It downloads an executable from obfuscated endpoints or DNS TXT records, drops it to a temporary directory, and starts it detached. - **Trigger:** Any runtime require/import of devplatform-rest-client, via index.js. - **Impact:** Arbitrary attacker-supplied native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:30:18.547Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** The main entrypoint suppresses errors while importing \_init.js. That module immediately fetches a platform-specific payload from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records, stores it in a temporary path, makes non-Windows files executable, and launches it detached through cmd.exe or /bin/sh. - **Rationale:** This is an import-time remote payload execution chain unrelated to the tiny advertised REST-client API. Its obfuscation, DNS fallback, hidden temp staging, and detached execution establish concrete malware behavior. - **Files touched:** index.js, \_init.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/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, 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 platform-specific binary payloads from three workers.dev hosts., \_init.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written under /var/tmp or Windows Temp, chmodded, then detached-spawned via shell., No lifecycle hook is needed: requiring the declared main entry starts this chain. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint; its configurable telemetry API is not the trigger. ## Public findings ### 1.
