Overview of this book

We’re living in an era where cyber threat intelligence is becoming more important. Cyber threat intelligence routinely informs tactical and strategic decision-making throughout organizational operations. However, finding the right resources on the fundamentals of operationalizing a threat intelligence function can be challenging, and that’s where this book helps. In Operationalizing Threat Intelligence, you’ll explore cyber threat intelligence in five fundamental areas: defining threat intelligence, developing threat intelligence, collecting threat intelligence, enrichment and analysis, and finally production of threat intelligence. You’ll start by finding out what threat intelligence is and where it can be applied. Next, you’ll discover techniques for performing cyber threat intelligence collection and analysis using open source tools. The book also examines commonly used frameworks and policies as well as fundamental operational security concepts. Later, you’ll focus on enriching and analyzing threat intelligence through pivoting and threat hunting. Finally, you’ll examine detailed mechanisms for the production of intelligence. By the end of this book, you’ll be equipped with the right tools and understand what it takes to operationalize your own threat intelligence function, from collection to production.

Similarity analysis tools

Now that we have examined similarity grouping from a top-level standpoint, let's examine the different toolsets that can be used to perform similarity grouping practically. First, let's examine the ever-popular tool known as YARA.

YARA

When analyzing malware, researchers will often identify unique patterns and strings within the malware that helps them identify and group by the malware family, threat group, or campaign that those samples belong to or relate to. The researcher will commonly create a YARA rule from several samples of the same malware family to help identify additional malware samples associated with the same campaign, actor group, or malware family.

YARA has several use cases, but we'll focus on the three primary use cases for any threat intelligence professional:

  • Identify and classify malware
  • Find new and related samples based on family-specific patterns
  • Identify malware samples on compromised devices...
