It persists a short-lived temp marker to limit repeat downloads. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary native code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:19:15.414Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, permission change, and detached execution - **Attack narrative:** Requiring index.js loads \_polyfill.js, which immediately runs setup(). It selects a platform payload path, downloads an opaque binary from rotating workers.dev hosts or reconstructs one from DNS TXT records, writes it under a concealed temporary filename, makes it executable on Unix, and starts it detached through a shell. No user action or telemetry configuration is required. - **Rationale:** This is concrete import-time remote payload execution, not legitimate package functionality. The unused telemetry file is additional suspicious material but is unnecessary to establish the attack chain. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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.js on every require., \_polyfill.js downloads platform binaries from four workers.dev hosts., DNS TXT fallback retrieves base64 binary data from \*.dl.wel1.ru., Downloaded bytes are written to a temp path, chmodded, then spawned detached via shell., A temporary marker suppresses repeat execution. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not referenced by the package entrypoint. ## Public findings ### 1.
