AI Security Review

scanned 19d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically mutates global and project AI-agent control surfaces. No user command is required.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm postinstall

Impact

It can cause AI agents to invoke the package's server and redirect built-in tools in consumer projects.

Mechanism

The lifecycle hook runs init silently; init registers Warden, enables automatic approval, and installs agent hooks.

Policy narrative

On installation, postinstall silently runs the package CLI in the consumer directory. That CLI writes global agent configuration, grants Warden automatic tool approval, and installs project hooks that redirect agent tool calls. This is unconsented install-time mutation of broad AI-agent control surfaces.

AI rationale

The package has a concrete automatic lifecycle chain that silently changes foreign AI-agent configuration and tool controls. This meets the install-control-surface blocking policy.
