Are you having trouble creating your intelligence requirements? Fear not—this excellent YouTube playlist will help you get started! It covers how to use Intel471’s Cyber Underground General Intelligence Handbook (CU-GIRH) to take general intelligence and make it unique to your organization. This includes creating Priority Intelligence Requirements, assessing the feasibility of these requirements, and building a Collection Plan to ensure you can fulfill them.
👉 A great resource I recommend every cyber threat intelligence analyst tries out!

You Should Know:
1. Creating Priority Intelligence Requirements (PIR):
- Use the following template to define PIRs:
PIR Template:</li> <li>Objective: [What is the goal?]</li> <li>Stakeholder: [Who needs this intelligence?]</li> <li>Intelligence Question: [What specific question needs answering?]</li> <li>Timeframe: [When is this intelligence needed?]</li> <li>Priority: [High/Medium/Low]
- Example:
</li> <li>Objective: Identify potential ransomware threats targeting the finance sector.</li> <li>Stakeholder: CISO</li> <li>Intelligence Question: What are the latest ransomware groups targeting financial institutions?</li> <li>Timeframe: Within the next 7 days.</li> <li>Priority: High
2. Assessing Feasibility:
- Use the following command to gather threat intelligence data from open-source tools like `MISP` (Malware Information Sharing Platform):
misp-cli search --type threat-actor --tags ransomware
- This command searches for ransomware-related threat actors in your MISP instance.
3. Building a Collection Plan:
- Use `Python` to automate data collection from threat feeds:
import requests</li> </ul> def fetch_threat_feed(url): response = requests.get(url) if response.status_code == 200: return response.json() else: return None feed_url = "https://example.com/threat-feed" threat_data = fetch_threat_feed(feed_url) print(threat_data)
4. Linux Command for Threat Hunting:
- Use `grep` to search for suspicious IPs in log files:
grep "192.168.1.100" /var/log/auth.log
- This command searches for a specific IP address in the authentication log.
5. Windows Command for Incident Response:
- Use `PowerShell` to list all running processes:
Get-Process | Format-Table Name, Id, CPU
- This command helps identify suspicious processes consuming high CPU.
What Undercode Say:
Creating actionable intelligence requirements is a critical skill for cyber threat analysts. By leveraging tools like Intel471’s CU-GIRH, you can streamline the process of defining PIRs, assessing feasibility, and building collection plans. Automating data collection with scripts and using commands like `grep` and `Get-Process` can significantly enhance your threat-hunting capabilities. Always ensure your intelligence requirements align with organizational goals and are feasible given available resources.
