Hacking JavaScript Desktop Apps with XSS and RCE
Long are the days since web servers were run by perl scripts and desktop apps 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 workshop 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.
All action, no fluff, improve your security analysis workflow and immediately apply these gained skills in your workplace
In this brief workshop we will give you a few lab samples covering the following topics:
Essential techniques to audit Electron applications
What XSS means in a desktop application
How to turn XSS into RCE in JavaScript apps
Attacking preload scripts
RCE via IPC
