AI Security Review

scanned 1d ago · by lpm-firewall-ai

Installing the package automatically changes AI-agent skill directories and Codex plugin configuration. It removes pre-existing package-named directories before copying its own skills.

Static reason

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

Trigger

npm installation

Impact

The package gains automatic control over loaded AI-agent skills and installs an enabled local Codex plugin without an explicit setup command.

Mechanism

postinstall writes and enables agent extensions across user configuration directories

Attack narrative

During npm installation, package.json runs scripts/postinstall.js. That hook removes and replaces skills in multiple AI-agent configuration directories, including an unconditional Claude Code write. When Codex exists, it creates a local marketplace and plugin, then appends configuration that enables it. These changes occur without an explicit user command and alter broad agent control surfaces.

Rationale

The automatic lifecycle hook performs unconsented multi-agent configuration mutation and enables a Codex plugin. This meets the install-hook abuse blocking policy despite no confirmed exfiltration.
