AI Security Review

scanned 1d ago · by lpm-firewall-ai

The package's install dependency chain activates default-on analytics that transmits installation metadata to scarf.sh without affirmative installer consent. This is an automatic installation disclosure, so I classify it as malicious data exfiltration under the installation beacon policy.

Static reason

No blocking static signals were detected.

Trigger

Installing the package with npm when analytics has not been explicitly disabled.

Impact

Installation metadata is disclosed to a third-party analytics service without an affirmative opt-in.

Mechanism

The Scarf postinstall reporter gathers platform, architecture, Node version, and dependency metadata, then posts it to scarf.sh.

Attack narrative

During installation, Scarf runs its postinstall reporter. The reporter defaults to opted in, builds an installation metadata payload, and sends it to scarf.sh unless the installer opts out; its notice does not require a yes before sending.

Decision evidence

public snapshot

AI called this Malicious at 88.0% confidence as Malware with low false-positive risk.

Evidence for block

package.json declares Scarf as a runtime dependency, and Scarf's manifest runs its reporter during postinstall.
The reporter defaults to opted in; it proceeds unless the installer has opted out, without requiring an affirmative response.
The reporter builds an install payload containing platform, architecture, Node version, and dependency metadata.
The reporter selects scarf.sh and sends the payload in an HTTPS request.
