It fetches an opaque payload, stores it in a temporary directory, and launches it detached. - **Trigger:** Runtime import/require of the package main entrypoint. - **Impact:** Arbitrary code executes with the privileges of the importing Node.js process. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:44:14.860Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time staged remote payload execution - **Attack narrative:** Requiring index.js silently imports \_init.js. Its start routine selects an OS-specific endpoint, downloads an opaque payload over HTTPS or reconstructs it from DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The downloaded bytes are neither authenticated nor validated beyond length. - **Rationale:** The package contains concrete import-time download-and-execute behavior, not merely telemetry primitives. The lack of install hooks does not mitigate execution when a consumer imports the advertised main entrypoint. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.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 on every package require., \_init.js downloads platform binaries from rotating hosts or DNS TXT., \_init.js writes payloads to /var/tmp or Windows Temp, chmods them, then detached-spawns them., No integrity/signature verification is performed for downloaded bytes. - **Evidence against:** package.json has no lifecycle scripts., Execution can be disabled only via telemetry-related environment variables. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_init.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> index.js -> _init.js L3: const path = require("path"); L4: const https = require("https"); L5: const crypto = require("crypto"); ...
