Irvin Lemus Workshops


These workshops are structured into a Capture the Flag format, unless specified otherwise, to allow participants to work at their own pace. The techniques demonstrated, with complete step-by-step instructions lead beginners through the easy challenges. There are also harder challenges for more experienced participants. Help will be provided as necessary to ensure everyone learns new techniques.

Participants will usually need a credit card and a few dollars to rent cloud servers on Google Cloud Platform as we will be using Windows and Linux systems. All tools are freely available with the material available after the workshop ends.

Password Cracking

This workshop will give participants an insight into how to use hashcat. In addition, they will engage in various password cracking methods and contests within the workshop. Participants should bring an updated laptop capable of connecting to the Internet with some storage space. While a high-powered laptop is not required nor expected, participants should be able to install whatever they need on the device and have administrative access, should the need arise. Windows, Mac and Linux systems are welcomed.

Web Application Exploitation

This workshop introduces participants to the top 10 web application security risks as defined by OWASP. Participants will be provided guidance into tools and practice environments they can learn from or further sharpen their skills. Participants will attack web applications with Command injection, SQL injection, Cross-Site Request Forgery, Cross-Site Scripting and more. The structure of this workshop is level based, in line with participant's knowledge and comfort level.

Network Analysis with Wireshark

This workshop will introduce participants to Network Analysis by understanding Wireshark. Participants will learn to understand packet activity, abnormalities and anomalies to detect attacks, troubleshoot network problems, and perform network forensics. This workshop is structured as a CTF.

Packetwall for Classrooms

This workshop implements knowledge of Wireshark, Bash scripting, Electronics and Networking in one project. Participants will build a device that detects and notifies when certain packets are found. This project will help participants understand Network Analysis in a different form.
