## Verdict summary
**Blocked & quarantined** — Arbitrary native code execution under the importing process user.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 35.7.1
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The import-time loader implements an unconsented remote native-payload execution chain. No install hook is required because ordinary package import triggers it.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently starts a remote binary loader. It downloads a platform-specific payload, writes it to a temporary path, and executes it detached.

- **Trigger:** Any require/import of the package entrypoint.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T16:42:17.333Z

### AI review details

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

- **Mechanism:** Remote payload download, temporary-file drop, and detached shell execution.

- **Attack narrative:** Requiring index.js silently loads \_loader.js. Its bootstrap routine contacts obfuscated remote worker hosts for a platform-specific binary, with DNS TXT payload reconstruction as fallback. It writes the payload to a temporary file, makes non-Windows files executable, and launches it detached through /bin/sh or cmd.exe. A timestamp file throttles repeated executions and errors are suppressed.

- **Rationale:** The import-time loader implements an unconsented remote native-payload execution chain. No install hook is required because ordinary package import triggers it.

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

- **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.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 block:** index.js imports \_loader.js on every package import., \_loader.js downloads platform binaries from four worker hosts., DNS TXT fallback reconstructs binary data from dl.wel1.ru subdomains., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then spawned detached via shell., Execution is rate-limited and failures are suppressed, consistent with stealthy payload delivery.

- **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint.

## Affected versions and remediation

This report applies to bigops-products-travel@35.7.1.

- Avoid installing bigops-products-travel@35.7.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
