📖 Overview

This repository maintains a current list of Chrome extensions that have been removed for malware, security violations, or malicious behavior. Since no regularly-updated public database exists for this purpose, this project automates the collection and aggregation of extension removals from multiple sources.

I created this project after searching for an updated list of malicious Chrome extensions and finding that most resources were outdated or incomplete. I'm committed to keeping this database alive and current through automated monitoring and community contributions.
