What our analysis found

United Airlines MileagePlus 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 October 2026.

Analyst notes

The extension is a legitimate MileagePlus Shopping button for United Airlines, published by a trusted developer (Cartera). The broad permissions (webRequest, cookies, scripting) are necessary for its core functionality: detecting merchant sites, injecting reminders, and applying coupons. All network communication targets the publisher's own domains ([domain withheld], [domain withheld]) and first-party analytics (Google Analytics) which is disclosed in the CWS data collection categories. No unauthorized data exfiltration, code injection, or malicious behavior found. The ML model likely overfitted on the permission combination and minified bundle patterns, but the permhash cluster has 0% flagged malware and the publisher is trusted, corroborating a benign verdict.
