What our analysis found

CSS validator showed no malicious code in Extension Auditor's review. It was last updated in November 2024.

Analyst notes

Every line of this extension's own code is a CSS-validation UI: only opens the bundled page on action click, sets an tab to [domain withheld] and proxies a {lang_last_used} object to chrome.storage.local, and makes exactly one network call (jQuery.ajax to [domain withheld], line 300 of the bundle) carrying only the CSS the user typed into the Ace editor; with manifest permissions limited to `storage`, no host_permissions, no content_scripts and no, the package is architecturally incapable of the 'persistent access to user sessions' the IoC source alleges. The bundled manifest matches the published manifest exactly (MV3, `storage` only), and all four bundled libraries are byte-identical to upstream releases (ace-builds 1.36.3, jQuery 3.7.1, Bootstrap 5.3.3 CSS — sha256 verified against jsdelivr/[domain withheld]), so the ML regex hits are upstream-library and boilerplate artifacts. Contradicting signals that keep this at medium rather than false_positive: the ID is genuinely listed in the LayerX 40+-malicious-extensions table, but that research reverse-mapped DomainTools' suspicious-*domain* list to CWS metadata rather than reviewing code, and its stated attribution criteria (non-Gmail publisher domain, support@domain format) are generic; the commented-out leftover `[domain withheld] in does place this developer in the same mass-published [domain withheld]-tool cluster as other listed IDs ([domain withheld], [domain withheld], [domain withheld]), and the operator retains a server-controlled surface via the response rendered with $('[data-res]').html(data.text) plus the install tab, so a future update could add capability that v1.5, v1.6 and v1.8 do not have. issues, not security findings: the star widget routes 1-3 stars to [domain withheld] and only 4-5 stars to the CWS review page (review gating), the publisher support mailbox has no MX records, and lang="ru" on an English page plus a Google-Docs 'privacy policy' are low-effort publishing.
