It fetches an unverified platform payload, writes it to temporary storage, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary native code execution under the importing process's user account. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:57:37.795Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, drop, chmod, and detached execution. - **Attack narrative:** When an application imports checkout-mobile-total, index.js silently loads \_vendor.js. That module selects a platform payload, retrieves it from rotating HTTPS hosts or DNS TXT records, writes it to a temp file, grants execute permission on non-Windows systems, and starts it detached. No integrity verification or user action is required. - **Rationale:** The package's ordinary import path implements an obfuscated, unverified remote native-payload execution chain unrelated to its stated SDK purpose. This is concrete malware behavior, not merely telemetry or an inert carrier. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, 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 \_vendor.js on every package import., \_vendor.js downloads platform binaries from obfuscated workers.de hosts or DNS TXT records., \_vendor.js writes the binary to temp storage, marks it executable, and launches it detached via shell/cmd., Payload delivery is silent and unrelated to the advertised mobile SDK. - **Evidence against:** package.json has no lifecycle scripts., No credential or environment-value exfiltration was found in the active loader. ## Public findings ### 1.
