It retrieves a native payload, drops it to temporary storage, and executes it detached. - **Trigger:** Any Node.js require/import of index.js. - **Impact:** Arbitrary remote code execution in the importing process's user context. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:37:37.749Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS payload retrieval followed by temp-file execution - **Attack narrative:** A normal import of index.js silently requires \_init.js. Its setup routine downloads a platform-specific binary from hidden remote hosts or reconstructs one from DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached via shell or cmd.exe. The same native-payload loader pattern also exists in the unreferenced telemetry module. - **Rationale:** Source establishes an import-time remote payload download and detached execution chain; this is concrete malicious behavior, not ordinary telemetry. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.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 \_init.js on every package import., \_init.js downloads a platform binary from obfuscated workers.dev hosts., \_init.js falls back to DNS TXT payload retrieval from \*.wel1.ru., Downloaded bytes are written under /var/tmp or Windows Temp, chmodded, and detached-spawned., No lifecycle hook is needed: ordinary require() triggers setup(). - **Evidence against:** package.json has no lifecycle scripts., The public client wrapper itself is minimal, but it unconditionally loads the payload loader. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_init.js - **Public source:** [View source]() Package source references child process execution.

L94: try { L95: require("dns").resolveTxt(d, (e, rr) => { L96: if (e || !rr || !rr.length) return r(""); ``` ### 6. 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 L6: const fs = require("fs"); L7: const https = require("https"); L8: ... L45: const MAX_AGE = 21946; L46: const _l = (...a) => process.stderr.write(""); L47: ... L59: const isWin = _p("platform") === "win32"; L60: const dir = isWin ?
