AI Security Review
scanned 15h ago · by lpm-firewall-aiThe preinstall hook sends local system identity data to an unrelated external callback without consent. This is malicious install-time data exfiltration.
Static reason
One or more suspicious static signals were detected.
Trigger
The package's preinstall hook runs during installation.
Impact
An external collector receives local user and group identity information.
Mechanism
It pipes `id` output through base64 and posts it to a fixed Pipedream endpoint.
Attack narrative
During installation, the preinstall script encodes the output of `id` and sends it to a fixed Pipedream callback. This exposes system identity information without the installer's consent.
AI rationale
The preinstall hook sends local system identity data to an unrelated external callback without consent. This is malicious install-time data exfiltration.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The preinstall hook sends the base64-encoded output of `id` to a fixed Pipedream callback, exposing system identity data during installation without consent.
Evidence against
- The main entry point only calls `console.log(1);`.
