Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the browser bundle can target Russian-language users visiting matching domains. It disables page interaction and plays externally hosted audio in a loop. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T06:23:22.861Z - **Finished:** 2026-09-13T06:24:22.761Z - **Download time:** 1015 ms - **Static scan time:** 13602 ms - **AI review time:** 45282 ms - **Total time:** 59900 ms The recorded confidence comes from the underlying analysis.

It disables page interaction and plays externally hosted audio in a loop. - **Trigger:** A consumer imports the package in a browser; the visitor has a Russian language setting, uses a matching domain, and has a three-day-old local marker. - **Impact:** Targeted users lose page pointer interaction and receive unwanted looping audio. - **Evidence paths:** package.json, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T06:24:22.761Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Top-level conditional browser disruption with injected looping remote audio. - **Attack narrative:** The package declares dist/index.js as its main entry. That bundle executes a top-level condition for Russian-language browsers on selected domain suffixes. It records a local marker, then after three days disables pointer events on the whole page, adds an audio element, and loops remote audio. This is targeted protestware delivered by importing a UI package. - **Rationale:** The package contains concrete, import-time targeted browser sabotage unrelated to import/export UI functionality. The absence of an install hook does not mitigate this malicious runtime behavior. - **Network endpoints:** https://flag-gimn.ru/wp-content/uploads/2021/09/Ukraina.mp3 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The declared runtime entry bundle contains a top-level browser trigger targeting Russian-language users on Russian-associated domains., After three days, the trigger disables all page pointer interaction and injects looping audio from an external host., The behavior runs when the package bundle is imported, not through a user-invoked component action. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The inspected network request for the protest payload is limited to an audio URL; no credential exfiltration was found. ## Affected versions and remediation This report applies to @esvndev/es-react-import-export@1.2.37. - Avoid installing @esvndev/es-react-import-export@1.2.37. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
