What our analysis found

Adblock from Capital One Shopping, used by 100,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites, can inject scripts into pages and can observe network requests. It comes from a trusted publisher and was last updated in September 2026.

The extension is a legitimate adblocker from Capital One Shopping. Broad permissions are necessary for its core functionality (blocking ads, modifying network requests, injecting scripts). All identified data collection (ad metrics, shopping integration) is sent to the publisher's own domain () and matches the CWS-disclosed categories (personally identifiable information, location, user activity, website content). Code obfuscation is typical for protecting proprietary adblocking logic. No evidence of unauthorized third-party communication, credential theft, remote code execution, or other malicious behavior was found.
