The extension contains only a manifest and a single CSS file () injected exclusively into [domain withheld]. There is zero JavaScript, no declared permissions, no network requests, no data collection, and no eval or dynamic code execution anywhere — CSS is structurally incapable of exfiltrating data or intercepting credentials. The ML score of 0.90 is a clear false positive driven by the presence of content_scripts in the manifest and the high malware rate in the zero-permissions permhash cluster, not by any actual malicious behaviour. The third-party chrome-stats score (impact) and our own risk engine (score 0.00) both corroborate benign status; the publisher's malicious track record on other extensions is noted but this specific extension's code is unambiguously harmless.
