AI Security Review

scanned 26d ago · by lpm-firewall-ai

Installing the package automatically obtains or copies a native executable, marks it executable, and runs its agent-hook installer. This unconsented lifecycle path can alter external AI-agent control surfaces through opaque code.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation

Impact

The executable can persist hooks or change AI-agent behavior outside the installed package.

Mechanism

postinstall remote binary execution and agent-hook setup

Attack narrative

npm invokes scripts/install.js after installation. The script accepts environment-controlled repository locations, copies a bundled native executable or downloads one without a checksum or signature check, makes it executable, and launches it with --install-agent-hooks. That automatic opaque binary execution targets agent hooks rather than only package-local setup, creating an unconsented path to alter AI-agent behavior.

AI rationale

The automatic postinstall executes opaque native code specifically to install agent hooks, including code obtained without integrity verification. This is a concrete install-hook abuse path affecting a foreign AI-agent control surface.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The postinstall hook runs automatically during npm installation.
The installer downloads a platform binary from configurable GitHub or Gitee locations without integrity verification.
Downloaded or bundled native code is made executable and run automatically with --install-agent-hooks.
The invoked binary is opaque native code, so its agent-hook changes cannot be audited from the JavaScript source.

Evidence against

The JavaScript installer limits its stated downloads to the package's named release repositories.
No JavaScript source directly harvests or transmits credentials.
