The extension declares zero permissions in its manifest (no host_permissions, no sensitive APIs), making it structurally incapable of accessing browsing data, cookies, or page content. All ML signals are fully explained by legitimate code: the 9 `fromCharCode` hits and 3 `eval` calls originate exclusively from ` `, an emscripten-compiled build of the open-source KissFFT library; the 59 `innerHTML` hits are UI label updates (numeric slider values, localized strings) inside the extension's own popup; the `html_base64_obfuscation` hit is a `data:;` empty favicon in; and the signals come from shared utility functions (`fetchUpload`, `fetchDrive` in ` `) that read their target URL from a `data-api-server` DOM attribute — an attribute that is not set in any HTML file in this bundle, meaning the functions are dead code here. The only external URLs in the extension are `[domain withheld]` (publisher's own domain) and the Web Store rating link constructed in ` `. The elevated publisher-level malicious rate (32%) does not change what this extension's own code does — it is a legitimate local audio editor built on.
