The loader fetches computed remote content and dynamically executes reconstructed code. - **Trigger:** A user opens or serves index.html. - **Impact:** Arbitrary JavaScript can run in the visitor's browser origin. - **Evidence paths:** index.html, assets/index-\_E4fBqHJ-eac502ad.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-17T17:54:04.220Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** page-load remote script injection and dynamic remote-code execution - **Attack narrative:** When the included web page is opened, it immediately loads JavaScript from c.vipersfutbol.com. Its obfuscated main bundle also fetches a computed URL and invokes new Function on reconstructed values, creating a remote-controlled execution path in the page context. There is no npm install hook, but the runtime behavior is concrete and unsafe. - **Rationale:** The package embeds an undisclosed external script and an obfuscated fetch-plus-new-Function loader activated by opening its page. This is a concrete remote code execution surface, not merely a benign browser dependency. - **Files touched:** index.html, assets/index-\_E4fBqHJ-eac502ad.js - **Network endpoints:** https://c.vipersfutbol.com/script.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.html loads an untrusted external script from c.vipersfutbol.com on page load., The primary bundled entry is heavily obfuscated and invokes new Function with reconstructed values., The same entry fetches a computed remote URL, enabling remotely supplied runtime behavior. - **Evidence against:** package.json contains only name and version; no npm lifecycle hooks or Node entrypoints are declared., No install-time filesystem or process-execution behavior was found. ## Public findings ### 1.
