It persists only a short-lived timestamp marker and payload file in temp directories. - **Trigger:** Runtime import/require of devplatform-nx-spa - **Impact:** Arbitrary remote code execution in the importing user's context. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:47:26.921Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded platform payload written to temp storage and detached-executed - **Attack narrative:** Requiring index.js immediately loads \_support.js. That module fetches an OS-specific payload from obfuscated workers.dev mirrors, falling back to DNS TXT chunks from wel1.ru domains. It writes the response to a temporary executable path, marks it executable on Unix, and launches it detached via /bin/sh or cmd.exe. - **Rationale:** Source confirms an import-time remote payload download-and-execute chain, not ordinary telemetry. The absence of lifecycle hooks does not mitigate runtime RCE on package import. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 ./\_support at package import time., \_support.js downloads platform payloads from worker hosts or DNS TXT., \_support.js writes payloads to /var/tmp or Windows Temp, chmods, then detached-spawns them., Endpoints are obfuscated and include multiple workers.dev mirrors plus wel1.ru DNS domains. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration writes were found. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_support.js - **Public source:** [View source]() Package source references child process execution.

L93: try { L94: require("dns").resolveTxt(d, (e, rr) => { L95: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_support.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 -> _support.js L6: const path = require("path"); L7: const https = require("https"); L8: ...
