AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic transmission of a hostname-and-username fingerprint is a concrete privacy-risking install-time data flow. The inspected source does not establish broader agent-control mutation or credential theft, so blocking is not warranted.

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

Installing the package through npm runs postinstall.

Impact

The vendor receives a persistent local identity value and MCP-client information without an interactive consent step.

Mechanism

Automatic collection and transmission of a machine fingerprint as install telemetry.

AI rationale

Evidence

package.jsondist/postinstall.jsdist/session.jsdist/funnel-client.js~/.apiclaw/funnel-markers.json

Network endpoints1

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs a postinstall hook automatically.
That hook obtains a fingerprint before recording an install event.
The fingerprint is the local hostname and username.
Telemetry is enabled unless the user sets an environment-variable opt-out, and it sends the event to the vendor Convex service.

Evidence against

The MCP configuration writers are reached through explicit CLI setup commands, not the install hook.
The inspected authentication flow sends its own APIClaw session token to the configured APIClaw service.
