AI Security Review

scanned 11d ago · by lpm-firewall-ai

Installing the package automatically fetches and executes an opaque external release payload. The package snapshot does not contain that payload for review.

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 postinstall execution.

Impact

A substituted or compromised release source could execute code during package installation; no specific malicious payload is present in this snapshot.

Mechanism

The installer selects a release URL, downloads an archive and checksum file, extracts the archive, then invokes its install script through bash.

AI rationale

The package has an automatic opaque remote-payload installation path. Static inspection found no concrete secret theft, destructive action, or foreign agent-control mutation in the shipped JavaScript.

Evidence for warning

The package runs its installer automatically in postinstall.
The installer downloads a release archive from a configurable base URL during installation.
The installer runs a bash script from the downloaded release with inherited environment variables.

Evidence against

The installer compares the archive against a downloaded SHA-256 sums file.
No direct credential collection or exfiltration sink was found in the inspected package source.
