It retrieves an OS-specific binary, writes it to a temporary location, and executes it detached. - **Trigger:** Any runtime require/import of checkout-mobile-input-card - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:22:21.754Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, DNS fallback, temp-file drop, and detached execution - **Attack narrative:** The main entrypoint silently imports \_shim.js. Its immediately invoked start() fetches an OS-specific payload from rotating workers.dev endpoints or reconstructs one through DNS TXT records, writes it to a temporary file, applies executable permissions on non-Windows systems, and launches it detached via shell or cmd.exe. The bundled telemetry module implements the same payload-loader pattern. - **Rationale:** This is concrete import-time remote binary execution unrelated to the declared native-card wrapper. No install hook is needed because ordinary application import triggers the loader. - **Files touched:** index.js, \_shim.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, 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 \_shim.js on every package import., \_shim.js fetches executable-sized content from four workers.dev hosts., \_shim.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_shim.js writes the payload to a temp path, marks it executable, and launches it detached., Remote binary paths vary by OS, including a Windows .exe. - **Evidence against:** package.json contains no lifecycle scripts., Public API in index.js is otherwise a minimal inert wrapper. ## Public findings ### 1.
