What our analysis found

css scanner, used by 3,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can inject scripts into pages. It comes from a trusted publisher and was last updated in March 2023.

Analyst notes

The source code is a straightforward CSS inspection developer tool. The JS files contain only UI construction (createElement, appendChild, innerHTML for the extension's own overlay), CSS rule parsing from the page's own stylesheets via document.styleSheets, keyboard shortcuts, and a 'Copy to CodePen' feature that POSTs to [domain withheld] — a well-known developer SaaS. There is no outbound to any suspicious domain, no credential harvesting, no dynamic code loading, no obfuscation, and no data exfiltration. The ML model over-fit on high js_appendchild (59) and js_innerhtml (20) counts, which are entirely explained by the extension building its own floating overlay DOM. The third-party risk score also rated likelihood (low), corroborating a benign classification. The publisher's 33% malicious rate in other extensions is the one concern, but nothing in this extension's code reflects that pattern.
