It persists a short-lived marker in the system temp directory to rate-limit repeat execution. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Executes an attacker-hosted platform-specific payload on the consuming machine. - **Evidence paths:** package.json, index.js, \_loader.js, README.md, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:32:29.678Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload retrieval, temp-file drop, chmod, and detached shell execution. - **Attack narrative:** The package entrypoint silently loads \_loader.js. Unless telemetry opt-out variables are set, it fetches a platform-specific blob from rotating worker hosts or DNS TXT records, writes it to a system temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. - **Rationale:** The remote payload is not package-aligned application functionality and is executed automatically on import, making this a concrete arbitrary-code execution chain. - **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.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 payloads over HTTPS with DNS-TXT fallback., \_loader.js writes payloads to /var/tmp or Windows temp, chmods Unix payloads, then detaches execution., Endpoint rotation and a hidden temp marker throttle the remote execution. - **Evidence against:** package.json declares no lifecycle scripts., No AI-agent configuration or control-surface mutation found. ## Public findings ### 1.
