Electron is a cross-platform framework for building desktop applications with web technologies such as JavaScript, HTML, and CSS. Instead of writing separate native apps for each operating system, developers package a browser engine and app logic together so one codebase can run on Windows, macOS, and Linux.
In cyber security, Electron matters because the framework is legitimate and widely trusted, which makes it attractive for abuse. Attackers can trojanize an app, hide code in bundled resources or ASAR archives, and still present a fully working utility that looks normal to users. Defenders should inspect app provenance, verify code signing, watch for unusual child processes or network traffic, and review Electron security settings such as context isolation and limited navigation. Electron is not malware itself; the risk comes from how its packaging and runtime can conceal malicious behavior inside an ordinary-looking desktop app.
