Chrome Extension Audits Browsers for Malicious Extensions Removed from Web Store

A new browser security tool called Malext Sentry allows users to audit their Chrome installations for extensions that have been removed from the official Web Store, often an indicator of malicious activity. The tool scans installed extensions against Google's removal database and flags potentially risky software. The extension addresses a growing security concern in the browser ecosystem. Malicious extensions regularly slip through Google's review process, accumulate users, and are eventually removed Malext Sentry checks each installed extension against a database of removed items and presents users with a security report. The tool focuses specifically on extensions that were available in the official store before being pulled, distinguishing them from sideloaded software or developer-mode installations. Security researchers have documented numerous cases of malicious extensions harvesting browsing data, injecting advertisements, or redirecting users to phishing sites. The problem has persisted despite Chrome's automated review systems and manual review processes. The tool is available through the Chrome Web Store and operates with minimal permissions, according to its listing.
