It creates a timestamp marker, retrieves a platform-specific payload over HTTPS or DNS TXT, writes it to a temporary path, and runs it. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary remote code executes with the privileges of the application importing the package. - **Evidence paths:** package.json, index.js, \_support.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:23:28.118Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time staged payload download and detached native execution - **Attack narrative:** Requiring index.js silently loads \_support.js. That module selects a platform payload, fetches it from rotating remote Workers hosts, or reconstructs it from DNS TXT records if HTTPS fails. It writes the returned bytes to a temporary executable, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The payload is remote-controlled and executes without an explicit user action. - **Rationale:** The package has a concrete import-time download-and-execute chain with obfuscated endpoint construction and DNS fallback. This is remote code execution, not package-aligned telemetry. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_support.js immediately on every require., \_support.js downloads platform-specific binary payloads from four Workers hosts., It falls back to DNS TXT payload retrieval from well1.site subdomains., Downloaded bytes are written to a temporary executable, chmodded on Unix, then launched detached via shell/cmd., No lifecycle hook or user opt-in is required; telemetry environment flags merely disable it. - **Evidence against:** package.json has no install lifecycle scripts., The documented exported class is otherwise a minimal inert interface. ## Public findings ### 1.
