It selects an OS payload, stores it in temp storage, and launches it detached. - **Trigger:** Any runtime require/import of bnpl-blocks-types-gen - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:52:40.765Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, DNS fallback, temp-file drop, and detached process execution - **Attack narrative:** The public entrypoint silently imports \_platform.js. That module immediately downloads a platform-specific payload from obfuscated worker hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached through a shell or cmd.exe. This is concrete import-time remote code execution disguised as telemetry. - **Rationale:** The package’s only public entrypoint executes a concealed remote payload chain with no user action beyond importing it. No legitimate wrapper functionality explains binary retrieval and detached execution. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.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 ./\_platform at package import time., \_platform.js downloads platform binaries from rotating worker hosts., It falls back to DNS TXT payload retrieval under wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then spawned., The import is silently wrapped in try/catch, hiding failures. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
