Purple Team Strategies

By: David Routin, Simon Thoores, Samuel Rossier

Overview of this book

With small to large companies focusing on hardening their security systems, the term "purple team" has gained a lot of traction over the last couple of years. Purple teams represent a group of individuals responsible for securing an organization’s environment using both red team and blue team testing and integration – if you’re ready to join or advance their ranks, then this book is for you. Purple Team Strategies will get you up and running with the exact strategies and techniques used by purple teamers to implement and then maintain a robust environment. You’ll start with planning and prioritizing adversary emulation, and explore concepts around building a purple team infrastructure as well as simulating and defending against the most trendy ATT&CK tactics. You’ll also dive into performing assessments and continuous testing with breach and attack simulations. Once you’ve covered the fundamentals, you'll also learn tips and tricks to improve the overall maturity of your purple teaming capabilities along with measuring success with KPIs and reporting. With the help of real-world use cases and examples, by the end of this book, you'll be able to integrate the best of both sides: red team tactics and blue team security measures.

Persistence

Persistence is the kill chain step that represents a key mechanism during an attack. It allows an attacker to capitalize on all the previous steps and efforts they have made. Its goal consists of deploying mechanisms to maintain control over the breached assets inside a network to be resistant to a reboot or credential change. During the investigation, we often see this technique being used after the initial malware execution (often preceded by execution, privilege escalation, and defense evasion) and is the starting point for manual operations and internal discovery.

T1053 – Scheduled task/job

Creating scheduled tasks or jobs is the most simple and flexible sub-technique you can deploy. In this section, we will discuss most of Windows's methods for creating tasks that will execute code at a specific condition or time (this technique is also classified in the execution and privileges escalation parts of the ATT&CK framework). This technique is also...
