Threat Hunter: Hands-On Threat Hunting & Blue Team Guide

Description

Threat Hunter — The Complete Guide to Threat Hunting, Detection Engineering, MITRE ATT&CK, Incident Investigation, Threat Intelligence, and Modern SOC Operations

By Codelivly · First Edition · 385 pages · 108 chapters · 12 parts · 8 appendices

Stop waiting for alerts. Start hunting.

For two decades, cyber defense has leaned on a reactive model: deploy tools, wait for something to fire, and respond. Modern adversaries have made that model obsolete. They live off the land, blend into legitimate activity, disable logging, and move patiently through networks — exactly the behavior that signature-based alerting is worst at catching. Threat Hunter is the complete, hands-on answer: a single reference that teaches you to proactively find intrusions that slipped past every control, and to turn what you learn into durable, automated detection.

This is not abstract theory, and it’s not a scattering of one-off tricks. It’s a structured, repeatable methodology combined with concrete, platform-specific craft — organized around the MITRE ATT&CK framework and grounded in the real telemetry defenders work with every day. Every chapter is built to be used, not just read.

Who this book is for

• SOC analysts ready to move beyond alert triage into proactive, hypothesis-driven hunting
• Aspiring and practicing threat hunters who want a complete methodology, not fragments
• Detection engineers building, testing, tuning, and maintaining detections as code
• Incident responders who need stronger hunting and scoping skills
• Blue teamers and security engineers responsible for visibility, logging, and coverage
• Students and career changers seeking a rigorous, hands-on path into a high-demand specialty
• Team leads and managers who need to understand coverage, metrics, and program value

A working familiarity with operating systems, networking, and basic security concepts helps, but the book builds from foundations so motivated newcomers can grow into it.

What’s inside — the complete breakdown

Part I — Threat Hunting Foundations (12 chapters). The mindset, models, and vocabulary every hunt depends on: what threat hunting is; how it differs from detection engineering and incident response; the hunting lifecycle; hypothesis-, intelligence-, and data-driven hunting; a full MITRE ATT&CK overview; the Cyber Kill Chain; the Diamond Model of Intrusion Analysis; the Pyramid of Pain; and a career roadmap for the threat hunter.

Part II — Enterprise Visibility (11 chapters). The data every hunt is built on: Windows logging, Linux logging, Sysmon, PowerShell logging, authentication logs, DNS, firewall, proxy, and VPN logs, cloud logs, and endpoint telemetry — including what each source can and cannot tell you.

Part III — Threat Intelligence (9 chapters). Turning intelligence into outcomes: indicators of compromise (IOCs), indicators of attack (IOAs), threat actors and APT groups, tactics/techniques/procedures (TTPs), ATT&CK mapping, intelligence sources and validation, and operationalizing intelligence into hunts and detections.

Part IV — Detection Engineering (9 chapters). Building detections that last: the detection lifecycle, detection-as-code, writing Sigma rules, writing YARA rules, log parsing and normalization, detection tuning, reducing false positives, measuring detection coverage, and testing and validation.

Part V — MITRE ATT&CK Deep Dive (12 chapters). A tactic-by-tactic detection and hunting playbook covering every ATT&CK tactic: Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, Lateral Movement, Collection, Command and Control, Exfiltration, and Impact.

Part VI — Windows Threat Hunting (9 chapters). Hunting PowerShell abuse, the registry, scheduled tasks, Windows services, startup and autostart locations, Windows event logs, Sysmon events, lateral-movement indicators, and Windows timeline analysis.

Part VII — Linux Threat Hunting (9 chapters). Hunting SSH activity, cron and scheduled jobs, systemd abuse, Linux authentication, Linux processes, Linux persistence, bash history and shell activity, Linux system logs, and network connections with timeline analysis.

Part VIII — Network Threat Hunting (10 chapters). Hunting DNS, HTTP, TLS/encrypted traffic, SMB, RDP, network-side SSH, VPN, and DHCP, plus hunting with Zeek logs and analyzing Suricata alerts and PCAP traffic.

Part IX — Cloud Threat Hunting (7 chapters). Identity-first cloud hunting across Microsoft Entra ID, Microsoft 365, AWS CloudTrail, Azure Activity Logs, and GCP Audit Logs, plus cloud identity and federation, and building durable cloud detection, logging, and continuous monitoring.

Part X — Hunting Methodologies (8 chapters). The repeatable craft: building hypotheses, scoping hunts, evidence collection, timeline building, behavior analysis, validation, escalation, and documentation.

Part XI — Purple Team Operations (6 chapters). Measuring and improving real coverage: adversary emulation concepts, detection validation, purple-team ATT&CK mapping, tabletop exercises, SOC collaboration, and continuous improvement.

Part XII — Reporting & Communication (6 chapters). Turning findings into decisions: the executive summary, technical findings, evidence and timelines, detection recommendations, lessons learned, and metrics/KPIs for a hunting program.

Appendices A–H. A working reference set: an ATT&CK tactic cheat sheet, a Sysmon event ID reference, a Windows event ID reference, a Linux log and artifact reference, a Sigma and YARA quick reference, query-language concepts (SPL / EQL / KQL), hunting/detection/incident checklists, and a glossary of key terms.

How every chapter is built

Each chapter follows a consistent, learn-by-doing structure so you always know where to find what you need:

• Learning objectives that frame the outcome
• A grounded explanation of the behavior and the telemetry that exposes it
• Tables and diagrams that make relationships clear
• Detection recipes in a portable, Sigma-style format — each with its likely false positives, because tuning is part of the job
• MITRE ATT&CK mappings for shared classification
• Investigation guidance for working a finding step by step
• Callout boxes — Blue Team Notes, Threat Hunting Tips, Investigation Tips, and Warnings
• Real-world case studies showing the technique in action
• Common mistakes to avoid
• A hunt-hypothesis bank you can run immediately
• A hands-on lab to build the skill
• Review questions to lock it in

What you’ll be able to do

• Run hypothesis-driven, intelligence-driven, and data-driven hunts end to end
• Engineer, test, tune, and maintain detections as code with Sigma and YARA
• Hunt confidently across Windows, Linux, network traffic, and the cloud
• Detect every MITRE ATT&CK tactic, from initial access to impact
• Convert threat intelligence, IOCs, and IOAs into durable, low-false-positive detections
• Master endpoint, network, and identity telemetry — Sysmon, auditd, Zeek, Suricata, SIEM, and EDR
• Reconstruct attacks with multi-source timeline analysis and scope intrusions accurately
• Run purple-team exercises, validate detection coverage against ATT&CK, and continuously improve
• Communicate findings in reports that drive real decisions and measurable program value

Practical, defensive, and ready to use

Everything in this book is oriented toward defense: which log to pull, which field to pivot on, which behavior separates malicious from benign, and how to turn a finding into a tuned, tested control. Hands-on labs run in a modest, isolated environment — a Windows host and a Linux host with Sysmon and auditd, shipping logs into a free SIEM such as Wazuh or the Elastic Stack, with Zeek for network telemetry and free-tier accounts for cloud exercises. A fully clickable table of contents and PDF outline make the book easy to navigate as both a linear course and a day-to-day reference.

Whether you’re running your first hunt or building a hunting program for an enterprise, Threat Hunter gives you both the mental models and the concrete, repeatable craft to catch what everything else misses.

The adversary is already practicing. So should you.
