It uses HTTPS hosts with DNS TXT fallback and drops a platform-specific payload to temporary storage. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:59:49.371Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, drop, chmod, and detached execution - **Attack narrative:** Requiring the declared main entrypoint loads \_init.js, which immediately invokes setup(). Unless opt-out environment variables or a short-lived marker prevent it, setup downloads a payload from rotating HTTPS endpoints, falling back to DNS TXT chunks. It writes the payload into a temporary directory, makes non-Windows files executable, and launches it detached via cmd.exe or /bin/sh. - **Rationale:** This is a concrete, automatic remote-code-execution chain in the package import path. The lack of an npm lifecycle hook does not mitigate the unconsented runtime payload execution. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.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 \_init.js on every package import., \_init.js downloads platform payloads from rotating workers.dev hosts or DNS TXT., \_init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it., The download/execute chain is automatic and has no user invocation requirement. - **Evidence against:** package.json has no lifecycle scripts., Public Retriever API is otherwise minimal; lib/telemetry.js is not imported by the entrypoint. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_init.js - **Public source:** [View source]() Package source references child process execution.
