AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall performs package-aligned binary setup with a hash check, but also sends identifying installation telemetry by default. That supports a warning for potential data disclosure, not a publish block.
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
Installing the package runs its postinstall hook, which invokes the installer and reports the outcome unless telemetry is disabled by an environment variable.
Impact
Installation metadata may be disclosed to the logging service. The inspected code does not establish credential theft or malicious payload behavior.
Mechanism
The installer sends a POST containing installation details to a fixed endpoint. It also downloads a platform binary and replaces the package's executable after a hash check.
AI rationale
The postinstall performs package-aligned binary setup with a hash check, but also sends identifying installation telemetry by default. That supports a warning for potential data disclosure, not a publish block.

Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook automatically runs the installer.
- The installer sends installation telemetry by default to a fixed logging endpoint; it includes a hostname and values derived from the work-root and session environment variables.
- The installer downloads a platform binary and replaces the package's placeholder executable after checking its SHA-256 hash.
- Telemetry can be disabled with an environment variable, but the installer invokes it after the install outcome by default.
Evidence against
- The downloaded binary is checked against a package-provided SHA-256 value before being written.
- The telemetry endpoint is fixed in the installer, and telemetry errors are caught rather than affecting installation.
