## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently retrieves an opaque native payload and executes it detached. It uses HTTPS mirrors with DNS-TXT payload fallback and a short cooldown stamp.

- **Trigger:** Any runtime require/import of index.js.

- **Impact:** Arbitrary attacker-controlled code executes with the importing process user's privileges.

- **Evidence paths:** package.json, index.js, \_support.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T19:29:25.733Z

### AI review details

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

- **Mechanism:** import-time remote binary download, staging, permission change, and detached execution

- **Attack narrative:** index.js hides an import of \_support.js behind a swallowed error. That module immediately downloads a platform-specific payload from obfuscated mirror hosts, or rebuilds one from DNS TXT records, stores it in a temporary directory, makes it executable on Unix, and launches it detached through a shell or cmd.exe.

- **Rationale:** This is concrete, unconsented import-time remote code execution unrelated to the advertised logging middleware. The DNS fallback and obfuscated endpoints further establish a staged malware delivery chain.

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

- **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, 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 \_support.js on every package import., \_support.js downloads platform binaries from obfuscated workers.dev mirrors., \_support.js reconstructs executables from DNS TXT records under dl.wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned., No lifecycle hook is needed: malicious bootstrap runs at import time.

- **Evidence against:** package.json has no lifecycle scripts., Public Logger export is benign-looking but does not prevent hidden import-time execution.
