Electron has evolved significantly over the years, adopting safer defaults and introducing security mechanisms aimed at reducing the risk of application compromise. While many of the well-known "secure by default" issues have been addressed, modern Electron applications remain vulnerable due to insecure implementation patterns, unsafe IPC designs, dangerous preload exposure, protocol handler abuse, and misplaced trust assumptions between renderer and main processes. This talk explores how contemporary Electron applications can still be exploited even with recommended security configurations enabled. Through hands-on demonstrations using DVEA — a purpose-built vulnerable Electron application designed for security training and research — attendees will learn how common development mistakes can transform seemingly hardened applications into viable attack surfaces.
