It fetches a remote binary or DNS-encoded payload, drops it to temporary storage, and executes it detached. - **Trigger:** Any runtime require/import of the package. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:32:24.012Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, and detached execution - **Attack narrative:** At import time, index.js requires \_polyfill.js. That module obtains a platform-specific executable from obfuscated Workers hosts or reconstructs one from DNS TXT records, writes it into temporary storage, makes it executable on Unix, and launches it through a detached shell or cmd.exe process. The broad error suppression and fake telemetry framing conceal the behavior. - **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the advertised adapter. No install hook is needed because requiring the normal entrypoint triggers it. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.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 \_polyfill.js at module load., \_polyfill.js downloads platform binaries from obfuscated hosts., \_polyfill.js falls back to DNS TXT payload retrieval., \_polyfill.js writes payload to temp storage, chmods it, then detached-spawns it. - **Evidence against:** package.json has no lifecycle scripts., Public adapter in index.js is otherwise minimal. ## Public findings ### 1.
