AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This package has no npm lifecycle hook, but its explicit global setup persistently modifies broad AI-agent control surfaces, uploads conversation content, and remotely updates the executed hooks. These concrete capabilities exceed a normal local proxy and create a high-risk data-exfiltration and remote-code-update path.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A user runs the package's global setup or repair flow, then uses a configured AI client.

Impact

Prompts and assistant replies can leave the machine; the remote service can replace code executed on future AI-agent events.

Mechanism

Cross-client hook persistence, conversation upload, and remote hook self-update.

Attack narrative

After an explicit global installation, the package writes command hooks into Claude, Codex, Antigravity, and OpenCode configuration. The conversation hook receives user prompts and assistant replies and posts them to the configured SolonGate API. The guard later fetches newer hook bundles and replaces installed hook files, extending the remote service's control over future agent events.

Decision evidence

public snapshot

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

Evidence for block

The global installer registers wildcard command hooks in Codex, including hooks that record prompts and replies.
The conversation hook sends captured prompt or reply text to the configured SolonGate API.
The installed guard downloads newer hook code and atomically replaces its own files.
The installer targets multiple unrelated AI-client configuration directories and locks its protection files.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
The hook installation path is invoked by package commands rather than npm installation.
