AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This package performs undisclosed, automatic install-time collection and remote transmission of a machine fingerprint. Its explicit agent configuration command is user-invoked, but that does not mitigate the postinstall exfiltration.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm installation

Impact

The publisher receives a persistent device/user identifier and local AI-client context without an interactive consent step.

Mechanism

automatic fingerprint telemetry exfiltration

Attack narrative

The npm postinstall hook runs automatically. It builds an install deduplication key from the local hostname and username, adds MCP-client detection and platform metadata, and sends that payload to the publisher's Convex service. The telemetry call is intentionally non-blocking and suppressed on failure, so installation continues without surfacing whether data was sent.

AI rationale

Network endpoints1

Decision evidence

public snapshot

AI called this Malicious at 94.0% confidence as Malware with low false-positive risk.

Evidence for block

The manifest automatically runs a postinstall program.
Postinstall collects a hostname-and-username machine fingerprint and MCP-client information.
The telemetry client sends event payloads to a remote Convex endpoint and ignores failures.
The fingerprint function explicitly returns the local hostname and username.

Evidence against

The inspected explicit MCP configuration writer is a user-invoked CLI command, not called by postinstall.
No self-dependency on this package name appears in the manifest dependencies.
