## Verdict summary
**Blocked & quarantined** — The collector receives machine and project installation identifiers without an affirmative installer choice.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 2.0.0
- **Selected version is latest:** No
- **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.

Source confirms automatic installation-time disclosure of identifying host and project metadata to a fixed external collector, with no affirmative consent gate. The README's research-test description does not establish consent from installers.

## Security analysis

### Published attack-surface review

- **Summary:** The package automatically reports identifying installation metadata to a fixed external collector. The source shows no installer-consent gate.

- **Trigger:** Package installation runs the postinstall hook; importing the package entrypoint also fires the beacon.

- **Impact:** The collector receives machine and project installation identifiers without an affirmative installer choice.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-23T00:50:22.737Z

### AI review details

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

- **Mechanism:** The beacon sends an HTTP POST with the machine hostname, installation path, and current directory.

- **Attack narrative:** The postinstall hook invokes a beacon that sends the machine hostname and installation locations to a fixed external HTTP endpoint. The package entrypoint also fires the beacon on import. The README calls this a research test, but that claim does not establish installer consent.

- **Rationale:** Source confirms automatic installation-time disclosure of identifying host and project metadata to a fixed external collector, with no affirmative consent gate. The README's research-test description does not establish consent from installers.

- **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 the beacon during postinstall., beacon.cjs uses a fixed external HTTP collector and labels requests with the package name., beacon.cjs sends a POST containing the serialized payload., The payload includes the machine hostname, installation path, and current directory., index.js fires the beacon when the package entrypoint is loaded., README.md describes a research test, but source provides no installer-consent gate.

## Affected versions and remediation

This report applies to @grabcad/grabcad-shop-shared@2.0.0.

- Avoid installing @grabcad/grabcad-shop-shared@2.0.0. 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.
