Mastering Cyber Intelligence

By: Jean Nestor M. Dahj

Overview of this book

The sophistication of cyber threats, such as ransomware, advanced phishing campaigns, zero-day vulnerability attacks, and advanced persistent threats (APTs), is pushing organizations and individuals to change strategies for reliable system protection. Cyber Threat Intelligence converts threat information into evidence-based intelligence that uncovers adversaries' intents, motives, and capabilities for effective defense against all kinds of threats. This book thoroughly covers the concepts and practices required to develop and drive threat intelligence programs, detailing the tasks involved in each step of the CTI lifecycle. You'll be able to plan a threat intelligence program by understanding and collecting the requirements, setting up the team, and exploring the intelligence frameworks. You'll also learn how and from where to collect intelligence data for your program, considering your organization level. With the help of practical examples, this book will help you get to grips with threat data processing and analysis. And finally, you'll be well-versed with writing tactical, technical, and strategic intelligence reports and sharing them with the community. By the end of this book, you'll have acquired the knowledge and skills required to drive threat intelligence operations from planning to dissemination phases, protect your organization, and help in critical defense decisions.

Creating and sharing IOCs

Let's consider the intrusion analysis performed in Chapter 10, Threat Modeling and Analysis - Practical Use Cases, with the simplified kill chain discovery action shown in the following figure. Some of the other indicators extracted during the analysis included the executable.1640.exe hash value, 12cf6583f5a9171a1d621ae02b4eb626, and the resoh.ru domain:

Sharing threat intelligence makes the defense against cyber threats more effective. After a successful analysis, a CTI analyst should select the correct format and platform to disseminate the results internally and externally. This section looks at IOC sharing and the use of YARA to detect malicious traffic.

Use case one – developing IOCs using YARA

YARA is common for malware detection and traffic monitoring. Its structure was introduced in Chapter 14, Threat Intelligence Reporting...
