It obtains a platform-specific binary, writes it to temporary storage, makes it executable on Unix, and launches it detached. - **Trigger:** Runtime require/import of index.js - **Impact:** Unconsented arbitrary native code execution under the importing process's user. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:55:48.218Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file drop, and detached shell execution - **Attack narrative:** The advertised entrypoint silently requires \_vendor.js. Its import-time init fetches a binary for the host platform from obfuscated worker hosts, falls back to DNS TXT payload retrieval, writes the result to a temporary path, chmods it on Unix, and starts it through a detached shell or cmd.exe process. This is a direct staged remote-code-execution chain unrelated to the documented adapter API. - **Rationale:** Source inspection confirms an import-triggered downloader and detached execution path; no lifecycle hook is needed for the malicious behavior. The telemetry file duplicates the same binary-extension pattern but is not required to establish the attack. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 \_vendor.js on every package import., \_vendor.js downloads platform binaries over HTTPS and DNS TXT., Downloaded bytes are written to a temp executable and launched detached., Payload hosts are obfuscated and randomly rotated., A cooldown stamp limits repeated execution and errors are suppressed. - **Evidence against:** package.json has no lifecycle scripts., The public adapter class itself is inert. ## Public findings ### 1.
