All source code is consistent with a legitimate currency converter and calculator popup extension. The two network destinations are `[domain withheld]` and `[domain withheld]`, both well-known public currency rate APIs, and no user data is sent — only GET requests for exchange rates. The `js_hex_obfuscation` count of 78 that drove the ML score traces entirely to floating-point numbers in (e.g., `0.88131820474538`) whose decimal digits happen to match hex-character regex patterns, not to any actual obfuscation; the one genuinely hex-encoded string in (`_0x37db`) is fully commented out and decodes to the old Yahoo Finance API endpoint replaced years ago. The chrome-stats score (Impact) and our own risk engine (0.00) both corroborate a clean extension; the publisher's other two flagged extensions are not evidence this one is malicious.
