## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently starts a remote binary downloader. It can retrieve a binary over HTTPS or DNS TXT, save it to temporary storage, and execute it detached.

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

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:45:15.831Z

### AI review details

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

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

- **Attack narrative:** A normal import reaches \_bridge.js without user opt-in. The bridge selects a platform payload, downloads it from obfuscated workers.dev hosts or reconstructs it from DNS TXT records, writes it into temporary storage, sets execute permission on non-Windows systems, then launches it through a detached shell or cmd.exe process.

- **Rationale:** This is a concrete import-time remote-code-execution chain, not telemetry: it retrieves opaque binaries and executes them silently. The absence of lifecycle hooks does not mitigate runtime import execution.

- **Files touched:** index.js, \_bridge.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>

- **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.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 \_bridge on every package import., \_bridge.js downloads platform binaries from four obfuscated workers.dev hosts., \_bridge.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_bridge.js writes payloads to /var/tmp or Windows temp, marks executable, and detached-spawns them., lib/telemetry.js contains a duplicate configurable download-to-execute loader.

- **Evidence against:** package.json has no lifecycle scripts., No source evidence of credential collection before payload execution.
