AI Security Review

scanned 1mo ago · by lpm-firewall-ai

Installation fetches an unbundled platform release, extracts it inside the package, and runs its installer. The downloaded payload is outside the inspected npm tarball and can execute during postinstall.

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

Impact

A compromised release endpoint or redirect can run code during package installation.

Mechanism

remote payload download, extraction, and shell execution

AI rationale

No direct credential theft, exfiltration, or foreign agent-control mutation is present in the inspected wrapper. However, automatic installation executes a remotely downloaded payload whose checksum comes from the same source, leaving a material staged-payload risk.

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.

Stop threats before they install.

Evidence for warning

The postinstall hook runs automatically during npm installation.
The installer downloads a platform archive and checksum from GitHub at install time.
It extracts the downloaded archive and executes its install.sh with bash.
The checksum is fetched from the same remote location, so it does not independently authenticate the payload.

Evidence against

The only default download host is the package-aligned GitHub repository release path.
The inspected npm wrapper contains no credential harvesting or exfiltration logic.
