Practical Threat Intelligence and Data-Driven Threat Hunting

By: Valentina Costa-Gazcón

Overview of this book

Threat hunting (TH) provides cybersecurity analysts and enterprises with the opportunity to proactively defend themselves by getting ahead of threats before they can cause major damage to their business. This book is not only an introduction for those who don’t know much about the cyber threat intelligence (CTI) and TH world, but also a guide for those with more advanced knowledge of other cybersecurity fields who are looking to implement a TH program from scratch. You will start by exploring what threat intelligence is and how it can be used to detect and prevent cyber threats. As you progress, you’ll learn how to collect data, along with understanding it by developing data models. The book will also show you how to set up an environment for TH using open source tools. Later, you will focus on how to plan a hunt with practical examples, before going on to explore the MITRE ATT&CK framework. By the end of this book, you’ll have the skills you need to be able to carry out effective hunts in your own environment.

Mapping with ATT&CK

In the following exercise, we are going to use a paper that was presented at Virus Bulletin 2018: Inside Formbook Infostealer by the malware researcher Gabriela Nicolao: https://www.virusbulletin.com/uploads/pdf/magazine/2018/VB2018-Nicolao.pdf.

Formbook is an infostealer that has been around since at least 2016 and has been advertised in hacking forums by the user ng-Coder. Its code is written in assembler inline instruction within C code (ASM C). It has been used in several campaigns that have impacted both the US and South Korea, and is also related to some threat actors, such as SWEED and Cobalt.

In this section, we are going to learn how to map Formbook's infostealer behavior with ATT&CK.
