## Security analysis

### Published attack-surface review

- **Summary:** Importing the package triggers an unprompted remote binary downloader and launcher. It uses rotating HTTPS hosts with DNS-TXT payload fallback, then executes the payload from temporary storage.

- **Trigger:** Any runtime require/import of the package.

- **Impact:** Arbitrary attacker-controlled native code execution under the importing process user.

- **Evidence paths:** index.js, \_polyfill.js, lib/telemetry.js, package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T21:53:01.581Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** import-time remote payload download, temporary-file drop, chmod, and detached shell execution

- **Attack narrative:** Requiring index.js silently loads \_polyfill.js. Its main routine obtains a platform-specific executable from obfuscated workers.dev hosts or DNS TXT records under wel1.ru domains, writes it to a temporary path, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe.

- **Rationale:** This is concrete import-time remote payload execution, unrelated to the declared native-bridge API. Lack of an npm lifecycle hook does not mitigate execution on ordinary package import.

- **Files touched:** \_polyfill.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\<random\>.exe

- **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.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 \_polyfill.js automatically on package require., \_polyfill.js downloads platform binaries over HTTPS or DNS TXT., \_polyfill.js writes, chmods, and detached-spawns the downloaded binary., Remote hosts and domains are obfuscated through string concatenation., lib/telemetry.js contains the same downloader/launcher capability.

- **Evidence against:** package.json has no lifecycle scripts., The public index API is otherwise a minimal inert bridge.
