Most of us have used Wireshark either academically or professionally for traffic analysis. Its a great tool for microscopic analysis of what is happening in the network. However, its greatest strength is also its greatest weakness i.e. it is extremely difficult to do macroscopic analysis, create custom reports, extract only certain fields from packets for offline analysis etc. This is where Tshark comes in! Tshark is a command line tool created by the Wireshark team and shares the same powerful parsing engine as Wireshark. It is capable of doing most things we’ve come to love Wireshark for, but with the “from command line” advantage. This makes it ideal for batch analysis, offline processing and routine automation of traffic analysis tasks. In this course, we will explore many of these capabilities. It is assumed you have a basic working knowledge of Wireshark and traffic analysis.

This course will familiarize students with all aspects of reverse engineering (reversing) Linux 32-bit applications for the purposes of locating flaws and developing exploits. By the end of this course students will be able to understand, locate, and exploit all of the common flows in 32-bit Linux software. These flaws include, but are not limited to, buffer overflow, heap overflows, format string flaws, section overflows, and kernel flaws. Along the way students will gain a better understanding of how Linux 32-bit applications work and will be exposed to a number of common reversing tools such as specialized debuggers (IDA Pro) and fuzzers.  As always, you will also learn how to leverage Python and other scripting tools in order to automate the discovery and exploitation of software flaws.

Linux dominates the Server, Embedded and now the Internet of Things (IoT) device market. In recent times, embedded systems and IoT devices in particular have been the weapons of choice in online attacks: botnets like Mirai and Reaper to name a few. Soon the simple attack vectors that these botnets and malware use get patched, it is obvouis that the attacker will move and hide his tools in Kernel mode. This course will teach Red-Blue teams how kernel mode attack kits work and what to go about protecting their systems against it. We will use examples on x86_64, ARM and MIPS based architectures.

This entire course will be run on the latest Linux Kernel 4.15.x. This course is completely hands-on and everything will be taught with practical examples in the form of Kernel Modules written in C. You can however follow this course with a basic knowledge of Linux as we discuss everything from the very basics.

This course is a deep dive into Embedded/IoT firmware where we will start from the very basics – understand the multistage boot process, the kernel and root filesystem, how to build them with a custom toolchain and how they can be compromized with user and kernel mode backdoors/rootkits. We will be using the latest 4.15.x kernel for this course on an ARM architecture board.

In this Hacker Project we will learn how to create an SMS controlled Pentesting Bot! This bot will be able to run nmap scans on your command from anywhere in the world 🙂

Key concepts you will learn:

• Raspberry Pi 3 and Raspbian installation Basics
• Working with the Raspberry Pi in headless mode
• Using Hologram.io’s Nova device with their IoT SIM
• Sending and receiving SMS from/to the device over cellular networks
• Running custom automation tasks based on the remote controller
