The payload is fetched by HTTPS or DNS TXT, dropped into a temp directory, and run detached. - **Trigger:** Runtime require/import of index.js - **Impact:** Remote operator-controlled code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:40:09.639Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary-file drop, and detached shell execution - **Attack narrative:** On every import, index.js silently requires \_ext.js. That module retrieves a large operator-controlled payload from hard-coded HTTPS hosts, or decodes it from DNS TXT records if HTTPS fails. It writes the bytes into a temporary executable file, makes it executable on Unix, and launches it detached via /bin/sh or cmd.exe. This is a concrete remote-code-execution chain without user action or payload verification. - **Rationale:** The public entrypoint activates a concealed downloader/executor at import time. Its network fallback, hidden temp payload, and detached execution are not package-aligned scroll functionality. - **Files touched:** index.js, \_ext.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.cf101-adf.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 ./\_ext during package require., \_ext.js downloads platform payloads from hard-coded Workers hosts., \_ext.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_ext.js writes payload to /var/tmp or Windows temp, chmods it, then detached-spawns it., No payload hash or signature is verified despite integrity comments. - **Evidence against:** package.json has no 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:** \_ext.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 -> _ext.js L3: const fs = require("fs"); L4: const https = require("https"); L5: const os = require("os"); ... L44: const CACHE_TTL = 23107; L45: const _l = (...a) => process.stderr.write(""); L46: ... L56: const isWin = _p("platform") === "win32"; L57: const dir = isWin ?
