In this workshop you’ll learn some of the fundamental techniques of network hacking and how you can use them to find computers and services running on a network, intercept local network communication, read and manipulate traffic, and break some of commonly deployed protocols at the network layer.

You’ll solve a series of challenges, each in a contained virtualized network where it’s just you and your targets. We’ll start with a networking crash course to introduce you to packets and their layers, as well as how to use Wireshark to dig in and explore further.

Topics we’ll cover:

• Network crash course in peeling back the layers
• Network sniffing and the world of broadcast traffic
• Network scanning and finding your next target
• Man-in-the-middle attacks through ARP poisoning
• DNS poisoning so that your too can be facebook.com

What you need to bring:
* A laptop with Linux or a Linux VM (MacOS also works, but have a VM installed as a backup).
* Some basic experience with command line tools.
* These software tools (detailed installation instructions at https://notebook.naumachiactf.com):
* OpenVPN: Connect to the challenges you will be hacking
* Wireshark (tcpdump also works): Capture and dissect network traffic
* netcat (nc): Swiss-army-knife of networking
* nmap: Scan and search for vulnerable targets
* ettercap: Man-in-the-middle attack tool and network attack platform
* python3 (optional): Build new attack tools
