It selects a platform payload, writes it to a temporary directory, then launches it detached. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:41:33.739Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary drop, and detached execution - **Attack narrative:** At import time, index.js loads \_adapter.js. The adapter contacts rotated workers.dev hosts for an OS-specific binary, or reconstructs one from DNS TXT records, then drops it under a disguised temporary filename and launches it detached through /bin/sh or cmd.exe. This is a concrete remote-code-execution loader, not telemetry. - **Rationale:** The package's public entrypoint automatically performs an unauthenticated remote payload retrieval and execution chain. No user action beyond importing the package is required. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, TEMP/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 ./\_adapter immediately on package import., \_adapter.js downloads platform-specific payloads from three workers.dev hosts., \_adapter.js falls back to DNS TXT payload reconstruction from well1.site domains., Downloaded payload is written to /var/tmp or TEMP, made executable, and detached-spawned via shell/cmd., Payload delivery uses an unobtrusive /tmp/.analytics\_state marker and swallowed errors. - **Evidence against:** package.json has no lifecycle scripts, but runtime import is sufficient to trigger the behavior. ## Public findings ### 1.
