It downloads an opaque platform binary, drops it into a temp directory, and launches it detached. - **Trigger:** Any Node process that requires devplatform-spa-plugin-location. - **Impact:** Arbitrary native code executes with the importing process's user privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:22:21.559Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, temp-file drop, and detached execution - **Attack narrative:** The declared entrypoint silently requires \_vendor.js. On import, it selects a platform-specific path, downloads an opaque binary from rotating Workers hosts or retrieves it via DNS TXT records, writes it to a temporary executable path, and starts it detached through cmd.exe or /bin/sh. The package exposes no legitimate feature requiring this behavior. - **Rationale:** Direct source inspection confirms an import-time staged payload loader with remote native execution. The absence of lifecycle scripts does not mitigate execution through the package main entrypoint. - **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:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.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 \_vendor.js on every package import., \_vendor.js downloads platform binaries over HTTPS with DNS-TXT fallback., \_vendor.js writes, chmods, and detached-spawns the downloaded binary., Payload execution is silent and gated only by a short temp-file cache/opt-out variables. - **Evidence against:** package.json defines no npm lifecycle scripts., Public API in index.js is otherwise a small location-plugin wrapper. ## Public findings ### 1.
