Hands-On AWS Penetration Testing with Kali Linux

By: Karl Gilbert, Benjamin Caudill

Overview of this book

The cloud is taking over the IT industry. Any organization housing a large amount of data or a large infrastructure has started moving cloud-ward — and AWS rules the roost when it comes to cloud service providers, with its closest competitor having less than half of its market share. This highlights the importance of security on the cloud, especially on AWS. While a lot has been said (and written) about how cloud environments can be secured, performing external security assessments in the form of pentests on AWS is still seen as a dark art. This book aims to help pentesters as well as seasoned system administrators with a hands-on approach to pentesting the various cloud services provided by Amazon through AWS using Kali Linux. To make things easier for novice pentesters, the book focuses on building a practice lab and refining penetration testing with Kali Linux on the cloud. This is helpful not only for beginners but also for pentesters who want to set up a pentesting environment in their private cloud, using Kali Linux to perform a white-box assessment of their own cloud resources. Besides this, the book covers a large variety of AWS services that are often overlooked during a pentest — from serverless infrastructure to automated deployment pipelines. By the end of this book, you will be able to identify possible vulnerable areas efficiently and secure your AWS cloud environment.

Privilege Escalation of AWS Accounts Using Stolen Keys, Boto3, and Pacu

An important aspect of pentesting AWS environments is the process of enumerating what permissions your user has, and then escalating those privileges, if possible. Knowing what you have access to is the first battle, and it will allow you to formulate an attack plan in the environment. Next is privilege escalation, where if you can gain further access to the environment, you can perform more devastating attacks. In this chapter, we will dive into the Python boto3 library to learn how to make AWS API calls programmatically, learn how to use it to automate the enumeration of our permissions, and then finally, learn how to use it to escalate our permissions if our user is vulnerable to escalation.

The enumeration of our permissions is very important for a multitude of reasons. One of these is that we will avoid...
