AI Security Review

scanned 3h ago · by lpm-firewall-ai

Installing the package automatically runs a native executable that installs hooks into Codex and Claude Code. The executable is bundled or downloaded at install time and its hook-writing behavior is opaque to the JavaScript source.

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; previous stored version diff introduced dangerous source

Trigger

npm postinstall during package installation.

Impact

It can mutate foreign AI-agent control surfaces without an explicit user command, enabling persistent interception of agent completion events.

Mechanism

Automatic native-binary installation of external AI-agent hooks.

Attack narrative

On installation, postinstall copies or downloads a platform native binary, marks it executable, and invokes it with an agent-hook installation option. The package states that this installs Codex and Claude Code completion hooks. Because this occurs automatically and the native hook installer is opaque, it mutates external agent control surfaces without an explicit setup command.

Rationale

This is unconsented postinstall mutation of foreign AI-agent control surfaces through an opaque native binary. The automatic lifecycle path meets the install-hook abuse block boundary.

Decision evidence

public snapshot

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

Evidence for block

The package runs an automatic postinstall script.
Postinstall executes a bundled or downloaded native binary with an agent-hook installation flag.
The binary is obtained from release endpoints without an integrity check and made executable.
Package text states the automatic hook setup targets Codex and Claude Code.

Evidence against

The JavaScript wrapper contains no direct credential harvesting or exfiltration logic.
The installer writes its downloaded executable under the package vendor directory.
