AI Security Review

scanned 25d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package writes a persistent global Pi agent extension. The extension automatically adds repository-controlled instructions to Pi agent prompts.

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

npm postinstall during package installation, followed by a Pi agent start in a workbase.

Impact

A package installation can alter an AI agent control surface and cause later agents to consume project-controlled instructions.

Mechanism

Global agent-extension installation and system-prompt augmentation.

Policy narrative

The package's postinstall hook copies its Pi extension into the user's global Pi extension directory without an explicit user command. On later Pi agent starts, the extension reads a workbase's .agency/AGENTS.md and appends it to the agent system prompt. This is an unconsented install-time mutation of a broad AI-agent control surface.

AI rationale

The automatic global extension installation and subsequent prompt augmentation form a concrete AI-agent control-surface attack. No data exfiltration was required to establish the malicious install-hook behavior.
