Product Description

The growing Internet of Things is bringing more connected devices to consumers every day. These devices, like smart thermostats and smart speakers, are designed to make life easier. This creates new security concerns, since hackers no longer need physical connection to the networks linking the devices, but only need to be in their proximity, to send malicious data to exploit some vulnerability. Wi-Fi technology has big impacts on security, both in terms of perimeter security and client security. In this course we will discuss the security and privacy issues in today’s wireless network including WPA and WPA2 and also fuzz the scanning, authentication and association process of several IoT devices and non-IoT devices.

Who is this course for?

Security professionals and IoT Enthusiasts are welcome to take this course.

Why take it NOW?

There are roughly 8 billion devices connected to the internet as of now and by early 2020, it’s estimated that there were 25 to 35 billion IoT devices worldwide; however, little attention is being paid to the security of the devices. That’s why Wi-Fi Fuzzing is an important and current skill every hacker and pentester should know. 

Why this course?

You will learn multiple tools and techniques in one workshop, and practice all skills in unique labs. This course will also demonstrate how to perform the actual hacking against wireless networks and highlight the top vulnerabilities. This course will offer a hands on opportunity to set up your own Wi-Fi fuzzing lab, perform exploitation using open source tools rather than just watching the videos.

Module 1

Getting started with 802.11 protocol

The 802.11 is perhaps the fastest-changing network protocol around the world. The purpose of this module is to give the basic overview of the 802.11 Standard, in such a way that they will be able to understand the basic concepts, layers, frame structure and protocols. In this module, we will purely focus our efforts on 802.11 protocols.

  • 802.11 overview
  • 802.11 Architecture
  • Components and services
  • 802.11 Layer Modules
  • 802.11 frame Structure
  • 802.11 protocols

Practical graded assignments:

Assignment: We will provide you with multiple choice questions for practice.

Module 2

Introduction to Wi-Fi Fuzzing

The recent rise in complex Wi-Fi vulnerabilities indicates the critical need for effective Wi-Fi protocol testing tools. In this module, we will discuss packet injection for testing Wi-Fi client implementations against vulnerabilities and also introduce some frame fuzzing techniques to capture the packet using Wireshark.
