Overview of this book

Effective threat investigation requires strong technical expertise, analytical skills, and a deep understanding of cyber threats and attacker techniques. It's a crucial skill for SOC analysts, enabling them to analyze different threats and identify security incident origins. This book provides insights into the most common cyber threats and various attacker techniques to help you hone your incident investigation skills. The book begins by explaining phishing and email attack types and how to detect and investigate them, along with Microsoft log types such as Security, System, PowerShell, and their events. Next, you’ll learn how to detect and investigate attackers' techniques and malicious activities within Windows environments. As you make progress, you’ll find out how to analyze the firewalls, flows, and proxy logs, as well as detect and investigate cyber threats using various security solution alerts, including EDR, IPS, and IDS. You’ll also explore popular threat intelligence platforms such as VirusTotal, AbuseIPDB, and X-Force for investigating cyber threats and successfully build your own sandbox environment for effective malware analysis. By the end of this book, you’ll have learned how to analyze popular systems and security appliance logs that exist in any environment and explore various attackers' techniques to detect and investigate them with ease.

Required tools for analysis

After acquiring and preparing the required hardware and software to build your private sandbox, let us introduce the required tools to analyze the suspected files in the sandbox. The tools are divided into two types:

  • Static analysis tools
  • Dynamic analysis tools

Static analysis tools

Static analysis tools are the tools that will be used to collect and analyze information about the suspected file without execution. The static analysis tools that we will install on our private sandbox are as follows:

  • YARA: YARA is a tool aimed at (but not limited to) helping malware researchers identify and classify malware samples. We will use the YARA tool to scan the suspected files for certain malware characters to identify the malware category and family if detected. Examples of malware categories are ransomware, Trojans, and InfoStealer, and examples of malware families are Redline, Ryuk, and Zeus. To download the YARA tool, follow this link...
