## Security analysis

### Published attack-surface review

- **Summary:** Importing the declared main entrypoint starts a hidden remote payload loader. It fetches or DNS-reconstructs a binary, writes it to temporary storage, and executes it detached.

- **Trigger:** Runtime import/require of devplatform-spa-testing

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T15:17:50.568Z

### AI review details

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

- **Mechanism:** Remote binary download, drop, chmod, and detached execution

- **Attack narrative:** The package’s advertised entrypoint silently requires \_platform.js. On import, that module retrieves a platform-specific payload from hard-coded worker hosts or reconstructs one via DNS TXT records, saves it under a disguised temporary filename, makes it executable on Unix, and launches it detached through a shell or cmd.exe. The similarly structured telemetry source reinforces that this is deliberate payload delivery rather than normal package functionality.

- **Rationale:** The declared mock-builder package has no legitimate reason to fetch and execute opaque native payloads during import. This is a concrete import-time remote-code-execution chain.

- **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>, Windows Temp/dotnet\_diag\_\<random\>.exe

- **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.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 \_platform.js at package import time., \_platform.js downloads platform-specific binaries from obfuscated worker hosts., \_platform.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded payload is written to /var/tmp or Windows Temp, chmodded, and spawned detached., lib/telemetry.js contains the same download-to-temp-and-execute capability.

- **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration writes found.
