AI Security Review

scanned 16d ago · by lpm-firewall-ai

The install-time download, platform binary setup, and Python SDK installation are consistent with this CLI package’s stated code structure. Inspection found no concrete attack behavior.

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

Package installation invokes the postinstall hook; normal CLI use launches the selected platform binary.

Impact

The inspected behavior installs and launches the package’s intended CLI; no concrete malicious effect was established.

Mechanism

The hook downloads and extracts a platform archive, while the launcher selects the matching optional package binary and forwards CLI arguments.

AI rationale

The install-time download, platform binary setup, and Python SDK installation are consistent with this CLI package’s stated code structure. Inspection found no concrete attack behavior.

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs postinstall.mjs and declares platform-specific optional packages for this product.
bin/tfcode.js resolves the matching platform package binary and launches it with the caller’s arguments and environment.
postinstall.mjs fetches and installs a platform binary from the vendor’s release host, then attempts to install the ToothFairyAI Python SDK.
