AI Security Review

scanned 24d ago · by lpm-firewall-ai

Installation automatically fetches or copies a native executable and runs it to install AI-agent hooks. The remote download has no integrity verification and redirect destinations are not restricted.

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 runs the postinstall lifecycle hook.

Impact

A package install can execute a remotely supplied binary and alter Codex and Claude Code control surfaces without an explicit user command.

Mechanism

Unverified executable download followed by automatic agent-hook installation.

Attack narrative

The postinstall script downloads a platform executable from GitHub or Gitee, follows redirects, writes it into vendor, and executes it with --install-agent-hooks. It does not verify a checksum or signature. The package's own documentation identifies the invoked feature as installation of Codex and Claude Code hooks and a Codex configuration change, making this an unconsented install-time AI-agent control-surface mutation.

AI rationale

This is a concrete automatic lifecycle chain that executes an unverified native payload and installs hooks into foreign AI-agent environments. It meets the install-hook abuse publish-block boundary.
