AI Security Review

scanned 25d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Global installation automatically alters Claude Code's user-level skill control surface. The injected skill can cause later Claude Code sessions to run package-directed shell diagnostics and change MCP 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 while a Claude Code directory exists.

Impact

A package installation creates an unrequested persistent AI-agent instruction that can influence later sessions and execute commands.

Mechanism

Postinstall copies an auto-triggering Claude Code skill and downloads a remote extension.

Policy narrative

The npm postinstall launcher runs automatically. For a global installation, the script copies a bundled skill into the existing Claude Code user skill directory, where it is described as activating in later conversations. That skill directs Claude Code to execute shell commands directly and includes MCP configuration handling. The installer also fetches and extracts a remotely hosted extension archive. This is unconsented lifecycle mutation of a foreign AI-agent control surface.

AI rationale

The package has a concrete automatic postinstall path that persists instructions into Claude Code rather than requiring an explicit setup command. This meets the install-time AI-agent control-surface abuse block policy.
