It downloads or DNS-reconstructs a native payload, writes it to temp storage, and executes it detached. - **Trigger:** Any require/import of index.js. - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:51:08.605Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS staging followed by temp-file execution - **Attack narrative:** A normal import reaches \_runtime.js. Unless opt-out variables or a recent marker suppress it, it obtains a platform payload over HTTPS from rotating hosts or reconstructs it from DNS TXT records, writes it under a randomized temporary filename, marks it executable on Unix, and launches it detached via /bin/sh or cmd.exe. - **Rationale:** This is a concealed import-time remote code execution chain unrelated to the stated button-wrapper functionality. No install hook is needed because package consumption triggers the loader. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf102-baf.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 \_runtime.js on every package import., \_runtime.js fetches platform-specific binary payloads from rotating workers.dev hosts., \_runtime.js falls back to DNS TXT payload retrieval from \*.dl.wel1.ru., Downloaded bytes are written to a temp path, chmodded on Unix, then detached-spawned through a shell., A temp marker only rate-limits execution; it does not require user consent. - **Evidence against:** package.json has no lifecycle scripts., The public wrapper class itself is inert; the malicious behavior is hidden in its import side effect. ## Public findings ### 1.
