Advanced Pwning & Fixing of Node.js and Electron apps, shells, injections and fun!

This course is the culmination of years of experience gained via practical penetrationtesting of JavaScript 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 Electron and Node.js apps. This course provides participants with actionable skills that can be applied immediately from day 1.

Please note our courses are 90%+ 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 training portal, for which you keep ​lifetime access​, as well as ​unlimited email support​.

Each day starts with a brief introduction to the JavaScript platform (i.e. Node.js, Electron)for that day 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 specifically on Node.js: We start with understanding the platform andthen deep dive into static and dynamic analysis of the applications at hand. This day is packed with hands on exercises and CTF-style challenges.

Day 2: Focused on Electron: We start with understanding Electron and various security considerations. We then focus on static and dynamic analysis of the applications athand. The day is filled with hands on exercises ending with a CTF for more practical fun.

Why should you take this course?

This is ​more​ than a physical attendance course: You get the physical course but also lifetime access​ to a training portal 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 training portal 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 of ways to identify the attack surface of Node.js and Electron 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.

Upon Completion of this training, attendees will know

Completing this training ensures attendees will be competent and able to:

  • Review and tamper network communications to exploit security vulnerabilities
  • Bypass certificate and public key pinning protections on Electron apps
  • Bypass inadequate Node.js and Electron defences
  • Analyze Node.js and Electron apps from a blackbox perspective
  • eview Node.js and Electron app source code to identify security flaws
  • Perform Node.js and Electron app security review

This course is for beginners, intermediate and advanced level students. While beginnersare introduced to the nuances of Node.js and Electron 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 morea dvanced students polish their skills

The course is crafted in a way that regardless of your skill level you will significantly improve your JavaScript security skills:

If you are new and cannot complete the labs during the class, that is OK, as you keep training portal access, you will learn a lot in the class but can continue from home withthe training portal.

If you are more advanced in JavaScript security you can try to complete the labs in fulland then take the CTF challenges we have for each day, you will likely also attempt to complete some exercises from home later :)

What to expect

Lifetime access to training portal (including all future updates), unlimited email support,access to private groups to communicate with other students, interesting apps from various countries.

A fully practical class that will seriously improve your Node.js, Electron and JavaScript 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 canapply as soon as you go back to your workplace, making security testing of Node. js/Electron/JavaScript apps as efficient as possible. Intensive hands-on exercises that challenge you to deep dive into the world of JavaScript security.

What not to expect

This is ​more​ than a physical attendance course: You get the physical course but also lifetime access​ to a training portal with step-by-step video recordings, slides and lab exercises, ​including all future updates for free​.

The course does ​not​ cover: Node.js or Electron 0-day, 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.
