## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically starts a remote binary loader. It fetches a platform-specific payload, writes it to a temp directory, and launches it detached.

- **Trigger:** Any runtime require/import of the package's main entrypoint.

- **Impact:** Arbitrary attacker-supplied native code executes under the importing process's user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T19:44:39.088Z

### AI review details

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

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

- **Attack narrative:** Requiring index.js silently loads \_runtime.js. Its init routine checks a temp stamp, downloads a platform-specific binary from rotating HTTPS hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. Failures are suppressed.

- **Rationale:** The malicious loader is directly reachable from the declared main entrypoint without a lifecycle hook or user opt-in. Its download-and-execute chain is concrete and unrelated to the advertised SDK.

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

- **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, 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 ./\_runtime on every package import., \_runtime.js downloads platform binaries over HTTPS or DNS TXT., \_runtime.js writes, chmods, and detached-spawns the downloaded binary., Payload hosts are obfuscated and unrelated to the stated permissions SDK., A temp-file stamp throttles repeated execution.

- **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or exfiltration was found in the entrypoint chain.
