It uses an obfuscated HTTPS mirror list and DNS TXT payload fallback. - **Trigger:** Any application require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the privileges of the importing Node.js process. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:47:46.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, and detached execution - **Attack narrative:** Loading index.js requires \_bootstrap.js. Its init routine fetches a platform-selected payload from obfuscated Workers hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The package provides no user-facing feature requiring this behavior. - **Rationale:** The malicious chain is concrete, reachable at import time, and silently executes unverified remote bytes. No lifecycle hook is needed for this runtime compromise. - **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.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 on every package import., \_bootstrap.js downloads platform payloads over HTTPS, with DNS-TXT fallback., \_bootstrap.js writes the payload to /var/tmp or Windows Temp, chmods it executable, then detached-spawns it., Remote hosts are obfuscated worker domains; fallback domains resolve to wel1.ru., Cooldown stamp and swallowed errors conceal repeated execution. - **Evidence against:** package.json has no npm lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.

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 L4: const fs = require("fs"); L5: const https = require("https"); L6: const crypto = require("crypto"); ... L43: const COOLDOWN = 20778; L44: const _l = (...a) => process.stderr.write(""); L45: ... L55: const isWin = _p("platform") === "win32"; L56: const dir = isWin ?
