AI Security Review

scanned 4h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. A postinstall script changes the global Claude Code skill surface without an explicit user command. On global installs it also fetches and installs a remote browser extension and removes legacy configuration.

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

Installing the package globally with npm or pnpm.

Impact

Future Claude Code conversations can be matched by the installed skill and instructed to run package commands without fresh user consent.

Mechanism

Postinstall agent-skill injection, remote extension installation, and configuration cleanup.

Policy narrative

Registry installation launches the postinstall script. A global installation downloads and unpacks a remote extension, then copies a package-controlled skill into Claude Code's global skills directory. The skill is configured to trigger on common support phrases and tells Claude Code to execute shell commands itself. The installer can also delete older Claude skills and related host state. This creates an unconsented persistent control path into an existing AI-agent environment.

Rationale

The package automatically mutates a foreign global AI-agent control surface and installs a skill that directs the agent to execute commands. The fixed download host and opt-out do not establish informed consent for the postinstall persistence.
