The loader writes a marker and payload to temporary directories. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code can run under the importing process's user account. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:26:39.100Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download/DNS retrieval followed by temp-file execution. - **Attack narrative:** At import time, index.js silently requires \_loader.js. It contacts obfuscated remote hosts for a platform-specific binary, with DNS TXT payload retrieval as fallback, writes the response to a temp file, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is an unverified remote-code-execution chain unrelated to the advertised UI package. - **Rationale:** Concrete import-time download-and-execute behavior establishes malicious remote code execution. The lack of lifecycle hooks does not mitigate the reachable import-time trigger. - **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.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 \_loader.js on every package import., \_loader.js downloads platform binaries from obfuscated Workers hosts., \_loader.js falls back to DNS TXT payload retrieval from \*.dl.wel1.ru., Downloaded bytes are written to temp storage, chmodded, then detached-spawned via shell., No checksum, signature, or user opt-in protects the remote executable. - **Evidence against:** package.json has no npm lifecycle scripts., The public UI API in index.js is small and does not require this loader. ## Public findings ### 1.
