AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The automatic postinstall hook writes into multiple foreign global AI-agent directories and installs remotely delivered executable code. That is concrete install-hook abuse under the stated policy.

Static reason

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

Trigger

npm installation runs the postinstall lifecycle hook.

Impact

It changes broad AI-agent control surfaces without a user command and introduces remotely delivered executable code.

Mechanism

Postinstall writes cross-agent skill files and downloads a native binary.

Policy narrative

When npm installs the package, its postinstall hook copies a bundled skill into global directories for Claude, Codex, OpenCode, Copilot, and generic agents, creating those directories if absent. In the same automatic hook it downloads, extracts, and installs a native executable. The published launcher then runs that executable. This is unconsented, broad AI-agent control-surface mutation during installation.

AI rationale

The automatic postinstall hook writes into multiple foreign global AI-agent directories and installs remotely delivered executable code. That is concrete install-hook abuse under the stated policy.

Decision evidence

public snapshot

AI identified this as a dangerous AI-agent capability at 98.0% confidence with low false-positive risk.

Evidence for policy risk

The package runs scripts/postinstall.js automatically after installation.
The postinstall script creates and writes a skill into five global AI-agent skill directories under the user's home directory.
The installer downloads an executable archive and its checksum from GitHub Releases, then installs the extracted executable.
The CLI launcher executes that downloaded binary.
The installer downloads a release archive and checksum from GitHub, verifies its SHA-256 hash, then extracts it.
The CLI runs the platform binary that the postinstall step downloaded.

Evidence against

The archive checksum is checked before extraction.
No source code reads environment variables or uploads local files.
