Chris Greer - TCP/IP Deep Dive for Ethical Hackers – Featuring Wireshark $1,400 (Early $1,200)
Name of Training:
We’re going to rip open pcaps with Wireshark and learn how this protocol really works.
Almost every attack, intrusion, scan, and exfiltration involves the TCP protocol at some point. Whether we are hacking a system and need to better understand how networks/systems are enumerated and IDS’s do their thing, or we are defending our domain from a botnet attack, a deep understanding of the TCP protocol will help us do our jobs better and faster. In this course, get ready to go deep into TCP. We’re going to rip open pcaps with Wireshark and learn how this protocol really works. Don’t worry, there is FAR more to learn past the three-way handshake! We will learn how the MSS works, receive windows, selective acknowledgements, retransmissions, and much, much more! We will examine how TCP scan, OS enumeration, exfiltration, and C2 traffic looks on the wire, and how TCP fields can help us to filter for it fast. This will be an action-packed, hands-on course for Wireshark beginners as well as seasoned pros who want to pick up some new tricks. There is something for all experience levels in this course, although it will be targeted to the early-intermediate cybersecurity professional.
Chris Greer is a Packet Head. He is a Packet Analyst and Trainer for Packet Pioneer, a Wireshark University partner, and has a passion for digging into the packet-weeds and finding answers to network and cybersecurity problems. Chris has a YouTube channel where he focuses on videos showing how to use Wireshark to examine TCP connections, options, and unusual behaviors, as well as spotting scans, analyzing malware, and other IOC’s in the traffic. His approach to training is that if you aren’t having fun doing something, you won’t retain what you are learning, so he strives to bring as much hands-on and humor to the classroom as possible. Chris remembers what it was like to look at Wireshark for the first time, and knows how complicated packet analysis can be. With that in mind, he has designed an easy-to-follow course that will appeal both to the beginner and more advanced Packet Person.

On my YouTube channel I have a Wireshark Masterclass mini-course that goes over the basics of Wireshark. It has some sample pcaps that they can use to get some hands-on. That is all they will need for a prerequisite. Here is a link to the first (first of nine) video - https://youtu.be/OU-A2EmVrKQ

Laptop with a recent copy of Wireshark from wireshark.org.
