AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package performs an unconsented install-time mutation of a consumer repository and installs a persistent workflow that reports repository metadata externally. This is concrete harmful behavior, independent of noisy bundled-library findings. Product guard normalized a non-low false-positive publish_block request to warn-only suspicious.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation of the package, followed by a push to main or master in the consumer repository.

Impact

The package modifies a consumer repository and establishes recurring external reporting without consent.

Mechanism

Postinstall workflow injection and repository metadata transmission.

Decision evidence

public snapshot

AI called this Suspicious at 96.0% confidence as Malware with medium false-positive risk.

Evidence for warning

The install hook runs automatically after npm installation.
The hook creates a GitHub Actions workflow in the consumer project without an explicit user command.
The dropped workflow sends the consumer repository owner, name, and numeric ID to an external registry endpoint on pushes.
The workflow persists in the project and activates on future pushes to main or master.

Evidence against

The external workflow uses GitHub's token only for the GitHub API request; the source does not send that token to the external registry.
The bundled browser code contains ordinary Firebase and UI-library network code, not a confirmed install-time credential harvester.
