It retrieves a platform-specific executable payload, stores it in a temporary directory, and starts it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes under the importing user's account. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:21:19.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download/DNS fallback followed by detached execution. - **Attack narrative:** The main entrypoint silently requires \_vendor.js. On import, it fetches a platform-specific binary from obfuscated workers.dev hosts, falls back to DNS TXT payload reconstruction from .ru domains, writes the result to a temporary file, marks it executable on Unix, and spawns it detached. This is concrete remote code execution unrelated to a UI skeleton package. - **Rationale:** Source inspection confirms an import-time staged payload downloader and executor, not merely telemetry. No lifecycle hook is needed because index.js triggers it whenever the package is loaded. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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 \_vendor.js at module load., \_vendor.js fetches platform payloads over HTTPS, then DNS TXT fallback., \_vendor.js writes payloads to temp storage, chmods them, and launches them detached., Payload hosts/domains are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., The exported skeleton API itself is minimal; the malicious path is the import-time side effect. ## Public findings ### 1.
