AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package has a real, persistent AI-agent control surface and remote-update capability, so it warrants a warning. Source inspection found no automatic npm lifecycle execution or concrete unconsented installation behavior required for a block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A user runs the SolonGate setup or repair flow after obtaining a credential, then uses a configured AI client.

Impact

The package can observe AI-agent activity, alter tool handling, transmit redacted conversation data, and retain control through installed hooks.

Mechanism

Persistent AI-client hook registration, conversation telemetry, and remote hook updates.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 95.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

An explicit guarded-install flow writes hooks and registers them across AI clients.
A hook sends redacted user and assistant conversation content to the configured SolonGate API when an API key is present.
The installed guard can download and atomically replace hook code from the configured API.
The installer locks its hook and AI-client configuration targets after installation.

Evidence against

package.json has no preinstall, install, postinstall, or prepare lifecycle hook.
The control-surface changes occur in an explicit setup or repair path and require a SolonGate credential.
The conversation sender checks for a credential and applies local redaction before posting.
