AI Security Review

scanned 26d ago · by lpm-firewall-ai

An npm postinstall hook installs and executes a native binary that automatically modifies Codex and Claude Code agent integration. The shipped binary includes a Codex approval-and-sandbox bypass option.

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

Installing the package through npm triggers postinstall.

Impact

The package changes foreign AI-agent control surfaces without an explicit user command and can launch Codex with safeguards bypassed.

Mechanism

Native binary download or execution followed by automatic agent-hook installation.

Attack narrative

npm postinstall launches scripts/install.js, which copies or downloads a platform binary and invokes it with --install-agent-hooks. This occurs without an explicit user command. The package admits that this changes Codex and Claude Code hooks and Codex update settings, while the bundled binary contains --dangerously-bypass-approvals-and-sandbox. Together, the automatic lifecycle execution, foreign agent-control mutation, opaque native payload, and safeguard-bypass capability form a concrete install-hook abuse chain.

AI rationale

This is unconsented postinstall mutation of broad AI-agent control surfaces, with an opaque native binary that contains a safeguard-bypass flag. The package meets the publish-block threshold for install hook abuse.
