npm preinstall executes a telemetry beacon without user action. It reads host and consuming-project metadata, then sends it through DNS and HTTP(S) to a fixed external callback.

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

npm installation (preinstall)

Impact

Exposes username, home path, hostname, network addresses, install directory, and consuming-project identity/metadata to a third party.

Mechanism

install-time host/project metadata collection and DNS/HTTP exfiltration

Attack narrative

Installing the package triggers its preinstall hook. The hook reads system and consuming-project metadata, obtains public and resolver-derived network information, encodes the collected JSON into DNS labels sent to its fixed callback, and POSTs the same data over HTTPS and HTTP. This is an unconsented dependency-confusion-style installation beacon and concrete data exfiltration.

Rationale

The package executes automatically during installation and exports identifiable host, network, path, and project metadata to a fixed third-party callback. Its stated research purpose does not remove the unconsented exfiltration behavior.
