It fetches opaque bytes, writes an executable temporary file, and launches it detached. - **Trigger:** Runtime import of index.js - **Impact:** Arbitrary attacker-controlled code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, \_loader.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:12:11.886Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached shell execution - **Attack narrative:** At package import, index.js requires \_loader.js. Its bootstrap fetches a platform-specific opaque payload from obfuscated external hosts, or reconstructs one from DNS TXT records. It writes the bytes to a temporary executable path, applies execute permission on non-Windows systems, then starts it through a detached shell or cmd.exe process. This creates silent remote code execution without user invocation or payload integrity verification. - **Rationale:** The import-time loader is concrete remote payload execution, not package-aligned API behavior. Telemetry code independently contains the same download-and-launch primitive. - **Files touched:** index.js, \_loader.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.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 \_loader.js on every package import., \_loader.js downloads platform payloads from three obfuscated worker hosts., \_loader.js falls back to DNS TXT payload retrieval via \*.wel1.ru., Downloaded bytes are written under /var/tmp or Windows Temp, chmodded, and launched detached., No hash/signature validation is performed before execution. - **Evidence against:** package.json has no lifecycle scripts., The declared API entry point is otherwise a minimal adapter class. ## Public findings ### 1.
