What our analysis found

WPS PDF - Read, Edit, Fill, Convert, and AI Chat PDF with E…, used by 8,000,000 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 published by a trusted developer (, Google trusted publisher badge, featured listing) with 7 million users, high rating, and a privacy policy that discloses collection of location and user activity. The permissions, while broad, are consistent with a PDF that needs to interact with web pages and a native desktop application. The injected content scripts only target specific partner sites (Google Scholar,) and implement promotional popups that are first-party marketing. No exfiltration to third parties or malicious behavior found in the provided source files. The ML model's low score (0.00) and the clean permhash cluster (0% flagged) further support benign classification.
