What our analysis found

It's on Surugaya!, used by 1,000 people, showed no malicious code in Extension Auditor's review. It was last updated in September 2026.

Analyst notes

Every network destination in the reviewed code is first-party or the shop the extension exists to query: [domain withheld] (publisher domain, matching the CWS privacy-policy host) for,,, and (:8006, 9411), [domain withheld] page fetches, Firebase FCM for the disclosed price-change notifications (:~4030,), and [domain withheld] using a key the user stores themselves (:8872). There is no Function, no dynamic <script> element, no chrome.cookies, webRequest, declarativeNetRequest, sendBeacon, password-field or keystroke access anywhere in the 20 files, and the affiliate wrapping ([domain withheld] user_id=1063 at:3352 and:7651) fires only on an explicit user click or context-menu action, with a one-time shown at install (:8936) — user-initiated and disclosed, not cookie stuffing. Contradicting the ML score: chrome-stats claims 'removed-from-store' while the listing is active and was updated 2 days ago, and the permhash cluster of 2 at 100% malware is almost certainly two versions of this same extension, so it is self-referential rather than corroborating. Confidence is capped at medium because the bundle is a MB subset of the real MB package: (the content script covering ~100 patterns),,, and the pages were not provided, so I could not audit the page-scraping code itself. Hygiene notes only: the bundled manifest drops the live listing's gcm permission and the [domain withheld] development host, adds optional_host_permissions of <all_urls> plus the two DeepL hosts (optional, user-granted, consistent with user-added shopping sites and the translate feature), and places scripting in optional_permissions rather than permissions as the prompt's summary states — the bundled set is narrower than the published one, not an escalation;:2559 correctly pins event.source===window and the origin allowlist before relaying.

It's on Surugaya!
