Mastering Kali Linux for Advanced Penetration Testing – Fourth Edition - Fourth Edition

By: Vijay Kumar Velu

Overview of this book

Remote working has given hackers plenty of opportunities as more confidential information is shared over the internet than ever before. In this new edition of Mastering Kali Linux for Advanced Penetration Testing, you’ll learn an offensive approach to enhance your penetration testing skills by testing the sophisticated tactics employed by real hackers. You’ll go through laboratory integration to cloud services so that you learn another dimension of exploitation that is typically forgotten during a penetration test. You'll explore different ways of installing and running Kali Linux in a VM and containerized environment and deploying vulnerable cloud services on AWS using containers, exploiting misconfigured S3 buckets to gain access to EC2 instances. This book delves into passive and active reconnaissance, from obtaining user information to large-scale port scanning. Building on this, different vulnerability assessments are explored, including threat modeling. See how hackers use lateral movement, privilege escalation, and command and control (C2) on compromised systems. By the end of this book, you’ll have explored many advanced pentesting approaches and hacking techniques employed on networks, IoT, embedded peripheral devices, and radio frequencies.

Testing for S3 bucket misconfiguration

S3 is typically used by organizations to store documents, code, file uploads, and so on and so forth. Typically, a bucket can be either public or private. When public, all users can list the contents, and when private, only the selected set of users can list the contents. Although S3 exploitation has always been in the news, notably for developers storing mission-critical information in a bucket marked as “public.” In this section, we will explore identifying S3 buckets and exploiting misconfiguration to gain access to the internal AWS infrastructure.

To practice S3 bucket misconfiguration, we will be setting up a vulnerable S3 instance using CloudGoat by running the following command within the CloudGoat Docker image:

./cloudgoat create cloud_breach_s3

Once the setup is complete, testers should be able to see the following message from the deployment tool with the AWS account ID and the target IP address, as shown...
