AI Security Review
scanned 13d ago · by lpm-firewall-aiThe postinstall hook installs a digest-checked native executable from package-aligned sources and runs it during installation. Because the executable's behavior is opaque in this source snapshot, this is an unresolved payload risk rather than evidence of a concrete attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package through a package manager that runs postinstall.
Impact
The fetched executable runs during package installation, so its behavior is not auditable from the included JavaScript source.
Mechanism
The hook fetches the platform binary from the manifest's CDN, with a project release fallback, checks its digest, installs it, and invokes it with `+connect --refresh`.
AI rationale
The postinstall hook installs a digest-checked native executable from package-aligned sources and runs it during installation. Because the executable's behavior is opaque in this source snapshot, this is an unresolved payload risk rather than evidence of a concrete attack.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook downloads and installs a platform-specific executable from the package manifest.
- The hook checks the downloaded file against the manifest SHA-256 digest before installing it.
- After installation, the hook invokes the executable with `+connect --refresh`; that opaque binary is outside the inspected source files.
Evidence against
- The download uses HTTPS and the stable GitHub fallback is restricted to this project's release path.
- The installer verifies the downloaded binary's digest before replacing the installed executable.
