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.

Automating and remote controlling web browsers as an adversarial technique

Browsers are extremely powerful and offer the capability to store credentials, so you might be lucky just looking through a browser process memory to find cookies, passwords, or other information that could be relevant. We've already explored these scenarios, including how to steal saved passwords from Edge by accessing Windows Credential Manager.

What we will explore now is how to automate a browser so that we can remote control a session.

Based on an example we have been using in this book, let's consider Alice's workstation. Alice uses Windows and browses the web with a variety of browsers, include Edge and Chrome. Unfortunately, her workstation was compromised by Mallory via a phishing attack. Mallory is poised to search for credentials on the machine with similar tactics, but she wants to try something new.

Rather than exfiltrating cookies, why not use Alice's browser directly...
