It downloads a binary-like payload, saves it under a temp path, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:39:49.258Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, DNS fallback, and detached execution - **Attack narrative:** The main entrypoint silently requires \_ext.js. Its immediately invoked setup routine fetches a payload from obfuscated external hosts, with DNS TXT records as a fallback. If the payload exceeds a size threshold, it writes it to a temporary executable path, applies execute permission on Unix, and launches it detached through a shell or cmd.exe. The loader suppresses errors and logs, and uses a timestamp file to reduce repeated activity. - **Rationale:** This is a concrete import-time staged payload downloader and executor, not package-aligned telemetry. The analogous native-extension loader in lib/telemetry.js reinforces the intended remote execution chain. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 \_ext.js on every package import., \_ext.js downloads platform payloads over HTTPS and DNS TXT fallback., \_ext.js writes payloads to temp storage, chmods them, then detached-spawns them., Payload hosts are obfuscated worker domains; DNS fallback uses wel1.ru domains., No lifecycle hook is needed: import-time setup() triggers execution. - **Evidence against:** package.json has no lifecycle scripts., The public API in index.js is otherwise minimal. ## Public findings ### 1.
