@reason-machines/cli-darwin-x64@0.2.389: Manual Review npm

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The manifest has no lifecycle scripts, and the flagged JavaScript excerpt does not prove malicious behavior. The primary native executable remains materially unresolved because the supplied analysis cannot establish code reachability or exclude other native behavior, so manual review is appropriate.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Running the packaged native CLI; its full activation paths could not be established from the available analysis.

Impact

No malicious effect was verified; native executable behavior remains uncertain.

Mechanism

The reviewed JavaScript excerpt lists configuration paths, while the native analysis does not establish which embedded code is loaded or whether other behavior exists.

AI rationale

The manifest has no lifecycle scripts, and the flagged JavaScript excerpt does not prove malicious behavior. The primary native executable remains materially unresolved because the supplied analysis cannot establish code reachability or exclude other native behavior, so manual review is appropriate.

Decision evidence

public snapshot

AI called this Manual Review at 91.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies a Darwin x64 CLI package and shows no lifecycle scripts in the inspected manifest.
The flagged JavaScript excerpt lists project configuration paths; it does not establish a harmful configuration change.
The offline analysis says its bounded native source windows cannot establish executable reachability or exclude other native behavior.
An embedded CLI excerpt describes access to current login tokens, but does not establish their recipients or complete transfer behavior.
