Advanced Pwning & Fixing of Node.js & Electron apps, shells, injections and fun!
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. As we try to keep both new and advanced students happy, the course is very comprehensive and we have not met any student able to complete all challenges during the class, therefore training continues after the course through our frequently updated training portal, for which you keep lifetime access, as well as unlimited email support.
Day 1: Focused specifically on Node.js. We start with understanding the platform and then 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 at hand. The day is filled with hands on exercises ending with a CTF for more practical fun.
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 the training portal.
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;
- Node.js basics;
- Electron basics.
A laptop with the following specifications:
- Ability to connect to wireless and wired networks;
- Ability to read PDF files ;
- Administrative rights: USB allowed, the ability to deactivate AV, firewall, install tools;
- Knowledge of the BIOS password, in case VT is disabled;
- Minimum 8GB of RAM (recommended: 16GB+);
- 60GB+ of free disk space (to copy a lab VM and other goodies);
- VirtualBox 6.0 or greater, including the “VirtualBox Extension Pack”.
Attendees will be provided with:
- Lifetime access to training portal with all course materials;
- Unlimited access to future updates and step-by-step video recordings;
- Unlimited email support, if you need help while you practice at home later;
- Interesting vulnerable apps to practice;
- Digital copies of all training material;
- Custom Build Lab VMs;
- Purpose Build Vulnerable Test apps;
- Source code for test apps.
Who should attend this training?
This course is for beginners, intermediate and advanced level students. While beginners are 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 more advanced students polish their 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 with the training portal.
This course will take any student and make sure that:
- The general level of proficiency is much higher than when they came;
- The skills acquired can be immediately applied to Node.js/Electron app security assessments;
- Skills can be sharpened via continued education in our training portal for free;
- The student is equipped to defeat common Node.js and Electron app assessment challenges;
- Advanced students will come out with enhanced skills and more efficient workflows;
- The skills gained are highly practical and applicable to real-world assessments;
- Review of Common Flaws in Source Code and at Runtime;
- Electron - Modification of App Behavior Through Code/Configuration Changes;
- Electron/Node.js - Interception of Network Communication and MitM-proxy techniques to find security flaws in these platforms;
- Platform-specific attack vectors against Node.js apps & mitigation;
- Platform-specific attack vectors against Electron apps & mitigation;
- CTF Challenges for Attendants to Test Their Skills.
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;
- Review Node.js and Electron app source code to identify security flaws;
- Perform Node.js and Electron app security reviews;
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.
