Incident Response with Threat Intelligence

By: Roberto Martinez

Overview of this book

With constantly evolving cyber threats, developing a cybersecurity incident response capability to identify and contain threats is indispensable for any organization regardless of its size. This book covers theoretical concepts and a variety of real-life scenarios that will help you to apply these concepts within your organization. Starting with the basics of incident response, the book introduces you to professional practices and advanced concepts for integrating threat hunting and threat intelligence procedures in the identification, contention, and eradication stages of the incident response cycle. As you progress through the chapters, you'll cover the different aspects of developing an incident response program. You'll learn the implementation and use of platforms such as TheHive and ELK and tools for evidence collection such as Velociraptor and KAPE before getting to grips with the integration of frameworks such as Cyber Kill Chain and MITRE ATT&CK for analysis and investigation. You'll also explore methodologies and tools for cyber threat hunting with Sigma and YARA rules. By the end of this book, you'll have learned everything you need to respond to cybersecurity incidents using threat intelligence.

Analyzing and identifying patterns in files

An essential part of creating YARA rules is the identification of patterns in the files we want to search. There are several tools that can help us with this; in this case, we will use a tool known as PeStudio.

Downloading PeStudio

PeStudio is a tool to analyze files with a portable executable (PE) structure, for instance, Windows files with the .exe, .dll, and .bin extensions. You can find more details about the PE structure at https://docs.microsoft.com/en-us/windows/win32/debug/pe-format.

To download and install PeStudio, follow these steps:

  1. Download the free version directly from https://www.winitor.com/download.
  2. From the Downloads directory, right-click on the pestudio.zip file and select Extract All….
  3. Click on the Browse… button and navigate to the C:\Users\Investigator\Workspace\Tools directory.
