It downloads or DNS-reconstructs a platform payload, stores it in a temp directory, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T18:08:31.118Z - **Finished:** 2026-08-05T18:09:19.836Z - **Download time:** 503 ms - **Static scan time:** 33 ms - **AI review time:** 48181 ms - **Total time:** 48718 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package activates a concealed remote binary loader. It downloads or DNS-reconstructs a platform payload, stores it in a temp directory, and launches it detached. - **Trigger:** Any runtime import/require of index.js. - **Impact:** Unconsented arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:09:19.836Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temp-file drop, and detached execution - **Attack narrative:** The public entrypoint silently requires \_ext.js. Its main routine fetches a binary from obfuscated worker hosts, or reconstructs one from DNS TXT records, writes it to a temporary executable path, then starts it detached via cmd.exe or /bin/sh. The state file merely throttles repeat execution and does not provide user consent or payload validation. - **Rationale:** This is an import-time staged remote-code-execution loader unrelated to the declared UI-component package. The absent lifecycle hook does not mitigate automatic execution when consumers import it. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 \_ext.js on every package import., \_ext.js downloads platform binaries over HTTPS., \_ext.js falls back to DNS TXT payload retrieval., \_ext.js writes payload to /var/tmp or temp and executes it detached., No integrity/signature verification is performed. - **Evidence against:** package.json has no lifecycle scripts., The advertised index.js API is otherwise a minimal component wrapper. ## Public findings ### 1.
