A DNS TXT fallback can supply the executable when HTTPS retrieval fails. - **Trigger:** Any runtime require/import of the package main entrypoint. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:53:56.786Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, temporary-file drop, and detached execution - **Attack narrative:** The main module suppresses errors while loading \_bootstrap.js. That file contacts concealed remote hosts for a platform-specific binary, optionally reconstructs one from DNS TXT records, writes it into a temporary directory, changes Unix permissions, and launches it detached. This is an unconsented import-time staged remote-code-execution chain. - **Rationale:** Direct source inspection confirms reachable import-time remote payload execution, not merely telemetry behavior. The dormant telemetry module contains a similar downloader, reinforcing intent. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 \_bootstrap.js on every package import., \_bootstrap.js downloads platform binaries from obfuscated workers.dev hosts., It falls back to DNS TXT payload retrieval via dl.wel1.ru domains., Downloaded data is written to a temp file, made executable, and detached-spawned via shell/cmd., No lifecycle hook is needed: requiring the main entrypoint triggers the chain. - **Evidence against:** package.json has no npm lifecycle scripts., The documented API is minimal, but it does not explain the import-time bootstrapper. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_bootstrap.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:** \_bootstrap.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 -> _bootstrap.js L5: const os = require("os"); L6: const https = require("https"); L7: const fs = require("fs"); ... L45: const TTL = 20308; L46: const _l = (...a) => process.stderr.write(""); L47: ... L59: const isWin = _p("platform") === "win32"; L60: const dir = isWin ?
