AI Security Review
scanned 4d ago · by lpm-firewall-aiThe parent package installs a remote dependency whose preinstall hook automatically sends encoded host and user identifiers to an OAST collector. This is an unconsented installation-time disclosure, so the package should be blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package runs the dependency's preinstall hook.
Impact
The collector can receive identifying information and the installer's network address without installer consent.
Mechanism
The hook hex-encodes the hostname, home directory, and username, places each value in a subdomain, and makes HTTP requests to that domain.
Attack narrative
Installing the package installs a dependency with an automatic preinstall hook. That hook encodes the installer's hostname, home directory, and username and sends requests to an OAST domain containing those values. The source shows no recipient-specific consent or opt-in gate for this disclosure.
AI rationale
The parent package installs a remote dependency whose preinstall hook automatically sends encoded host and user identifiers to an OAST collector. This is an unconsented installation-time disclosure, so the package should be blocked.

Evidence for block
- The package depends on a remote tarball that installs `ltidisafe`.
- The dependency's preinstall hook runs `test.js` automatically.
- The hook encodes the machine hostname, home directory, and username into subdomains of an OAST domain and calls the download check for each value.
- The dependency sends an HTTP request to the supplied URL.
