@reason-machines/cli-win32-x64@0.2.415: Manual Review npm

AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection did not confirm malicious behavior, but the bounded analysis of the shipped native executable does not resolve credential collection reachability or its destination. Manual review is warranted because that executable is a material package component.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Unknown; the inspected executable analysis does not establish whether these candidates are reachable.

Impact

Potential exposure cannot be assessed without resolving executable reachability and tracing the credential data flow.

Mechanism

The embedded source candidate reads provider credentials and local authentication configuration; no matching send operation was established in the inspected excerpt.

AI rationale

Source inspection did not confirm malicious behavior, but the bounded analysis of the shipped native executable does not resolve credential collection reachability or its destination. Manual review is warranted because that executable is a material package component.

Evidence

Decision evidence

public snapshot

AI called this Manual Review at 78.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest describes a Windows x64 CLI binary and defines no lifecycle scripts.
The bundled sandbox runtime names agent and project configuration paths in its protected-path list.
A bounded executable-source excerpt collects provider API keys and reads local agent authentication configuration; the inspected excerpt does not establish where that data goes.
The executable analysis warns that its embedded source windows do not establish loader reachability or rule out other native behavior.

Evidence against

The package manifest contains no install lifecycle hooks. The listed sandbox paths and credential sources alone do not prove an attack.
