What our analysis found

Equatio - Math made digital, used by 4,000,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites and can inject scripts into pages. It comes from a trusted publisher and was last updated in September 2026.

The extension is a well-known educational tool (Equatio) by Texthelp, a trusted publisher with a valid email and Google trusted badge. The permissions are necessary for its core functionality of inserting math into various web apps. The code patterns (XMLHttpRequest, innerHTML, eval) are typical of complex web applications using libraries like MathQuill, Desmos, Excalidraw, and Pica; they are not malicious. All data flows go to the publisher's own domains () or to disclosed (Google Analytics), aligning with the CWS-disclosed data collection categories. The ML model likely overfitted on common artifacts and broad but justified permissions.

Read the publisher’s full description
