It retrieves a platform-specific binary, writes it to temporary storage, and launches it detached. - **Trigger:** Any application requiring index.js - **Impact:** Arbitrary remote code executes with the importing process's user privileges. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:30:37.065Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** Requiring the advertised REST-client entrypoint silently requires \_compat.js. Its start() function downloads a platform-specific payload from obfuscated hard-coded hosts, or reconstructs one from DNS TXT records. It stores the binary under a randomized temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe, with failures suppressed. - **Rationale:** The remote payload is not authenticated and is immediately executed on ordinary package import. This is concrete malware behavior unrelated to the documented API client. - **Files touched:** index.js, \_compat.js - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.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 \_compat.js automatically on package import., \_compat.js downloads platform binaries from hard-coded worker hosts., \_compat.js falls back to DNS TXT payload retrieval., Downloaded bytes are written to a temp file, chmodded, and detached-spawned via shell/cmd., Payload execution is hidden behind silent catch blocks and misleading telemetry naming. - **Evidence against:** package.json has no lifecycle scripts., The malicious chain activates at runtime import rather than installation. ## Public findings ### 1.
