Cybersecurity Attacks – Red Team Strategies

By: Johann Rehberger

Overview of this book

It's now more important than ever for organizations to be ready to detect and respond to security events and breaches. Preventive measures alone are not enough for dealing with adversaries. A well-rounded prevention, detection, and response program is required. This book will guide you through the stages of building a red team program, including strategies and homefield advantage opportunities to boost security. The book starts by guiding you through establishing, managing, and measuring a red team program, including effective ways for sharing results and findings to raise awareness. Gradually, you'll learn about progressive operations such as cryptocurrency mining, focused privacy testing, targeting telemetry, and even blue team tooling. Later, you'll discover knowledge graphs and how to build them, then become well-versed with basic to advanced techniques related to hunting for credentials, and learn to automate Microsoft Office and browsers to your advantage. Finally, you'll get to grips with protecting assets using decoys, auditing, and alerting with examples for major operating systems. By the end of this book, you'll have learned how to build, manage, and measure a red team program effectively and be well-versed with the fundamental operational techniques required to enhance your existing skills.

Cookies are powerful and, at times, even more powerful than passwords. If an adversary steals the right cookies, they can gain unfettered access to resources. Multi-factor authentication does not protect us in this case as cookies are issued past the multi-factor step.

Additional challenges for critical operations within the web application or service can help further protect us from adversaries.

The Pass the Cookie technique is a powerful session hijacking tactic. The following diagram shows what Pass the Cookie means at a high level:

Figure 8.1: Pass the Cookie explained

The preceding diagram highlights the attack conceptually. The basic steps to perform these session-hijacking techniques are as follows:

  1. Mallory, the adversary, compromises an organization by phishing a sales employee.
  2. Afterward, Mallory laterally moves through the environment.
  3. Once Mallory reaches a powerful workstation...
