AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall downloads an unverified native binary and immediately invokes it to install Codex and Claude Code hooks. This mutates foreign AI-agent control surfaces without an explicit user command.

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 uninspected binary can alter Codex and Claude Code completion-hook configuration during installation.

Mechanism

remote binary download followed by automatic agent-hook installation

Policy narrative

Installing the package runs its lifecycle script. That script downloads a platform-specific executable from GitHub or Gitee without a checksum or signature verification, saves it under vendor/, and executes it with --install-agent-hooks. The package documentation states this installs Codex notify and Claude Code Stop hooks. Because this happens automatically at postinstall and the executable is absent from the package, its configuration writes and behavior cannot be audited from the published source.

Rationale

This is an unconsented postinstall mutation of foreign AI-agent control surfaces through an unverified remote payload. The source directly establishes the installation and execution chain.
