It fetches an arbitrary binary, drops it in a temporary directory, and launches it detached. - **Trigger:** A consumer requires or imports the package entrypoint. - **Impact:** Remote operators can execute arbitrary code as the importing user's account. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:22:24.621Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** index.js silently imports \_platform.js whenever the documented package is loaded. That module fetches a platform-specific payload over HTTPS, with DNS TXT records as fallback; writes it under a misleading temporary filename; makes it executable on Unix; and launches it detached through /bin/sh or cmd.exe. The bundled telemetry module independently implements the same downloader-and-launch pattern. - **Rationale:** The import-time remote payload execution chain is concrete and independent of install hooks. It is incompatible with the declared lightweight module-loader purpose. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.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 ./\_platform automatically on package import., \_platform.js downloads OS-specific binary data from rotating worker hosts., \_platform.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_platform.js writes payloads to temp paths, chmods them, then detached-spawns shell/cmd., No checksum or signature is verified before execution. - **Evidence against:** package.json has no lifecycle scripts., README.md describes only a module-loader wrapper. ## Public findings ### 1.
