports then need to be written by the analysts to meet the PIRs of their chosen stakeholder.
 - Analysts can use the 
CTI Incident Report Templateprovided. 
 - To begin the proactive CTI challenge, analysts need to review the 
 - 
Reactive CTI Challenge:
- To begin the reactive CTI challenge, analysts need to review the 
Reactive CTI Diagram, theDemo Stakeholders, and theDemon Incident Artifacts. - Analysts then need to follow the steps laid out in the diagram to think about the stakeholder's RFIs and then review the incident artifacts.
 - A reponse to the RFI then needs to be written by the analysts to fulfil the RFI made by their chosen stakeholder.
 - While reviewing the artifacts, analysts need to provide context about the threat, such as the level of danger it poses to the target organisations.
 - It is also advisable to provide potential Courses of Action (CoAs) to support requesting stakeholders while they are investigating incidents.
 - Analysts can use the 
RFI Response Templateprovided. 
 - To begin the reactive CTI challenge, analysts need to review the 
 - 
Additional Notes:
- The way your reports are written may also depend on the type of organisation you are a CTI analyst for.
 - Analysts who work for a vendor with many clients may frame their reports differently than in-house CTI teams that work full time for the same single organisation.
 - For this challenge, it is recommended to write the reports in the format you are used to or want to get better at.

|---|---|---|
| Proactive CTI Diagram | A diagram explaining the process involved in taking intelligence sources and satisfying stakeholder priority intelligence requirements (PIRs). | Use this as a guide to understand the order of tasks you need to perform in a real-world scenario when working in a CTI team. | 
| Reactive CTI Diagram | A diagram explaing the process involved in taking incident artifacts and satisfying stakeholder requests for intelligence (RFIs). | Use this as a guide to understand the order of tasks you need to perform in a real-world scenario when working in a CTI team. | 
| Demo Stakeholders | A list of fictional organisations that analysts are to use to practice fulfilling their PIRs using the Intelligence Sources and their RFIs using the Demo Incident Artifacts provided below. | 
Imagine that these organisations are your clients or the company that work for. Your job as an analyst is to protect these entities and help them defend from emerging threats. | 
| Demo Intelligence Sources | A collection of threat reports and articles that need to be checked for relevence for their chosen organisation(s). | Analysts need to scan through, understand, and extract the most important information from the threat reports and articles to provide actionable threat intelligence. Follow the Proactive CTI Diagram steps. | 
| Demo Incident Artifacts | A collection of Indicators and Compromise (IOCs) taken from real attacks but have been provided to simulate an RFI that a real-world stakeholder (such as a SOC or DFIR team) provided the CTI team for additional context and recommendations. | Analysts need to triage, research, and assess the IOCs, artifacts, and incident details and provide a response to the stakeholder that support their actions while handling the incident. Follow the Reactive CTI Diagram steps. | 
| CTI Incident Report Template | A basic report template to help write CTI Incident Reports. | Use the template as a guide to help perform proactive CTI activities. | 
| RFI Response Template | A basic report template to help write RFI Response reports. | Use the template as a guide to help perform reactive CTI activities. |
