It uses rotating HTTPS mirrors with DNS TXT payload fallback. - **Trigger:** Any runtime require/import of checkout-mobile-input-email. - **Impact:** Arbitrary native code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_helpers.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:22:23.791Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, drop, chmod, and detached execution - **Attack narrative:** At module import, index.js silently loads \_helpers.js. Its bootstrap contacts obfuscated Workers hosts for a platform-specific binary, then falls back to reconstructing a base64 payload from DNS TXT records. A payload over 1000 bytes is written to a temporary file, made executable on Unix, and launched detached through a shell or cmd.exe. - **Rationale:** The package has concrete import-time remote binary execution unrelated to its advertised mobile-input API. The same payload-loader capability is duplicated in the unexported telemetry source. - **Files touched:** index.js, \_helpers.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 \_helpers.js on every package import., \_helpers.js downloads platform binaries over HTTPS or DNS TXT., \_helpers.js writes, chmods, and detached-spawns the downloaded payload., Remote hosts are obfuscated by string concatenation; fallback DNS payload delivery is supported., No checksum, signature, or user action guards remote binary execution. - **Evidence against:** package.json has no lifecycle scripts., The public API in index.js is otherwise minimal. ## Public findings ### 1.
