Mastering Kali Linux for Advanced Penetration Testing - Third Edition

By: Vijay Kumar Velu, Robert Beggs

Overview of this book

This book takes you, as a tester or security practitioner, through the reconnaissance, vulnerability assessment, exploitation, privilege escalation, and post-exploitation activities used by pentesters. To start with, you'll use a laboratory environment to validate tools and techniques, along with an application that supports a collaborative approach for pentesting. You'll then progress to passive reconnaissance with open source intelligence and active reconnaissance of the external and internal infrastructure. You'll also focus on how to select, use, customize, and interpret the results from different vulnerability scanners, followed by examining specific routes to the target, which include bypassing physical security and the exfiltration of data using a variety of techniques. You'll discover concepts such as social engineering, attacking wireless networks, web services, and embedded devices. Once you are confident with these topics, you'll learn the practical aspects of attacking user client systems by backdooring with fileless techniques, followed by focusing on the most vulnerable part of the network – directly attacking the end user. By the end of this book, you'll have explored approaches for carrying out advanced pentesting in tightly secured environments, understood pentesting and hacking techniques employed on embedded peripheral devices.

About Packt


UART stands for Universal Asynchronous Receiver/Transmitter. It is one of the first modes of communication to computers: it goes back to 1960, when it was used to connect minicomputers for teletypewriter machines (teletypes). The main purpose of UARTs is to transmit and receive the serial data just like a standalone integrated circuit; it is not a protocol as SPI (Serial Peripheral Interface) or I2C (Inter-Integrated circuit). It is typically used by manufacturers to connect microcontrollers to store and load programs. Every UART device has its own advantages and disadvantages. The following are the advantages of UART:

  • Two wires only, so pretty straightforward one is transmit (TX) and another is Receive (RX)
  • There is no need for a clock signal
  • Error checking can be performed by parity bit
  • If both sides are set up then the structure of the data packet can be changed
  • Widely used due to the availability of its documentation throughout the internet

It has the following limitations:

  • Testers cannot...
