It retrieves an unverified executable payload, writes it to temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the importing process's permissions. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-07T11:24:24.992Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, chmod, and detached shell execution - **Attack narrative:** Requiring index.js imports \_polyfill.js, which immediately runs. It fetches a platform-specific payload from rotating worker hosts or assembles it from DNS TXT records, saves it under a disguised temporary filename, makes it executable on Unix, and starts it detached through a shell or cmd.exe. The apparent telemetry module repeats this loader design. - **Rationale:** The package performs concealed remote payload retrieval and execution during ordinary import, without a user-invoked setup action. This is concrete malware behavior despite the absence of install hooks. - **Files touched:** index.js, \_polyfill.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, Windows temp\\analytics\_state, Windows temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_polyfill on every package require., \_polyfill.js runs its downloader immediately at import., \_polyfill.js downloads platform binaries over HTTPS or DNS TXT., \_polyfill.js writes executable payloads to /var/tmp or Windows temp and spawns them detached., lib/telemetry.js contains the same download-to-temp-and-execute profiler mechanism. - **Evidence against:** package.json has no npm lifecycle hooks., No credential-harvesting behavior was confirmed in inspected files. ## Public findings ### 1.
