Operationalizing Threat Intelligence

By: Kyle Wilhoit, Joseph Opacki

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.

Reverse engineering

If the goal of your organization is to fully understand the complete heuristic functionality of a malware payload, then performing static and dynamic analysis on the file will not give you this information. Static analysis tools will provide you with insightful artifacts and some IOCs that can be used to identify, collect, and even assist with determining a file. Dynamic analysis will provide you with information about what happens to the operating system at the beginning of the file's execution, not the full execution behavior of the file. This is where reverse engineering comes into play.

As we mentioned earlier, reverse engineering utilizes a combination of disassembling, debugging, and decompilation to examine the full heuristic functionality of a binary file. It does this by reviewing the interpreted assembly that is produced by the contents of the file. Reverse engineering is a technically complex skill set and has a range of books written about it...
