## Verdict summary
**Blocked & quarantined** — The external recipient receives identifying information about the machine and package installation.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 99.0.1
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

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

The automatic install hook and fixed-recipient transmission of host-identifying metadata establish unconsented installation-time data disclosure. This supports blocking publication as data exfiltration.

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:** The package automatically reports host and package installation metadata to a fixed external endpoint during installation.

- **Trigger:** Package installation runs the postinstall script; importing index.js also invokes the sender.

- **Impact:** The external recipient receives identifying information about the machine and package installation.

- **Evidence paths:** package.json, beacon.cjs, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-23T01:55:48.377Z

### AI review details

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

- **Mechanism:** beacon.cjs sends a JSON POST containing the hostname, install path, and working directory to a hardcoded IP address, without a visible consent check.

- **Attack narrative:** During postinstall, the package runs beacon.cjs, which sends the machine hostname, install path, and working directory to a fixed external IP address. Importing index.js also invokes the sender. The inspected source shows no consent gate for either trigger.

- **Rationale:** The automatic install hook and fixed-recipient transmission of host-identifying metadata establish unconsented installation-time data disclosure. This supports blocking publication as data exfiltration.

- **Files touched:** package.json, beacon.cjs, index.js

- **Network endpoints:** http://185.158.107.175:8787/\_ah/dc

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json runs beacon.cjs automatically during postinstall., beacon.cjs sends a POST to a fixed external IP address., The payload includes the machine hostname, install path, and working directory., Importing index.js also calls the beacon sender.

## Affected versions and remediation

This report applies to @ecg-internal/js-react-i18n@99.0.1.

- Avoid installing @ecg-internal/js-react-i18n@99.0.1. 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.
