Hands-On Red Team Tactics

By: Himanshu Sharma, Harpreet Singh

Overview of this book

Red Teaming is used to enhance security by performing simulated attacks on an organization in order to detect network and system vulnerabilities. Hands-On Red Team Tactics starts with an overview of pentesting and Red Teaming, before giving you an introduction to few of the latest pentesting tools. We will then move on to exploring Metasploit and getting to grips with Armitage. Once you have studied the fundamentals, you will learn how to use Cobalt Strike and how to set up its team server. The book introduces some common lesser known techniques for pivoting and how to pivot over SSH, before using Cobalt Strike to pivot. This comprehensive guide demonstrates advanced methods of post-exploitation using Cobalt Strike and introduces you to Command and Control (C2) servers and redirectors. All this will help you achieve persistence using beacons and data exfiltration, and will also give you the chance to run through the methodology to use Red Team activity tools such as Empire during a Red Team activity on Active Directory and Domain Controller. In addition to this, you will explore maintaining persistent access, staying untraceable, and getting reverse connections over different C2 covert channels. By the end of this book, you will have learned about advanced penetration testing tools, techniques to get reverse shells over encrypted channels, and processes for post-exploitation.

Persistence via Cobalt Strike

In Cobalt Strike, we can achieve persistence with the help of Aggressor Scripts. We have already learned about Aggressor Scripts in previous chapters.

Some of the Aggressor Scripts are already available on GitHub; we will use the following one:

Here, we download the scripts on our system and import them into our Cobalt Strike client through the script manager, as shown in the following screenshot:

In the preceding screenshot, we loaded Persistence_Menu. This script creates a new entry in the Beacon menu with all the scripts we downloaded. These scripts can be accessed by right-clicking on the host | Red Team | Persistence, as shown in the following screenshot:

Let's look at the following example. Here, we will use HKCU Run Registry PowerShell Persistence (User Level)...
