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.

This type of asset will host C2 solutions and will be responsible for serving and communicating with compromised assets sitting internally within the organization. Essentially, it will host our payload, and once it has been executed on an asset, a communications link will then be established with this server's backend or moved to another type of server.

We can split C2 assets into the following categories, which are based on their intent and roles:

  • Phishing C2
  • Short-term C2
  • Long-term C2

Phishing C2

As its name suggests, this type of C2 can be used in the early stage of the execution phase to phish our target by hosting a fake authentication page or payload to download.

The intent of this server is to send the first stage of our attack. Then, once the payload is executed or the credentials are harvested,...
