To understand how a Chrome extension keylogger works, one must look at the browser's permission system and JavaScript execution.

A malicious Chrome extension operates by abusing the browser’s extension architecture and permissions system. They do not need to install low-level drivers like traditional malware; instead, they operate within the user's browser profile. A. The Mechanism: document.addEventListener keylogger chrome extension work

Chrome extensions interact with web pages and the browser environment using a structured architecture governed by the Chrome Extension APIs. To log keystrokes, a malicious or compromised extension typically follows a specific operational workflow. 1. Requesting Permissions
