What our analysis found

Flash Player Emulator 2026, used by 200,000 people, showed no malicious code in Extension Auditor's review. Our code review reported 1 finding (1 medium), led by unauthorized data collection. Its permissions mean it can read and change data on all websites and can inject scripts into pages.

Key findings

Medium
Unauthorized Data Collection
The extension sends the URL of the Flash file and the page where it was played to the publisher's analytics server. This collection of browsing data (specific URLs) is not disclosed in the Chrome Web Store privacy disclosures, which only mention 'Location'. Sending detailed page URLs constitutes unauthorized data collection, even though the destination is first-party.

Analyst notes

The extension uses the Ruffle Flash emulator to play legacy SWF content, and all outbound requests go to the publisher's own infrastructure (modernkit.one). No malicious code injection, data exfiltration to third parties, or credential theft is present. However, the extension collects detailed browsing data (page URLs, SWF URLs) for analytics but only discloses 'Location' in its CWS privacy collection categories, which is misleading. This is a privacy disclosure issue, not malicious intent. The ML risk signals are primarily attributed to the large Ruffle bundle and the broad permissions necessary for Flash emulation.

Hey Devs! You’ve built some serious telemetry into this extension, it sends all kinds of data to your servers. WHY? Are you tracking what people watch on a map? Fine — but it seems the extension can also send you more than that, including potentially sensitive data. There’s no clear sign of outright data theft (cookies, keylogging, etc.), but even so, this telemetry feels far more extensive than necessary. The extension had one job: to run Flash content in an emulated environment. I could accept a simple map-based usage statistic, that's all. I’ve castrated your extension down for my own use. Thanks for the work — I didn't have to build the core functionality from scratch myself.
