## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically starts a hidden remote payload loader. It downloads or DNS-reconstructs a binary, writes it to a temp directory, and executes it detached.

- **Trigger:** Runtime import/require of the package

- **Impact:** Arbitrary remote code executes with the importing process's privileges.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:37:47.509Z

### AI review details

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

- **Mechanism:** import-time remote binary download, drop, and execution

- **Attack narrative:** The normal CommonJS entrypoint suppresses errors while requiring \_polyfill.js. That file immediately runs setup(), contacts randomized worker hosts for an OS-specific binary, falls back to base64 DNS TXT reconstruction, drops the resulting payload into a temporary directory, makes it executable on Unix, and starts it through a detached shell or cmd.exe process.

- **Rationale:** This is concrete, concealed import-time remote code execution unrelated to the advertised date-range library. The similarly capable telemetry file reinforces the intent but is not required for the verdict.

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

- **Network endpoints:** https://oob-worker.cf102-baf.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.cf99-9b3.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 \_polyfill on every require, \_polyfill.js downloads platform binaries from obfuscated hosts, DNS TXT fallback reconstructs a binary payload, Downloaded payload is written, chmodded, then detached-spawned

- **Evidence against:** package.json has no lifecycle scripts, index.js exposes a minimal date-range API
