Develop actionable strategies to proactively hunt advanced persistent threats and detect zero-days using CTI and behavior-based detection techniques Key Features Intelligence-led threat hunting framework for detecting APTs and zero-day attacks at scale Hands-on detection of stealthy adversaries using behavioral analytics and machine learning Real-world hunting workflows across cloud, hybrid, and enterprise environments Book Description Modern adversaries rely on stealth, living-off-the-land techniques, and zero-day exploitation to evade traditional security controls. This practical guide shows experienced defenders how to move beyond reactive alerts and build a proactive threat hunting capability driven by cyber threat intelligence. Written for seasoned cybersecurity professionals, the book demonstrates how to formulate CTI-driven hunt hypotheses and detect advanced persistent threats by analyzing adversary behavior across the Cyber Kill Chain. You’ll learn how to track APT infrastructure, map attacker TTPs using the MITRE ATT&CK framework, and identify post-exploitation activity that signals successful compromise. Through hands-on exercises, you’ll apply behavioral analytics, detection engineering, and machine learning–based anomaly detection to uncover what signature-based tools miss. Coverage includes threat hunting in cloud, hybrid, and ICS/OT environments, with real-world techniques for lateral movement, persistence, privilege escalation, and data exfiltration. By the end of this book, you’ll be equipped to run intelligence-led threat hunts, detect advanced threats earlier, and operationalize CTI as a core part of your defensive strategy. What you will learn Build CTI-driven hypotheses for proactive threat hunting Detect APT behavior across the Cyber Kill Chain Identify zero-day activity using behavioral analytics Apply MITRE ATT&CK to map adversary TTPs Use machine learning for anomaly-based detection Hunt post-exploitation activity and lateral movement Investigate threats in cloud and hybrid environments Design a scalable, resilient threat hunting program Who this book is for This book is tailored for experienced, mid-to-senior level cybersecurity professionals operating in roles focused on proactive defense. The audience includes cyber threat hunters, cybersecurity analysts, cyber intelligence analysts, and incident responders. These profiles are looking to bridge the gap between intelligence production and its actionable application in live hunting operations, and this book will help them to achieve this.
