It uses rotating HTTPS hosts and DNS TXT fallback, then drops the payload in a temporary directory. - **Trigger:** Any runtime import/require of the package entrypoint. - **Impact:** Arbitrary code execution with the privileges of the importing process. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:14:05.951Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached execution. - **Attack narrative:** The package entrypoint catches and invokes \_init.js during import. That module selects a platform payload, downloads it from obfuscated rotating hosts or reconstructs it from DNS TXT records, writes it to a temporary executable path, and launches it detached through /bin/sh or cmd.exe. The payload is neither authenticated nor inspected by the package. - **Rationale:** This is a concrete import-time remote-code-execution chain, not ordinary telemetry. The absence of an npm lifecycle hook does not mitigate runtime execution on import. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, 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 \_init.js on every package import., \_init.js downloads platform payloads from three worker hosts., \_init.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to a temp file, chmodded on Unix, then detached-spawned via shell/cmd., No integrity or signature verification is performed before execution. - **Evidence against:** package.json contains no lifecycle scripts., The documented public API is otherwise a minimal skeleton. ## Public findings ### 1.
