It fetches an opaque platform-specific payload, writes it to temporary storage, then executes it detached. - **Trigger:** Any require/import of the main index.js entry point. - **Impact:** Arbitrary remote code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_compat.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:32:35.164Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download/DNS retrieval followed by detached native execution - **Attack narrative:** Loading index.js imports \_compat.js. Its bootstrap fetches an opaque binary from rotating workers.dev hosts or reconstructs one from DNS TXT records, stores it in a temporary location, makes Unix payloads executable, and starts it detached via a shell or cmd.exe. This is an undisclosed remote-code loader activated at import time. - **Rationale:** The source implements concrete, undisclosed remote binary retrieval and execution on import. The absence of lifecycle hooks does not mitigate this reachable runtime execution chain. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js unconditionally imports \_compat.js on package load., \_compat.js downloads platform payloads from workers.dev hosts., \_compat.js falls back to DNS TXT payload retrieval from well1.site domains., \_compat.js writes a hidden/temp executable, chmods it, and launches it detached., README.md describes only an event handler; it does not disclose this behavior. - **Evidence against:** package.json has no lifecycle scripts., No credential collection or AI-agent configuration mutation was found. ## Public findings ### 1.
