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.

Monitoring and alerting for logins and login attempts

If you've ever participated or plan to participate in a red team versus red team operation, then the following information might be quite useful in case your machine gets popped (either by another red team or a real adversary).

If you have SSH (or other remote access endpoints) enabled on hosts, there are some ways to explore and add mitigations in case your keys or password are compromised, or someone leverages an unknown or unpatched vulnerability to login. These are some basic ideas to explore that may trigger some more ideas on your side.

Receiving notifications for logins on Linux by leveraging PAM

Pluggable Authentication Modules (PAMs) are used on Linux and macOS to configure and change login behavior. It is a possible place to add additional logging.

As an example, if, for some reason, you have endpoints such as SSH exposed, PAM can help with additional alerting. You can add additional logging and notifications...
