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.

Attacking WPA and WPA2

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access 2 (WPA2) are wireless security protocols that were intended to address the security shortcomings of WEP. Because the WPA protocols dynamically generate a new key for each packet, they prevent the statistical analysis that caused WEP to fail. Nevertheless, they are vulnerable to some attack techniques as well.

WPA and WPA2 are frequently deployed with a pre-shared key (PSK) to secure communications between the AP and the wireless clients. The PSK should be a random passphrase of at least 13 characters in length; if not, it is possible to determine the PSK using a brute-force attack by comparing the PSK to a known dictionary. This is the most common attack.

Note that if configured in the Enterprise mode, which provides authentication using a RADIUS authentication server, it might require a more powerful machine to crack the key or perform different types of MiTM attacks.
