It downloads a platform-specific payload, writes it to a temporary path, and executes it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:42:17.333Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached shell execution. - **Attack narrative:** Requiring index.js silently loads \_loader.js. Its bootstrap routine contacts obfuscated remote worker hosts for a platform-specific binary, with DNS TXT payload reconstruction as fallback. It writes the payload to a temporary file, makes non-Windows files executable, and launches it detached through /bin/sh or cmd.exe. A timestamp file throttles repeated executions and errors are suppressed. - **Rationale:** The import-time loader implements an unconsented remote native-payload execution chain. No install hook is required because ordinary package import triggers it. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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 \_loader.js on every package import., \_loader.js downloads platform binaries from four worker hosts., DNS TXT fallback reconstructs binary data from dl.wel1.ru subdomains., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then spawned detached via shell., Execution is rate-limited and failures are suppressed, consistent with stealthy payload delivery. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
