دانلود کتاب یافتن بیکن ها در تاریکی – راهنمای اطلاعات تهدیدات سایبری

On October 29, 2015, I was on a plane, embarking on a thrilling journey to the Middle East region as a threat analyst. My mission was to investigate a breach at a government agency that handled sensitive operations. Despite my limited English proficiency and the stress of the unknown, I was excited for the adventure ahead. Upon arrival, I discovered that the intrusion in question was the result of a well-executed cyber-attack. The attackers had sent out a weaponized document that, after execution, delivered a remote access trojan. This document had been unwittingly opened by an employee; a classic scenario. The attackers quickly gained access to the network, which they quietly explored to gather information and map out the architecture, patiently monitoring the organization and learning the habits of its employees until they found the right moment to strike. They gained access to a file server, from which they were able to collect and compile sensitive, classified documents before exfiltrating the data via a compromised email account. This espionage operation was carried out by a sophisticated threat actor with political interest in the region, who managed to hide inside the network for months, biding their time and gaining intel. Since that day, I fell in love with the adrenaline of investigation, the process of uncovering the truth, and the thrill of threat intelligence research. It was a turning point in my career. I’ve never looked back. Threat intelligence is one of the most exciting and challenging topics in hacking and computer science. It is also a difficult one to understand as it requires knowledge of a lot of different concepts, experiences, and practices. You have in your hand a condensed threat intelligence guide extracted from my own experiences. Over the course of my career, I have encountered and analyzed numerous high-profile cyberattacks, including those discussed in this book, perpetrated by nation-state actors and cybercriminals. Throughout these investigations, I worked closely with law enforcement agencies and gained a deep understanding of the tactics, techniques, and procedures used by threat actors. As someone who has been working in the field for over a decade, I have been witness to the rapid evolution of this topic and its expanding significance in today’s world, where attacks like Shamoon, Wannacry, and NotPetya gain international attention and can cause billions of dollars of damage. First-hand, I have seen the impact it has on individuals, organizations, and even countries. This book is a continuation of my popular cybersecurity infographics series https://bit.ly/SecBreakInfo, providing a unique and accessible approach to learning about practical concepts used in the fields of threat intelligence, incident response, and malware analysis. My goal is to provide a digestible and engaging learning experience for readers of all levels, including students, professionals, and researchers. I designed this book as a guide to understanding the key concepts and practical elements of threat intelligence. It is intended to serve as both a starting point for learning and a reference resource for professionals. I hope that this book will be a valuable asset to anyone interested in these topics and will inspire readers to continue learning and contributing to ongoing research and discussions.
