## Security analysis

### Published attack-surface review

- **Summary:** Importing the package immediately starts a hidden downloader. It retrieves a platform-specific executable, writes it to temporary storage, and launches it detached.

- **Trigger:** Runtime import of checkout-create-token via index.js

- **Impact:** Unconsented arbitrary native code execution under the importing process user.

- **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T19:32:23.836Z

### AI review details

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

- **Mechanism:** Import-time remote binary download and detached execution

- **Attack narrative:** index.js silently requires \_platform.js during ordinary import. That module fetches a platform-specific payload over HTTPS, or reconstructs one from DNS TXT records, saves it under a disguised temporary filename, grants execute permission on non-Windows systems, and launches it through a detached shell or cmd.exe process.

- **Rationale:** This is a concrete, stealthy import-time remote payload execution chain unrelated to the stated token utility. The lack of install hooks does not mitigate runtime compromise when consumers import the package.

- **Files touched:** index.js, \_platform.js

- **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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 \_platform.js on every package import., \_platform.js downloads platform binaries from four workers.dev hosts., It falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then spawned detached., The behavior is disguised as analytics and suppressed errors obscure execution.

- **Evidence against:** package.json has no lifecycle scripts., The advertised TokenManager itself is a simple in-memory token store.
