What our analysis found

Adobe Acrobat: PDF edit, convert, sign tools, used by 337,000,000 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.

This is the official Adobe Acrobat extension (319 million users, Google trusted publisher badge, publisher email chrome-support@). The ML score is 0.00 (low) — the model itself rates it low-risk. All JavaScript files carry Adobe CONFIDENTIAL copyright headers, use standard minified patterns (no obfuscation), and internal analytics events are routed through chrome.runtime.sendMessage to the service worker before reaching endpoints (first-party). The 'Critical' risk-engine score is driven purely by permission presence (webRequest, scripting, <all_urls>), all of which are required for a PDF viewer that integrates with Gmail, Google Drive, ChatGPT, Gemini, and Outlook. The permhash cluster shows malware-flagged peers, directly contradicting the risk label.
