Course Abstract
This course is a 100% hands-on deep dive into the OWASP Security Testing Guide and relevant items of the OWASP Application Security Verification Standard (ASVS), so this course covers and goes beyond the OWASP Top Ten.
Long are the days since desktop apps were written in Delphi. What is common between Microsoft Teams, Skype, Bitwarden, Slack and Discord? All of them are written in Electron: JavaScript on the client.
JavaScript Desktop apps share traditional attack vectors and also introduce new opportunities to threat actors. This course will teach you how to review JavaScript desktop apps, showcasing Node.js and Electron but using techniques that will also work against any other desktop app platform. Ideal for Penetration Testers, Desktop app Developers as well as everybody interested in JavaScript/Node.js/Electron app security.

Training Abstract
This course is the culmination of years of experience gained via practical penetration testing of JavaScript Desktop applications as well as countless hours spent doing research. We have structured this course around the OWASP Security Testing Guide, it covers the OWASP Top Ten and specific attack vectors against JavaScript Desktop apps. This course provides participants with actionable skills that can be applied immediately from day 1.
Please note our courses are 100% hands-on, we do not lecture students with boring bullet points and theories, instead we give you practical challenges and help you solve them, teaching you how to troubleshoot common issues and get the most out of this training. Training then continues after the course through our frequently updated course material, for which you keep lifetime access, as well as unlimited email support.

Each section starts with a brief introduction to the JavaScript platform (i.e. Node.js, Electron) for that section and then continues with a look at static analysis, moves on to dynamic checks finishing off with a nice CTF session to test the skills gained.
Day 1: Focused on Hacking JavaScript Desktop Apps: We start with understanding JavaScript Desktop apps and various security considerations. We then focus on static and dynamic analysis of the applications at hand. The section is filled with hands-on exercises ending with a CTF for more practical fun.
Day 2: Dedicated to instrumentation and Advanced JavaScript Desktop App attacks: We cover advanced usage of instrumentation to debug and workaround typical assessment problems and then move on to cover attacks specifically targeting Electron and other platforms such as interesting XSS scenarios, multiple edge cases to gain RCE, local & remote attacks, prototype pollution, and more. The day is full of hands-on exercises and ends with CTF-style open challenges for additional practice.

Course Pre-requisites
This course has no prerequisites as it is designed to accommodate students with different skills:
Advanced students will enjoy comprehensive labs, extra miles and CTF challenges
Less experienced students complete what they can during the class, and can continue at their own pace from home using their lifetime course access.
This said, the more you learn about the following ahead of the course, the more you will get out of the course:
Linux command line basics
Basic knowledge of Node.js, Electron or JavaScript is not required, but would help.
Who Should Attend
Any Desktop App developer, penetration tester or person interested in JavaScript Desktop apps, Node.js, Electron or JavaScript security will benefit from attending this training regardless of the initial skill level:
This course is for beginners, intermediate and advanced level students. While beginners are introduced to the nuances of JavaScript Desktop App security from scratch, intermediate and advanced level learners get to perfect both their knowledge and skills on the subject. Extra mile challenges are available in every module to help more advanced students polish their skills.
The course is crafted in a way that regardless of your skill level you will significantly improve your JavaScript App security auditing skills:
If you are new and cannot complete the labs during the class, that is OK, as you keep course access, you will learn a lot in the class but can continue from home with your lifetime course access.
If you are more advanced you can try to complete the labs in full and then take the CTF challenges we have for each section, you will likely also attempt to complete some exercises from home later :)
What to Expect
Lifetime access to all course material (including all future updates), unlimited email support, access to private groups to communicate with other students, and interesting apps from various countries.
A fully practical class that will seriously improve your JavaScript Desktop App security knowledge and skills, regardless of the skill level you come in with. Battle-tested tips and tricks that take your abilities to the next level and that you can apply as soon as you go back to your workplace, making security testing of JavaScript Desktop apps as efficient as possible.
Intensive hands-on exercises that challenge you to deep dive into the world of JavaScript App security.
What Not to Expect
This is more than a usual online course: You get lifetime access to all training course materials with step-by-step video recordings, slides and lab exercises, including all future updates for free.
The course does not cover: 0-days, Windows/Linux/Mac OS exploits, x86 exploit writing, writing buffer or heap overflows.
Do not expect the teachers to be talking through slides most of the time: This class is practical not theoretical, the teachers don’t bore you with slides all the time, instead you do exercises all the time and the teachers help you solve the challenges you face as you complete them.

Why should you take this course?
This is more than a usual online course: You get lifetime access to all course materials with step-by-step video recordings, slides and lab exercises, including all future updates for free.
Students can take the course at their own pace and lifetime access ensures topics can be reviewed on an ad-hoc basis as required by the student online after the course.
This training has been built from real issues seen in real applications, not fabricated vulnerabilities that you will never see in practice.
The goal is to start from the basics and ensure that each student comes out of the training with a significantly higher level of proficiency in the artistry of pentesting.
Students will be taught ways to identify the attack surface of JavaScript Desktop apps, exploit interesting vulnerabilities and means to fix them. The course walks students through the process of performing security audits of JavaScript apps. The training also covers effective identification, exploitation and mitigation of common vulnerability patterns against these platforms.
As the course has been written and carefully created by professional penetration testers, after many years of experience, many practical tips will be shared to leverage automation and make penetration testing more efficient as soon as the student goes back to their workplace.
