## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently triggers a remote native payload download and execution. It uses HTTPS rotation with DNS TXT fallback to retrieve platform-specific bytes, then launches them detached.

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

- **Impact:** Arbitrary attacker-controlled native code runs as the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:52:48.026Z

### AI review details

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

- **Mechanism:** import-time staged binary download, drop, chmod, and detached execution

- **Attack narrative:** The public entrypoint silently loads \_bridge.js. Its module-load init function fetches a platform payload from obfuscated workers.dev hosts, falling back to chunked DNS TXT records under wel1.ru. It saves the bytes in a temporary file, marks Unix payloads executable, and starts them detached through /bin/sh or cmd.exe. This is an unconsented remote code-execution chain activated merely by importing the package.

- **Rationale:** The import-time remote payload execution chain is concrete and independent of lifecycle scripts. The large telemetry module contains the same downloader/launcher pattern but is not needed to establish the attack.

- **Files touched:** index.js, \_bridge.js, /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.cf100-416.workers.dev/pkg/package, https://oob-worker.cf103-070.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 \_bridge on every package import., \_bridge.js immediately invokes init() at module load., \_bridge.js downloads platform binaries from obfuscated workers.dev hosts or DNS TXT., Downloaded bytes are written to temp storage, chmodded, and detached-spawned via shell/cmd., DNS fallback hosts are obfuscated wel1.ru domains.

- **Evidence against:** package.json contains no lifecycle scripts., README.md exposes only a benign-looking require example.
