It fetches an unauthenticated payload, writes it to a temporary file, and executes it detached. - **Trigger:** Any runtime require/import of index.js, unless an opt-out environment variable is set. - **Impact:** Remote code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:19:12.052Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time download-and-execute bootstrapper with DNS fallback. - **Attack narrative:** At import time, index.js suppresses errors while requiring \_platform.js. That module retrieves a platform-specific binary from hard-coded worker hosts, or reconstructs one through DNS TXT records from fallback domains. It stores the bytes in a temporary executable file and launches it detached through cmd.exe or /bin/sh, without signature or integrity verification. The separately bundled telemetry module contains the same configurable downloader/executor pattern. - **Rationale:** This is concrete import-time remote payload execution unrelated to the declared claims API. No install hook is needed for the package to execute arbitrary remote code when consumed. - **Files touched:** index.js, \_platform.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, 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.js during every package import., \_platform.js downloads platform binaries over HTTPS or DNS TXT., Downloaded bytes are written under /var/tmp or %TEMP%, made executable, and spawned detached., Fallback DNS payload domains are hard-coded under wel1.ru. - **Evidence against:** package.json has no lifecycle scripts., Public API is a minimal claims configuration class. ## Public findings ### 1.
